Research On Energy Loss Analysis Method In Thermal Power Plants Economic Analysis

Power plants consume a lot of energy,mainly coal-based energy, which also led to higher levels of emissions of pollutants. In response to the national call for “energy-saving and emission-reduction”, “energy saving” has become a top priority under the premise of safe operation of the unit. Coal-consumption is the final economic indicators of thermal power plants,how to reduce coal-consumption as much as possible and make the unit operating under optimum environment has become a very important issue for many experts and scholars.Thermal power units have been difficult to keep running at design conditions, mostly in variable parameter operation state, so discuss thermal economy of thermal power plants that running in varying working conditions has become an important prerequisite in the issue of “energy saving”. This paper introduces a method of thermal economic analysis in the unit which running in varying working conditions, namely loss analysis method.Firstly,this paper introduces the concept of energy loss analysis methods. The second section describes the methods and procedures of thermodynamic calculation of thermal power units in variable condition. Then, through energy savings assessment calculations in condensate choke project of 600 WM direct air-cooling unit, this paper detailing the principle of loss analysis method and specific modeling and analysis process. Finally, this paper describes the thermal economics- line monitoring and analysis system of power plant, including the main function modules and subsystems display interface, discusses the application of loss analysis method in power plant operation optimization of economic management, lays the foundation for economic and efficient operation of thermal power units.
