%X 建立200 MW级整体煤气化联合循环(IGCC)发电系统模型,以整体性为原则,基于各设备单元的物质平衡、能量平衡以及化学反应平衡对IGCC系统进行计算,探讨不同汽水循环形式、不同余热锅炉与废热锅炉汽水配置方式对IGCC发电系统性能的影响。结果表明:在本研究系统中,选择三压再热汽水循环形式,可进一步回收燃气轮机的排气余热,同时提高了汽轮机的初参数,有利于提高系统性能;余热锅炉高压省煤器的汽水配置遵循"温度对口、能量梯级利用"的原则,以获得较高的整体性能。研究结果为同级别IGCC系统中常规岛的优化设计提供参考。 The 200 MW integrated gasification combined cycle(IGCC) system model was established and calculated.Complied with principle of integrity,influences of different steam-water cycle modes and different matching schemes of HRSG with waste heat cooler on overall performance,local thermal characteristics in IGCC were discussed according to mass balance,energy balance and reaction equilibrium of each unit.The results show that three-pressure reheat steam-water cycle mode is beneficial to recycle waste heat of exhaust from gas turbine,to increase main steam parameters of steam turbine,and to boost overall performance in IGCC.Reasonable matching scheme of HRSG with waste heat cooler is designed according to principle of "temperature matching and step utilization of energy".The research results can provide references for optimization design of conventional island in equivalent level IGCC system
