Renovation Of 300MW Steam Turbine In Sanhe Power Plant

China's "thirteen five" energy plan,the total energy consumption to control the 4.8 billion tons of standard coal around the total coal consumption control of about 4.2 billion tons,the proportion of coal consumption control in 62% to 2020 year.Thermal power plant is a large energy consumption.Saving energy,reducing consumption and the survival and development of enterprises are inseparable.It is very important for thermal power companies that educing power generation costs and improving the economy of enterprises.Coal consumption is one of the most critical factors to limit the cost of thermal power plants.According to the thermal economic analysis of thermal power plants,an important factor in the high energy consumption of power plants is that the efficiency of steam turbine flow is relatively low.So the steam turbine flow through the transformation of a large number of major energy-saving technological transformation projects,has become an important measure to improve the thermal efficiency of generating units.This paper takes the # 4 unit of Sanhe Power Plant as the research object,it describes the equipment status of the unit before the flow through the transformation and some of the main problems,and the importance of the unit flow transformation analysis,and then related to the corresponding The transformation of the program,principles and content..In this paper,the thermal performance test data of the unit after the transformation of the unit were studied accordingly,further analysis of the operating conditions in different operating conditions of the unit,and for this feature,but also put forward a deep level of energy saving recommendations and measures.
