开发的集喷淋、水浴、水膜及冲击于一体的湿式净化器和横流侧位出气的气化反应炉组成的气化机组，具有燃气热值高、焦油含量低、安装方便、操作简单、安全可靠等特点。气化效率为78％，燃气低位热值为5.4MJ/m^3（玉米秸秆），焦油含量48mg/m^3,H2S为18.4mg/m^3，O2为0.7%，主要技术指标均超过同类机组。

Development of Stalks Gasification Unit with Wet Purge

An unit of stalks gasification is used to convert stalks and straws into fuel gas by biological technology. Then the fuel gas may be transported by a network of pipelines to individual user for cooking, heating, as well as power generation. The developed gasification unit in this work consists of a cross flow, lateral gas outlet gasifier and a wet cleaner which has the functions of sprinkling, water bathing, water film and swashing. The unit has the features of easy installation, simple operation, safty and reliability and can produce high quality fuel gas with higher heat value and lower tar content. Its gasification efficiency is as high as 78%, the low heat value of gas 5 4 MJ/m 3 , the tar content 48 mg/m 3, H 2S content 18 4 mg/m 3 and O 2 content 0 7%. All the major technical indexes are better than those of other kinds of gasification units.
