Self-evaluation of boiler staff in power plant

Self-evaluation of boiler staff in power plant

As a power plant boiler employee, what is your evaluation of yourself? Below I have compiled the self-appraisal of boiler employees in power plant for you, hoping to help you!

Self-evaluation of boiler staff in power plant-I have been engaged in maintenance technical management since 20xx. Through the analysis and research on the field equipment problems, combined with the theoretical knowledge I have learned, I put forward a solution, and gradually formed a set of advanced technical management concepts. Through these years' work, I have done some work and made some achievements. The professional and technical work in recent years is summarized as follows.

In 20xx, the company carried out overhaul of No.9 and 10 boilers and medium repair of 1 1 boilers. In the overhaul of No.9 and 10 boilers, the water film dust collector was transformed into electrostatic dust collector. Before the overhaul, the tail air leakage coefficient of 10 boiler seriously exceeded the standard. Through the inspection of the air leakage position of the boiler body and tail, the equipment base number was found out, and the air leakage position was seriously and thoroughly treated. The air leakage coefficient of 10 boiler was reduced from the original 0.46 by replacing the lower air preheater, replacing the anti-wear short tube of the preheater, and resealing the expansion joint, furnace door, furnace wall and through-wall tube. During the overhaul of No.9 boiler, the platen superheater was replaced. The whole process of quality management and supervision was carried out from the bending of the tube bank of the platen superheater, the design of the welding joint position of the tube bank, the demolition of the old tube bank, the installation of the tube bank, the sealing of the ceiling tube and the recovery of the heat preservation of the furnace top, which ensured the quality, the qualified rate of the welded joint was 100%, and the water pressure test was successful at one time.

The burner of 1 1 boiler was reformed during the medium repair. 1 1 boiler is produced by Beijing Bawei Boiler Factory. The combustion mode is that the front and rear walls are opposite. Burners are arranged in three layers, each layer has 6 * * * 18. Because there is a big difference between the designed coal type of the boiler and the actual coal type, in order to make the boiler burn stably in operation, the external secondary air of the burner is changed from the original axial air intake to the radial air intake, which increases the air intake of the external secondary air. After transformation, the effect is obvious, and the boiler runs stably under the condition of burning actual coal. 1 1 boiler has serious coking during operation, and the falling off of large coke blocks leads to unstable negative pressure in the boiler, which damages the bottom of the slag catcher, resulting in water leakage at the bottom, welding of the north support of the slag catcher and other defects. After many consultations with Bawei Company, it was decided to remove part of the flame retardant tape, remove the refractory plastic on the surface of the water wall, remove the pins welded on the surface of the water wall tube, and finally polish the position of each pin. Through the overall quality supervision and management of each process and strict quality control, the maintenance quality of this work is guaranteed. Practice has proved that there is no leakage caused by construction quality in this part in the future boiler operation. The steam source of the bottom heating system of 1 1 and 12 boilers is high-pressure service steam, but there are some problems such as long heating time and large loss of auxiliary fuel when the boilers are started. The company decided to reform the steam sources of the bottom heating systems of two boilers, and I completed the technical scheme of reforming the steam sources of 1 1 and 12 boilers. The reformed bottom heating steam source is the saturated steam of adjacent boilers, and the steam is taken from the saturated steam outlet of the steam drum for 4mpas. In order to ensure the uniformity of steam extraction from the drum, every other pipe is perforated, with a total of 6 pipes.

20xx began to implement the steam source reconstruction project of bottom heating system in April. After many times of communication with the design department and on-site actual investigation, the pipeline direction was finally determined, and 450m (φ133x12) pipeline was erected, and 206 high-pressure welded joints were completed, all of which were qualified at one time. 1 1, 12 boiler minor repairs, the improvement and docking of the heating systems at the bottom of the two boilers were completed and put into use at the beginning of minor repairs. The effect is remarkable. After the system was put into operation, the steam drum pressure was heated to 0.8 ~ 1 MPa, and the grid was connected 5 hours in advance, saving 25 tons of fuel.

