摘要

针对某新型顶部多喷嘴气流床气化炉

通过物理建模方法建立了该气化炉的数学模型

运用非预混燃烧方法分析了热态运行条件下该炉与单喷嘴气流床气化炉差异

以及变工况条件下该炉合成气成分及温度分布变化规律。结果表明:较单喷嘴气流床气化炉

该炉具有更均匀的流场分布特性和更高的有效成分含量;变工况运行时

随着副喷嘴倾角增大

合成气中有效成分减少

合成气温度降低;随着主喷嘴物料流量比例增大

合成气中有效成分呈先增加后减小趋势

合成气温度逐渐增大。

Abstract

Mathematical model of a new multi-burner entrained flow coal gasifier was established to predict its fluid flow distribution.In this model

non-premixed combustion method was applied to compare the flow field properties of this new coal gasifier with that of the single burner gasifier

and analyze the changes of coal gas component and temperature under varying load conditions.The simulation results show that

compared with the single burner gasifier

the new coal gasifier had more uniform flow field distribution and higher available components content.Under varying load conditions

as the auxiliary burner inclination angle rose

the available components content decreased and the syngas temperature dropped.With an increase in the feed stock flow proportion in main burner

the available components content in syngas increased first and then decreased

while the syngas temperature increased gradually.
