The following is a summary of energy saving and consumption reduction in enterprises that I have compiled for you. Welcome to read it. For more related content, please pay attention to the work summary column. Summary of energy-saving and consumption-reducing work in enterprises

What is the current era? Energy consumption? As an important index to evaluate the comprehensive competitiveness of an enterprise, this confirms a simple and profound truth, and energy consumption index has increasingly become an important driving force for the sustainable development of a country and an enterprise. Since Ningbo Zhongmao Hangzhou Bay Thermal Power Co., Ltd. was put into production in 2xx, the leaders of the company have attached great importance to energy saving and cleaner production, and established a leading group for energy saving management and cleaner production with the general manager as the team leader.

with the strong support of the company's leaders, all employees actively participated. The company started with technical energy saving and management energy saving, set up a scientific development concept, comprehensively investigated, analyzed and studied the production status, and determined the energy-saving key points and transformation projects. After technical transformation, the operation reliability and safety of the equipment were greatly improved, and the energy-saving effect was remarkable. 2xx In July, our company was listed as a pilot unit of energy-saving and cleaner production audit in Ningbo by Ningbo Economic Commission and Ningbo Environmental Protection Bureau, and passed the cleaner production audit and acceptance.

1. Improve the management network and constantly improve the system to ensure energy conservation and consumption reduction organizationally

In order to strengthen the scientific management of energy conservation and promote the in-depth and lasting development of energy conservation, a leading group for energy conservation management and cleaner production with the general manager as the team leader was established. An energy-saving network, which is under the responsibility of the deputy general manager of production and attended by department directors, relevant technicians, squad leaders or team technicians, has been set up, and a task force for energy conservation has been set up to implement the policies, laws and regulations related to energy conservation and various rules, regulations and rules of technical supervision on energy conservation. Further improve the system of energy-saving technical supervision standards and incentives for energy-saving technical measures, so that energy-saving technical supervision can be followed and energy-saving management can be further standardized.

at the same time, around the company's overall goal, the energy-saving work plan was formulated at the beginning of the year, and it was broken down monthly. Conduct energy-saving network activities and analysis of main economic indicators and small economic indicators every month. While summarizing the work of last month, organize, coordinate, decompose and implement the problems existing in production and economic indicators, which further improves the overall energy-saving awareness of enterprises.

second, the mass energy-saving work is carried out in depth, and the awareness of energy-saving is further enhanced

The energy-saving work covers a wide range, involving every corner and everyone in the company. On the one hand, the company conducts external training and invites cleaner production consultants to give class training to production backbones and various management personnel, and comprehensively learn the knowledge of energy-saving production and cleaner production, and have a heated discussion. On the other hand, we fully mobilize employees, rely on the wisdom and strength of employees, distribute learning brochures such as energy-saving production and cleaner production-oriented catalogues to employees, and organize team-based learning. At the same time, we use computer platforms to exchange our learning experiences, and also make a large-scale report on energy-saving and cleaner production. In addition, special questions and answers on energy-saving and cleaner production knowledge and rationalization suggestions were arranged, and publicity slogans on energy-saving and cleaner production were hung in eye-catching positions of each team.

through the activities, the company formed a good energy-saving production atmosphere, improved the ideology of energy-saving and clean production of all employees, made the production backbone and important post personnel have a clear understanding of energy-saving and clean production, and created favorable conditions for carrying out energy-saving and clean production. The company actively mobilized all employees to carry out rationalization proposals with the theme of energy saving, consumption reduction, pollution reduction and efficiency improvement. Three hours? Activities, in carrying out rationalization proposals, not only focus on large energy-saving projects, but also make minor changes and save money bit by bit.

