基于一种顶喷式干煤粉气化炉有效气含量影响因素的探究

摘要

为达到最高的有效气含量(CO+ H2) ,结合一种顶喷式干煤粉气化炉的实际运行情况,在烧嘴类型和气化炉尺寸一定的条件下,对氧煤比、入炉蒸汽、煤粉载气、环隙吹扫气、点火烧嘴燃料气等有效气的含量影响因素进行了探究,探明了最佳的反应条件,可为同类顶喷式干煤粉气化条件的优化提供参考.%In order to achieve the maximum effective gas content (CO+ H2) ,this paper explores the factors affecting the effective gas content , such as O2-to-Coal ratio ,steam entering gasifier ,carrier gas of pulverized coal ,purge gas of annular space and fuel gas of startup burner on condi-tion that the burner type and gasifier dimension are fixed .It ascertains the best reaction condition ,which can serves as reference for the condition of dry pulverized coal gasification of overhead spray .