As a workshop technician, I guided the activities of qc group in ontology class, put forward the topic of "reducing the air leakage coefficient of 10 boiler", and won the first prize in the national "Shunjie Cup" qc competition on behalf of the company.

During the overhaul of No.9 boiler in 2004, a and b suction fans were equipped with hydraulic couplings, which reduced the running current of suction fans and achieved good power saving effect. In particular, the design of hydraulic coupling foundation was checked according to the equipment drawings, and the dimensions of each part were measured many times on site, and the connection with the original foundation was considered, so that the installed equipment operated stably. Comp5~7any did not stop the energy-saving transformation of the suction fan. During the overhaul of 12 boiler, the original suction fan impeller was designed to be large, with a diameter of 3200mm. The load was adjusted according to the opening of the inlet baffle, and the maximum opening of the baffle was only 20% ~ 30%. Therefore, the diameter of the impeller was cut during the overhaul, and the diameter of the impeller after cutting was 3040mm, and the opening of the baffle was also increased to 40% ~. After achieving a certain energy-saving effect, the blades are rotated into small impellers with serrated middle disks, which further reduces the current by 3 ~ 4a. In 2005, with the further reduction of inverter cost, the suction fan motors of boilers 1 1 and 12 were gradually transformed into frequency conversion equipment, which further greatly reduced the power consumption of fans, and only the frequency conversion transformation of suction fans decreased by about 0.

In 2005, I transferred from the Biotechnology Department to the Boiler Branch, and successfully completed the A-level maintenance of boiler 1 1. Earnestly implement the project responsibility system, carry out the maintenance project to individuals, so that each work can be implemented, and complete the boiler burner reconstruction project of 1 1. In order to adapt to the change of coal type and make the boiler burn stably under ground load, the lower burner was reformed. The interior of the original burner was uniform. After the transformation, the homogeneous fluid is removed, the diameter of the primary air duct is appropriately increased, and three concentration rings are installed inside, so that the concentrated pulverized coal passes through the center of the concentration rings and burns centrally to achieve the purpose of stable combustion. After the transformation, the test shows that the effect is obvious, and the boiler burns stably under 50% load. Completing the seal transformation of the inlet and outlet of the coal mill not only solves the problem of coal leakage at the inlet and outlet of the coal mill, but also provides a guarantee for the optimal control of the pulverizing system. After the transformation, the unit consumption of the coal mill has been reduced to the minimum. In the A-level maintenance of 1 1 boiler, the dust removal efficiency was obviously improved through comprehensive treatment of electrostatic dust removal. The ash hopper of economizer has not discharged pollutants normally for many years. Through brainstorming and transformation, the ash hopper can run normally. In order to reduce the unknown leakage of the boiler, every valve was inspected during the overhaul, quality control was strictly carried out, and all valves were disassembled and repaired. Unprecedented achievements have been made in the hydraulic test, and the pressure drop in five minutes is only 0. 1mpa. Due to the implementation of the project responsibility system, the responsibility of every employee has been strengthened, and many major defects have been found in time, such as 9 cracks in the drum pipe, cracks in the joint surface of the nail polish big gear ring, scaling in the lower pipe of the air preheater, etc.

Usually, we pay attention to the process control of maintenance quality, and require that every major work be carried out in strict accordance with the requirements of the maintenance process card, strict acceptance procedures, important supervision and inspection projects, and conscientiously implement the three-level acceptance system to ensure the quality of equipment maintenance.

In 20xx, the company's fifth phase project 13 unit was put into production. Desulfurization equipment of three 200mw units put into use. I actively prepare for the fifth stage and desulfurization project. Since the start of the fifth phase and desulfurization project, I have specially organized and established the fifth phase and desulfurization production preparation team. I am the team leader, making special rules, defining members, defining responsibilities and carrying out related work. Through on-site inspection, drawing search and centralized discussion, 285 defects were found in 13 boiler and 62 defects were found in desulfurization. Especially in the early stage of desulfurization, a lot of work was done, including the connection of steam source and water source of desulfurization island, pipeline transition in the early stage, and 55 times of arrival acceptance of desulfurization equipment, and five major defects of the equipment were found. At the same time, the training of new equipment was strengthened, which laid the foundation for the smooth handover of equipment.