Third, relying on science and technology to highlight the key points, grasping the key points, seeking truth from facts and reducing energy consumption

Energy consumption will cause environmental pollution, and energy conservation will be the most effective means to slow down and control pollution. We rely on science and technology to save, rely on science and technology to create benefits, persist in saving energy and reducing consumption to survive and promote development; From the aspects of standardized management and equipment renovation, we should improve the safety, reliability and operation economy of equipment, think big, start small, and start from me bit by bit. In the process control of energy-saving and clean production, advanced energy-saving technologies and equipment are mainly adopted:

1. Frequency conversion and other speed regulation technologies are adopted, such as frequency conversion speed regulation and hydraulic coupling speed regulation for induced draft fan, secondary machine and coal conveying system motor. After variable frequency speed regulation is adopted in induced draft fan, soft start is realized, which avoids the damage of impact torque to the motor when the high-power motor is started. At the same time, the motor speed can be adjusted smoothly according to the boiler working conditions, the air volume can be controlled, the throttling loss can be reduced, the electric energy consumption can be saved, and the thermal efficiency of the boiler can be improved.

2. The circulating water softening treatment and on-line non-stop circulating water large-scale system cleaning, sterilization, scale inhibition and pipeline dredging are adopted to improve the heat exchange benefit of condenser, heat dissipation benefit of cooling tower and vacuum of unit. After treatment, the vacuum is increased by 4kpa, and the coal consumption for power generation is reduced by about 1 g/kWh.

3. Transform the flow passage of the steam turbine, clean and adjust the static and dynamic clearance, improve the thermal efficiency of the steam turbine, increase the output of the unit and reduce the coal consumption.

4. adopt a circulating fluidized bed boiler with high efficiency, energy saving and environmental protection, and adopt flue gas desulfurization technology inside and outside the furnace; At the same time, strengthen operation regulation, actively carry out small index competition activities, improve boiler combustion conditions and steam turbine operation parameters, and make the boiler and boiler run more economically. The coal consumption and auxiliary power consumption are reduced. The thermal efficiency of that boil is improved, and the emission of cinder and dust is reduce.

5. The steam turbine feed water pump is used instead of the electric feed water pump to improve the utilization efficiency of self-owned steam and reduce the auxiliary power consumption rate.

6. adopt new thermal insulation materials such as rare earth with good thermal insulation performance to insulate the boiler and main steam pipes;

7. The boilers and turbines adopt dcs automatic control technology, and the electrical equipment adopts comprehensive relay protection, automatic switching and automatic control technology;

8. Use back pressure turbine instead of extraction condensing turbine to reduce condensing loss and coal consumption for power generation.

9. Reduce the loss of steam water, such as implementing measures such as recovering qualified water quality after leakage detection of condenser pressure water, regulating regular blowdown of boiler, controlling the opening of continuous drainage, and maintaining the operation of continuous drainage level to reduce the loss of steam water. At the same time, strengthen equipment management, try to eliminate internal and external leakage of thermal system, and strive for no leakage.

1, actively carry out total quality management activities, improve the original equipment, in order to achieve the purpose of energy saving; For example: design and install the steam seal condensate (desalted water) recovery device by yourself; Improvement of chemical water treatment process; Automatic hydrophobic modification of high pressure heater; The operation of oil purification device and oil filter regeneration equipment, etc. We * * * implemented 41 energy-saving and cleaner production schemes with no/low cost and 11 high-cost schemes in terms of equipment production technology.

after the implementation of the scheme, the emissions of energy, raw and auxiliary materials and wastes have been greatly reduced, which can achieve a reduction of sulfur dioxide emissions by 26, soot emissions by 32, standard coal consumption for power generation by 13 and auxiliary power consumption by 19? 5. The total thermal efficiency is increased by 24? The energy consumption of 5, yuan output value decreased by 27%, which achieved good environmental and economic benefits for the company.

energy conservation is a long-term strategic policy for the country's economic development, an important index for evaluating the comprehensive competitiveness of an enterprise, and an eternal subject. Energy conservation and consumption reduction have a long way to go. We will, as always, do a good job in energy conservation and consumption reduction, and make plans for sustainable energy conservation and cleaner production, so that energy conservation and cleaner production can be carried out in an organized and planned way throughout the company. Summary of energy conservation and emission reduction

Since the beginning of this year, our bureau has systematically arranged the ideas, methods, objectives and measures for promoting energy conservation and emission reduction. In order to further strengthen the responsibility, do a good job of implementation, combined with the spirit of energy conservation and emission reduction in Sheng City, convene a mobilization meeting for key energy-consuming enterprises, implement the spirit of energy conservation and emission reduction in the whole country and Sheng City, further clarify the objectives and tasks of energy conservation and emission reduction, strengthen the responsibility, pay close attention to implementation, and earnestly do a good job in energy conservation and emission reduction.

