Abstract
This paper mainly discusses the performance state evaluation method and optimization technology of gas-steam combined cycle unit.Taking the unit of a gas power plant as the research object,the internal efficiency of gas turbine,the internal efficiency and cycle heat efficiency of steam turbine and the waste heat utilization ratio of waste heat boiler are selected to evaluate the performance of gas turbine,steam turbine and waste heat boiler.The results show that the performance of gas turbine and steam turbine is stable,and the performance of waste heat boiler decreases obviously.Based on the further analysis of the flue gas data and water vapor data of the waste heat boiler,it is considered that the decline of the performance of the evaporator is the main reason for the decline of the performance of the waste heat boiler,and on this basis,optimization strategies such as installing flue gas filter and optimizing the structure of transition flue are put forward.As a result,the performance of the unit can be restored well.关键词
