Abstract
Considering the heat value of blast furnace gas and coke oven gas in domestic steelworks,the existing gas fuel with low heat value for gas turbine cannot meet the market demand,thus the reduction of heat value is further required.However,the fuel mass is greatly raised with heat value reduction,so modification of the compressor is necessary to lower the flow mass.Based on the prototype compressor,optimization of the flow path and blades was carried out from aspects of flow mass reduce,surge margin raise,etc.,and with the design idea of"tip cut and blade optimization",the compressor flow mass was reduced by 10%,and the surge margin was improved by more than 12%.The research results can provide reference for similar retrofit design of subsequent units.关键词