according to the provincial target responsibility requirements for energy conservation and emission reduction, and in combination with the specific situation of our city, it was decided by the party group of our bureau that the key units for energy conservation and emission reduction of township enterprises in xx were: Zihenghua Silicon Industry Co., Ltd., Tianma Cement Factory in Baiyun Town, Pingba County, Zihongtai Chemical Co., Ltd., Zichengxiang Cement Factory, Guanling County Jiachang Zhongshui Electrochemical Industry Co., Ltd., Puding Jiaqi Cement Co., Ltd. and Pingba County Phosphating Factory No.8. And signed a target responsibility letter with the enterprise that the energy consumption per unit product decreased by more than 4 over the previous year. Since the beginning of this year, the energy conservation and emission reduction work of township enterprises in our city is summarized as follows:

1. Since earnestly studying and exchanging experiences to carry out energy conservation and consumption reduction activities, cities and counties (districts) have seriously organized target-responsible enterprises to study in the pilot units that carried out energy conservation and emission reduction last year, and the pilot units are invited to introduce the experience of energy conservation and consumption reduction and the achievements of technological transformation. Through mutual exchanges and learning between enterprises, key energy-saving and emission-reduction enterprises set up energy-saving and consumption-reducing offices in combination with the actual production and operation of their own enterprises, and the factory director in charge of production takes the lead in taking overall responsibility, leading and coordinating, and supervising the promotion according to the target division of labor.

do a good job in the planning outline and annual targets, implement technological transformation and energy-saving projects, eliminate backwardness in a timely manner, use policy incentives to mobilize the enthusiasm of all health departments and all those who are conducive to energy conservation and emission reduction, and clarify the full-time staff to implement them. Ziyun Henghua Silicon Industry Co., Ltd. and Pingba Tianma Cement Factory also allocated special funds for energy conservation, consumption reduction and emission reduction, formulated operating procedures according to production links, and trained employees in batches for energy conservation and consumption reduction, and implemented specific work requirements for energy conservation and emission reduction from basic management. Focus on strengthening production technology, quality improvement and site management, reducing the consumption of raw materials and power, especially grasping all links in the consumption of electricity, raw coal and water, so as to increase production and save money.

By taking effective measures to save energy and reduce consumption, the comprehensive utilization level of resources has been improved, and the total consumption of resources has shown a downward trend. From January to July, the comprehensive energy consumption of the pilot units for energy conservation and consumption reduction decreased by 6 to 4.xx-xx percentage points respectively; The total industrial output value increased by 17 and 21 respectively.

II. Main measures to carry out energy conservation and emission reduction

In the process of energy conservation and consumption reduction, key energy conservation and emission reduction units in our city have mainly taken the following measures:

(1) Clear objectives and actively promote energy conservation and consumption reduction.

after the enterprise has made clear the goal of energy saving and consumption reduction. Take the initiative to contact relevant departments such as science and technology and environmental protection. It has given strong guidance, supervision and control on pollution control and emission reduction, and promoted the implementation of technical measures for emission reduction; Standardize technical standards for energy conservation and emission reduction, guide standardized operations, and promote energy conservation and emission reduction of technological progress; Highlight the supervision and elimination of high energy-consuming equipment, and apply new technologies and equipment to promote energy conservation and emission reduction of process equipment. To study and put forward the main work direction and measures for enterprises to carry out energy saving and consumption reduction.

solve the key problems in production, further improve the coordination mechanism between processes in enterprise departments, and strengthen the mutual coordination and organizational leadership of production work. At the same time, through the training and guidance of front-line workers in production, the work of saving energy and reducing consumption is ensured to be implemented.

