摘要：基于ASPEN PLUS软件模拟平台,对生物质与煤气流床共气化过程进行模拟,考察操作条件及生物质与煤配比变化对气化性能的影响。模拟计算结果表明:与生物质单独气化相比,生物质与煤共气化能提高气化温度及气化效率;与煤单独气化相比,生物质可部分替代煤且不会明显改变气化效果,尽管气化温度略有下降,但混合物灰熔点的降低能很好弥补这一变化。生物质质量分数为20%,[O]/[C]摩尔比在1.1～1.3时气化效果最佳,气化温度约为1250℃,有效气产率1.92Nm^3/kg,煤气热值可达到11.5MJ/Nm^3,冷煤气效率79.7%。
Based on ASPEN PLUS, the entrained-flow co-gasification of biomass and coal was simulated. The results showed that on the one hand, compared with biomass gasification alone, the co-gasification temperature and efficiency in- creased, on the other hand, compared with coal gasification alone, the gasification efficiency did not changed greatly when coal was partly replaced by biomass. Though the gasification temperature decreased, the ash fusion point of mixture of biomass and coal also decreased. The gasification result is optimum when the mass fraction of biomass is 20 % and the molar ratio of oxygen to carbon is arrange from 1.1 to 1.3. The gasification temperature is above 1250℃ ; the effective gas productive rate is 1.92Nm^3/kg; the caloric value of syngas is 11.5MJ/Nm^3 ; the cold gas efficiency is 79.7%.
