摘要

为了研究煤与生物质共气化条件下多联产系统能量利用特性与煤炭节省率

建立了煤与生物质共气化并联型FT合成油-IGCC多联产系统。进料量为3 000 t/d

FT合成侧合成气分流比设为0.2、0.4、0.6、0.8。结果显示:当生物质掺混质量分数为0.2时

在每一个设定的分流比下系统均能获得最大热效率

分别为46.39%、46.51%、46.59%、47.49%。生物质质量分数小于0.2时

在每个设定分流比下具有较优的煤炭节省率;生物质质量分数超过0.2时

FT合成侧合成气分流比对煤炭节省率影响更为明显。因此

在特定生物质质量分数下可通过增加FT合成侧合成气分流比来提高多联产系统煤炭节省率。

Abstract

To study the energy utilization characteristics and coal saving ratio of multi-generation system under cogasification of coal and biomass

a coal-biomass co-gasification parallel FT synthetic oil-IGCC co-production system was established. The feedstock is 3 000 t/d and the syngas shunting ratio at the FTS side is assumed as 0.2

0.4

0.6

0.8

respectively. The results show that

when the biomass mass ratio of the feedstock is 0.2

the polygeneration system can obtain the highest thermal efficiency(46.39%

46.51%

46.59%

47.49%) at each assumed shunting ratio. When the biomass mass ratio is smaller than 0.2

the coal saving ratio is higher at each assumed FTS shunting ratio. When the biomass mass ratio is larger than 0.2

the syngas shunting ratio at the FTS side has an obvious effect on the coal saving ratio. Therefore

at specific biomass mass ratio

the coal saving ratio of the polygeneration system can be improved by increasing the syngas shunting ratio at the FTS side.