(2) pay attention to on-site management and improve the product qualification rate.

from the field management, there are weak links in energy-saving management, whether in the field of production, circulation or consumption. Since the implementation of energy conservation and consumption reduction, enterprises have strengthened the registration system of material and energy consumption accounts in every production link, and linked the assessment with benefits and wages for production teams. At the same time, focus on ensuring the safety of the production line, achieve continuous operation, and reduce the loss of shutdown and maintenance; Actively explore and improve the process, put an end to the phenomenon of leakage and reduce the consumption of raw materials and energy.

since the energy conservation and emission reduction work was carried out this year, the cement industry has been mainly engaged in minor technical transformation, which has increased unit output, reduced energy consumption and reduced the rate of equipment shutdown and maintenance; The chemical industry should organize production and allocate personnel scientifically, make full use of energy, reduce consumption, strengthen the control of raw material consumption in the production process, and do a good job in production inspection and quality tracking; Ferroalloy industry completely replaces old equipment by introducing advanced environmental protection facilities and resource integration, and reduces the consumption of coal, electricity and water.

relying on advanced technology to save energy, reduce pollution and increase efficiency; Pay attention to source control, pay attention to process energy conservation, constantly improve metering facilities, and initially build a statistical, supervision and assessment system for energy conservation, pollution reduction and efficiency improvement. All energy conservation and emission reduction targets and responsibilities strengthen the management of raw material procurement, do everything possible to improve the quality of raw materials, reduce processing energy consumption, increase unit output and increase enterprise benefits.

(3) Strengthen the independent innovation of enterprises and promote the development of circular economy.

in order to promote the development of energy conservation and consumption reduction, and promote enterprises to improve economic growth, quality improvement and efficiency growth. In the technological transformation of energy conservation and emission reduction, enterprises have increased their investment in the application of their own technologies, and their own innovative technologies have played a significant role in the transformation and upgrading of traditional industries. Eliminate backward equipment and production technology, improve the competitiveness of enterprises, and save energy, reduce pollution and increase efficiency from the source. It has promoted enterprises to increase the innovation ability of their own technologies and the introduction and application of advanced and applicable technologies, improved the energy efficiency of major energy-consuming equipment and reduced the energy consumption per unit product.

in order to make the key consumption items get reasonable comprehensive utilization of resources, enterprises have classified and identified some raw materials that meet the comprehensive utilization of resources, reduced energy consumption from the source, reduced the generation of pollutants, strengthened the comprehensive utilization of resources, reasonably promoted the extension of industrial chain, promoted the integration of products, maximized the utilization of various wastes and renewable resources, and improved the efficiency of resource utilization. Special attention is paid to strengthening the comprehensive utilization of metallurgical slag and surplus energy waste heat, supporting massive optimization, greening and beautifying the environment, realizing pollutant emission reduction, and obviously improving the regional living environment. The construction of circular economy has achieved phased results.

III. Problems

The situation of energy saving and consumption reduction in our city is still not optimistic. It is difficult for enterprises to save energy and reduce consumption. On the one hand, although most high-energy-consuming enterprises have carried out energy-saving and consumption-reducing work well, business operators have paid more attention to it, but what measures enterprises should take to save energy and reduce consumption can not find a reasonable plan, especially in the transformation of old equipment, enterprises have almost no corresponding technical ability and financial guarantee. Although operators also want to introduce advanced technology to reduce electricity consumption, coal consumption and water consumption, increase production and increase efficiency.

However, due to the lack of funds, the investment of enterprises in energy-saving technologies is obviously insufficient. On the other hand, due to the lack of expert guidance for energy-saving technologies promoted in the market, enterprises lack enthusiasm for application and promotion. At the same time, enterprises often have problems such as low production management level and low skills of employees, which have brought certain difficulties to enterprises' energy saving and consumption reduction. These problems have brought great difficulties to the further promotion of energy saving and consumption reduction.

IV. Suggestions on energy conservation and consumption reduction and plans for the next step

In order to effectively promote the development of consumption reduction, continuously improve product quality and enhance the competitiveness of enterprises in the market, it is essential to transform the necessary production processes and absorb advanced technologies. It is suggested that the provincial bureau first increase the investment of support and guidance funds in energy conservation and emission reduction, and properly arrange and implement energy conservation funds. The second is to strengthen the promotion of new technologies, establish corresponding technical service institutions, and strengthen the training of special operators and technicians.
