DIAGNOSIS AND ANALYSIS OF ENERGY-SAVING IN TYPICAL THERMODYNAMIC SYSTEM
A simple and convenient diagnosis method of energy-saving has been put forward,and the analysis and calculation being carried out by using the performance test data and the turbine's structural data.The operation performance diagnosis of flow passage in steam turbine,as well as of heat regeneration system,feed-water pump,small steam turbine,desuperheating water,shaft seal system,condenser,pressure loss of the extracted steam,loss of steam and water,and all parameters in operation has been carried out for a typical 330 MW unit,and the energy loss distribution diagram being given.The diagnosis shows that the total deviation of heat consumption for all factors is 448.25 kJ/kWh,tallying well with the designed value and tested value.
