Analysis of energy saving and consumption reduction measures for steam turbine operation in power plant

China is a big energy consuming country. With the increasing pressure of environmental protection and the consumption of non-renewable resources, reducing consumption and increasing efficiency is the mainstream direction of steam turbine research and development. The following measures for energy saving and consumption reduction of steam turbines in power plants are analyzed. Welcome to read and browse.

1 Operation Status of Steam Turbine in Power Plant

(1) As early as the 20th century, China began to study the transformation of steam turbines. After so many years of exploration, the power plant in China has been separated from the old steam turbine and transformed into a more advanced one. However, the energy available in today's society is getting less and less, and the energy consumption of steam turbines is still not a small amount, so China must still devote itself to the reform of energy saving and consumption reduction of steam turbines.

(2) China is a big energy consumer. With the increasing pressure of environmental protection and the consumption of non-renewable resources, reducing consumption and increasing efficiency is the mainstream direction of steam turbine research and development. At the same time, China has also invested huge sums of money to cooperate with foreign countries or exchange markets for technology to introduce advanced foreign technologies. However, there is still a gap between China's steam turbine level and foreign technology. The fundamental reason is that we mostly imitate, and the ability to absorb and transform core technologies and the ability to develop and innovate technologies on this basis are insufficient.

(3) The overall quality and education of power plant personnel in China are not enough. In domestic factories similar to power plants, employees are not well educated, and R&D is generally ignored, which leads to the limited capacity of R&D related science and technology departments. Therefore, it is relatively difficult to solve the problem of energy saving and consumption reduction of steam turbines, which is also the reason why some power plants have been in the bottleneck.

(4) Most domestic power plants are installed and maintained by themselves. After testing, these devices have some shortcomings, and there is still a big gap with the international standard energy-saving and consumption-reducing equipment. Therefore, it needs to be improved in all aspects, imitating the energy-saving and consumption-reducing technologies of developed countries in the world, so as to improve the domestic technology.

(5) The management system of the power plant is not rigorous enough. One of the major drawbacks of our factory is that it attaches importance to economic benefits, but lacks a unified and efficient management system. Therefore, the staff of the power plant have no enthusiasm and cannot devote themselves to reforming the production of steam turbines. This is why the steam turbines in power plants in China are not very developed so far.

2 power plant steam turbine energy consumption reasons

(1) Steam turbine is the main equipment for power generation in power plants, and its overall structure is very complicated. In operation, its efficiency is easily affected by other factors, such as exhaust back pressure. Various reasons lead to the increase of energy consumption in steam turbine operation.

(2) During operation, the steam turbine operation is not standardized, resulting in changes in various parts of the steam turbine. This improper operation will lead to overload, which will increase the energy consumption of steam turbine. In the process of use, there is also a constant startup and shutdown, which is also one of the reasons for high energy consumption.

3 power plant steam turbine energy saving measures

(1) In the past twenty years, China has been devoted to the research of power station science and technology. Although we have made great achievements compared with before, we still can't achieve the best results. Therefore, China should learn from foreign science and technology, take its essence, discard its dross, take its strengths and apply them to China's power plants, and choose several large-scale and fast-developing power plants to use first. If the result is good, it will work.

(2) The current economic situation in China is not suitable for copying the development strategies of western countries. According to our own development status, we should give full play to the advantages of steam turbines in power plants in China, compare our shortcomings with those in western countries, sum up our shortcomings, and finally learn from them to develop China's energy-saving and consumption-reducing cause at the fastest speed.

(3) For power plant employees, it is necessary to improve their quality in a unified way. It is necessary to regularly train on-the-job employees, explain the benefits of energy saving and consumption reduction to the country, factories and individuals, and subtly influence employees' attention to energy saving and consumption reduction. For newly recruited personnel, strengthen the assessment, and take energy saving and consumption reduction of steam turbines as a more important category in the assessment.

(4) The state should strengthen the training of energy-saving and consumption-reducing talents in colleges and universities. Some Chinese people do not realize the benefits of energy saving and consumption reduction. Therefore, it is necessary to focus on cultivating talents in this field in colleges and universities, so that more professionals in this field can invest in the work of power plants in the future and make great contributions to the development of power plants in China.

(5) The state should strengthen the management of power plants, revoke the right to use self-assembled equipment in some power plants, publicize the shortcomings and hazards of self-assembled equipment to power plants, and advocate the use of relatively perfect steam turbines installed by the state, which is also a good way to save energy and reduce consumption [5].

(6) The power plant should also relatively reform the management system and strength of employees, punish employees who are usually lax in discipline and don't work hard, and assign special personnel to check whether the site safety and the use of machines are standardized, and educate employees who do not turn off the machines according to the formal workflow or switch them on and off at will, so as to improve the consciousness of employees on site, improve the service life of machines and save energy and reduce consumption.

(7) After overcoming other objective factors, we should also start with technology to optimize the operation process of steam turbines in power plants, reduce power generation costs and improve power generation efficiency. At the same time, it is necessary to ensure the safe operation of the steam turbine and not blindly carry out technological innovation. We should carry out reform step by step on the original basis, and we should not seek quality just because our technology is backward or our energy consumption is high. In this way, even if the effect of energy saving and emission reduction is achieved, there will be great shortcomings in other aspects. At the same time, we should pay attention to the absorption and transformation of imported advanced technology, otherwise it will be tangible without mastering its core technology, and it will not promote the development of steam turbine technology in China. Ensuring safety and advancement is the research direction of energy saving and consumption reduction technology for steam turbines in power plants in China in the new period.

4 conclusion

To sum up, controlling the energy loss of steam turbines is one of the most important tasks of power plants, and its operating efficiency is closely related to the benefits of power plants. Therefore, in practice, we should choose appropriate methods and means to discuss the operation mode of steam turbine from the perspective of power plant itself, with the emphasis on combining with reality. Take different measures from multiple links, fully discover and make use of the characteristics of steam turbines in our factory to carry out related operations, and finally achieve the purpose of energy saving and consumption reduction.
