摘　　要：围绕IGCC技术发展趋势与热点,针对不同配置流程的F级IGCC热力系统模拟和计算,得出各系统方案总体性能参数,比较不同配置流程的F级IGCC系统在热力性能上的差异。研究结果表明：F级IGCC系统净输出功率达350~450 MW,采用湿法气化、激冷流程的系统供电效率为38%左右,采用干法气化、显热回收流程的系统供电效率为48%左右;带CO2捕捉符合低碳经济的发展趋势,但集成捕捉装置后IGCC热力性能下降明显,F级IGCC供电效率下降8百分点以上;＂二拖一＂IGCC方案相比单机方案热力性能提高,且有益于单位造价的降低,符合大规模IGCC系统的发展方向。Based on the development tendency of IGCC technology,different types of IGCC systems with F class gas turbine were studied and simulated,during which the overall performance parameters were obtained while their thermal performance was compared among different types of system schemes.Study results show that the net output of F class IGCC system is within 350~450 MW,and its net efficiency is around 38% under wet gasification with quenching process,which is around 48% under dry gasification with sensible heat recovery process.IGCC system with CO2 capture process accords with the trend of low carbon economy,but the thermal performance declines dramatically after the integration of capture device,and for F class IGCC system,the degree of decline is up to 8 percent.The thermal performance of F class IGCC system with two-pull-one combined cycle is better than the one-pull-one type,and the two-pull-one type IGCC is beneficial to the reduction of unit cost,conforming to the development direction of large scale IGCC systems.
