Heat Balance Calculation And Optimization Analysis Of Igcc Steam Cycle Sub-System

IGCC (Integrated Gasification Combined Cycle) promises to provide a large share of the future world energy needs in an economical, reliable, and environmentally-friendly way. In order to analyze the influence of steam condition on IGCC pelformance for a given gas turbine system, IGCC system efficiency and steam turbine output were studied in this paper. Based on a three-pressure reheat HRSG system heat balance model, optimization model of IGCC steam cycle sub-system is established via Matlab. Results indicate that HP drum pressure, reheat steam pressure and etc are important steam parameters which influence IGCC thermodynamic performance. In addition, the variation law of IGCC system was simultaneously analyzed
