【Abstract】 This paper has summarized the research achievements on characteristics of combined cycle system of IGCC in all operating states.On the base of the conception of independent variables,the paper has analyzed the factors,which influence the offdesign behavior of IGCC system,and constructed a characteristic atlas frame in all operating states.The offdesign characteristics of gasside subsystem and steamside subsystem of IGCC in different regulation modes have been revealed.Based on lots of calculations,the characteristic atlases of combined cycle system of IGCCin all operating states have been mapped out.The performance variations of IGCC system with load and atmospheric temperature have been summed up and some valuable conclusions have been obtained.All these research achievements will provide the specific information and effective method for further study on operation,control and design of IGCC System.更多还原
