摘要

在1MW循环流化床热电气多联产试验装置上进行了循环煤气热解半焦燃烧的试验研究。试验结果表明

循环煤气煤热解燃烧多联产方案可以产生(12~14)MJ/m3(标准状态)中热值煤气

但在气化炉中燃料转化率只有30%~40%

大部分燃料在燃烧炉中燃烧;气化炉温度对煤热解反应和燃烧炉运行影响较大;随着Ca/s摩尔比的增加

硫化氢浓度和焦油含量显著降低。

Abstract

Test study of recyclic coal gas pyrolysis semi-tar combustion has been carried out on a 1 MW circulating fluidized bed(CFB) test facility for realizing co-generation of heat

electricity

and gas.Test results show that:the coal gas with middle calorific value(12~14)MJ/m3(standard state) can be produced by the co-generation scheme with recyclic coal gas pyrolysis combustion

but the fuel conversion rate in gasifier is only 30%~40%

and most of fuel having been burnt in the combuster;the temperature in gasifier greatly affects the coal pyrolysis reaction and the operation of combuster;the concentration of H2S and tar content are substantially reduced along with increase of Ca/S molar ratio.
