| 摘 要： | 气化岛是整体煤气化联合循环(integrated gasification combined cycle,IGCC)系统中较为复杂的关键单元,对整个系统性能有较大的影响。利用Thermoflex软件建立200MW级IGCC系统模型,从系统角度出发,对直接激冷式、除尘系统前带有气/气热交换器和取消气/气热交换器的3种IGCC系统进行比较,结果表明取消气/气热交换器的IGCC系统同样具有较高的效率,且系统更加安全可靠。对此系统中空分单元的氮气回注系数、气化炉单元的氧煤质量比,以及对流废锅出口粗合成气温度进行计算。计算结果表明:在空分系数为30%时,系统最佳氮气回注系数为70%;综合多种因素考虑,所研究煤种的最佳的氧煤质量比约为0.91;系统效率随着对流废锅(convective syngas cooler,CSC)合成气出口温度的增加而下降,当辐射废锅(radiant syngas cooler,RSC)粗合成气出口温度为700℃,对流废锅出口合成气温度取350℃,系统效率较高。

| Abstract: | The gasification island is a key and complicate unit in integrated gasification combined cycle (IGCC) system, and it affects the whole system performance greatly. The 200 MW IGCC system model was established using Thermoflex software, from the view of system, the IGCC systems with direct chilling, with and without gas/steam heat exchanger before dust removal were compared, the conclusions were obtained. That is, the IGCC system without gas/steam heat exchanger is much safer and has high system efficiency. T... |