The debugging of new equipment is a new challenge for maintenance. Due to the problems existing in equipment installation and the different familiarity of maintenance personnel with the new equipment, there are many defects in the equipment. How to ensure the normal operation of the new equipment has become an urgent problem to be solved. As the main person in charge of new equipment maintenance, he divided the new equipment into various teams and groups in the shortest time, defined his responsibilities, shifted the pressure of eliminating defects to every employee, formulated detailed assessment rules, carefully analyzed equipment problems, formulated countermeasures, organized implementation, and finally earnestly summed up experience to further improve. Through many explorations and efforts, the characteristics of the equipment have been gradually mastered, and the operation of the equipment has gradually stabilized.

Do a good job in the implementation of the "three standards in one" standard. By identifying the valid documents, the list of valid records, compiling the department's maintenance procedures and maintenance flow cards, and training the knowledge of "three standards in one", we successfully passed the internal audit and external audit of standard implementation, standardized all the work of the Division, and truly achieved what to write, what to write and qualified.

In 20xx, the company successfully completed various maintenance tasks, especially 12 boiler class A maintenance task. During the overhaul of 12 boiler, all employees of the Division were organized to overcome various difficulties, many major equipment hidden dangers were discovered, and a number of major special projects were completed. Through comprehensive management, the quality of equipment is improved and the stability of equipment operation is ensured. During the overhaul, the project responsibility system was seriously implemented, and the test results were excellent in the later period of overhaul. The division won the glorious title of "four guarantees and one innovation" advanced collective in the overhaul.

13 boiler is a new equipment put into production. Because of the instability of the new equipment, the maintenance personnel are not familiar with the maintenance process, resulting in two boiler shutdowns, and the internal support of the slag catcher gear box and electrostatic precipitator is damaged, resulting in two boiler shutdowns. Branch managers learn from their mistakes and meet difficult challenges with a positive attitude. With the strong support of the factory department, they strengthened the equipment management, reformed the equipment, eliminated the hidden dangers of the equipment, and ensured the system and drying of the slag catcher.

Actively take over desulfurization equipment, complete the transformation of desulfurization ggh soot blowing steam source pipeline 1 1 and 13, leak pump, replace mechanical seal, etc. To ensure the stable operation of the equipment.

Pay attention to and strengthen the civilized sanitation management of equipment site, from the standard production of boiler 13 to the civilized management of desulfurization equipment, greatly improve the sanitation status of equipment on site, insist on thoroughly cleaning the site sanitation every Friday, and check and implement the assessment. The workers' awareness of civilization and hygiene has been greatly improved.

In short, some work has been done in professional technology in recent years. However, as a manager engaged in boiler maintenance, how to reduce the "four tubes" leakage of boilers is an eternal theme. Although the number of "four tubes" of boilers in 20xx is zero, it does not mean that there are no loopholes in our work. Secondly, in terms of professional technology, there are still many places to learn. Therefore, only by calming down, being pragmatic and willing to contribute can we further improve our professional management level.

Self-identity of boiler employees in the second power plant. My name is * *, male, Han nationality. Born in * * * *, he worked in * * * and was assigned to work in the second boiler room of Luobo Group. When I first joined the company, I learned safety first. The master told me in detail the previous accident cases, safety operation procedures and precautions, which I couldn't learn from books. I listen carefully, take notes, and then apply them in practice. Through my own efforts, I passed the Luoyang real estate qualification examination and obtained the qualification certificate of boiler secondary technician. In a blink of an eye, I have been a boiler operator for more than 20 years. I have been working hard to learn professional and technical knowledge with full enthusiasm, strictly abide by various operating procedures, humbly ask for advice, unite colleagues, constantly improve my working ability and do my job well. In order to better complete the future work, the previous work is summarized as follows:

First, strengthen theoretical study and improve personal quality.

Study hard in technology, memorize the operation rules in theory, strictly abide by the operation rules in practice, cultivate individual independent operation ability, ensure that misoperation accidents do not occur, write down the problems encountered in work, experience gained and matters needing attention at any time, humbly ask the old employees and leaders about the working principle of the steam turbine, learn how to operate the boiler safely and correctly, and adjust the boiler operation reasonably according to the needs of the power generation steam turbine. I know it takes time to master the boiler major. In order to constantly improve their theoretical level, actively participate in theoretical training activities organized by the unit, so that theory can better serve practice;

Second, work hard and do your job well.

I have been working as a stoker for boiler operation. I usually work hard. After years of work accumulation, I also summed up some work experience, found problems and promptly investigated potential safety hazards. And ensures the safe and efficient operation of the boiler. So far there have been no man-made accidents. Because technology is dead and ability is alive. In all kinds of unexpected accidents, we can deal with them decisively, nip in the bud and minimize the actual events. Therefore, quick and accurate judgment ability and flexible learning and application can do better.

In the specific work, stick to your post, concentrate your thoughts and operate strictly. Patrol according to regulations when on duty to check the operation of various equipment and devices. At the same time, carefully record the boiler operation, carefully check the daily records, and count the tools during the shift change. At the same time, I also regularly check and maintain the boiler and its auxiliary equipment, and take effective measures according to the actual situation when I find that the abnormal phenomenon of the boiler is dangerous.

Second, do a good job of fireman operation to ensure work safety.

In the work of safety production, assist the employees of this class to do all the work of this class, and ensure the value and quantity to complete all the tasks assigned by the superior leaders. Strengthen equipment inspection, improve equipment reliability, rationally adjust boiler operation mode, and ensure the completion of various production indicators issued by the factory. Avoid personal injury, equipment damage, fire accidents and major accidents caused by human responsibility.

Third, the new direction of work.

I know I still have many shortcomings. In the future, I will constantly improve myself and strive to do the following:

1, consciously strengthen learning, learn from professional theoretical knowledge, learn from political theoretical knowledge, and learn from colleagues around you. Learn from each other's strengths and gradually improve their theoretical level and practical operation ability. Continue to learn boiler professional technology, improve accident handling ability, strive for more stable operation of the boiler, and make the boiler load reach a new high under the conditions of safety, stability and economy.

2, give full play to their own advantages, but also with other employees in the team to improve their operational skills, while doing their job well, with the continuous learning and skill level improvement, our work will be more arduous and demanding, requiring us to master higher and broader knowledge. To this end, I will work harder, study hard, strive to improve my cultural quality and work skills, and make contributions to the long-term safe and efficient operation of waste heat power generation.

The self-identification of boiler staff in power plant has been going on for three months, and I have been studying in the boiler post for almost three months unconsciously. During these three months, before going to bed every day, I asked myself how much I learned today, how much I really learned and how much I mastered. I really dare not slack off for a day. At first, Gong Fan told me that "people only have motivation when they are under pressure". Maybe it's the stress. The boilers outside have to bear this huge pressure all the time, and those of us who are engaged in the boiler industry naturally have to have pressure to do our work well and learn knowledge solidly. A little knowledge is not learning, and jokes about directing are endless. As long as you learn, you have to learn well.

At first, I was a little strange to boilers. With the passage of time, my understanding of boilers has gradually deepened. It is a groping process from being a layman in the past to slowly trying to apply what I learned in school to China. Sometimes I just memorize what I don't understand, and then use it slowly and timely, and then suddenly I remember, oh, that's the way it is, and the problem suddenly becomes clear. For example, at first I heard them say that torches should be used to light the fire. I was both curious and surprised. Why should such a big boiler be lit with torches? I learned later that it was just a joke. The real ignition does not need a torch, but an oil gun like a spear. When the oil pump produces great pressure, the oil will be sprayed into the furnace like a long snake and burned. ...

Circulatingfluidizedbedboiler (circulating fluidized bed boiler), whose English name is circulating fluidized bed boiler, continuously separates the ash from the furnace through cyclone separator, and then enters the furnace for combustion, which improves the combustion efficiency and saves the cost. Our power plant has two 75t/h boilers and one 130t/h circulating fluidized bed boiler, which is responsible for the steam supply and heat supply of almost the whole plant, with great responsibility. I remember General Manager Cui said: Honor and responsibility coexist. Although "burning the boiler" is a bit hard, because of the heavy honor behind a responsibility, the employees of our power plant have never complained and slacked off at all.

Gong Li is the section chief of the boiler department and also my section chief. From the beginning, I studied boilers, and Gong Li tried to help me get familiar with my post as soon as possible. In order to make me learn quickly, Gong Li personally showed me the whole boiler, from the coal-fired plant to the coal feeder, to the furnace and drum, and pointed out all the equipment I could see, and explained all the equipment I couldn't see carefully. Gong Li's eyes are always red, which I noticed from the beginning. After a period of getting along, I gradually understand that Gong Li is a very serious and good section chief. Every time he lights a stove, he has his own scenery, and every working class has his own busyness ... Gong Li's speech is also very humorous, which can make people laugh every time and give it to people after intense work.

I learned a lot from Li Gonggong. After three months of study, I have basically mastered the basic knowledge of boilers. From the initial installation of the boiler to the final normal operation, we have a general understanding of each step. After the boiler is installed, it has to go through an oven, which is to dry the pouring materials with high temperature flue gas, which I have never seen before. I heard the story that they started with a wooden oven. By adding a certain amount of alkali into the water, the rust or impurities in the boiler tube are removed by a boiling furnace, and then the boiler is ignited through a series of boosting and heating processes. If the newly installed steam falls down, you have to blow the pipe, that is, use high-pressure steam to blow away the welding slag and iron filings in the pipe to ensure the steam quality.

In addition to normal operation, I have also experienced several ignition, shutdown and maintenance. Through these work, I learned a lot from the section chief and colleagues. When you encounter problems, you must keep a calm heart and avoid being in a hurry. There are many preparations to be made before lighting the furnace. Check whether the instrument is normal, check the safety of the valve, and also check whether the oil level in the fuel tank, fan motor, coal feeder equipment, dcs instrument and other equipment are normal, and so on. We can't miss any of them. After all inspections are completed, start the vulcanization test, and record the vulcanization test results in detail as the basis for future fluidization. Turn on the induced draft fan first, then turn on the fan, and start feeding coal when the furnace temperature rises to about 450 degrees. When the bed temperature continues to rise to 900 degrees, turn on the secondary fan and open the quick air door ... step by step in strict accordance with the regulations, then boost the pressure and close the air door. When the steam drum pressure rises to the working temperature and pressure of 3.43mpa and 450 degrees, it will start to be combined with the furnace ... All these processes take about 5 minutes. If the middle goes well, it may save some time. Generally speaking, the time will be shorter in summer and slightly longer in winter because of the large temperature difference, so as to reduce the damage to the boiler caused by the stress caused by the temperature difference. During the overhaul, it was autumn. Although the temperature outside is not high, the temperature inside the furnace is not low. Wearing a sweatshirt makes you sweat. That is to say, I saw the structure of the furnace and the appearance of the water wall, as well as the small smoke hood, the sound of a hammer, the tireless work of the section chief and the work spirit of my colleagues in the power plant. All this is so real that I am deeply moved.

Time flies, I have been in the company for more than half a year, and it is a new year in a blink of an eye. Over the past year, the factory leaders have given careful guidance, and kind colleagues have helped me familiarize myself with the equipment and taught me the operation technology. In the new year, I can only do my job well, learn my knowledge well and report to them with fruitful results with a grateful heart.
