2014 Yuhong 3.2m Two stage hot gas coal gasifier from the sodium silicate smelting!

Description of the Two stage hot gas coal gasifier

Double stage coal gasifier(diameter 2m,2.6m,3.2m,3.4m,3.6m,4m,gas output from 200Nm3/h to 14,000Nm3/h). Two-Stage Coal Gasifier is specially designed for the gasification of bituminous coal with higher gas heat value than that of single-stage coal gasifier and it has good environmental protection performance. Tar is removed from coal in the pyrolysis to form free flowing light oil, which can be recycled with extensive application.

Put the 40~60mm coal into the coal bin by the lifting equipment, and then the program controlled coal feeder charging the coal into the double stage gasifier . The air blower blowing the mixed air and steam as the gasification agent, from the air and steam mix chamber at the bottom of the gasifier.

The gasification agent reacted with 1200°Ctemperature semicoke at the gasifying section of the gasifier,

and generated the combustible gas.The component of the gas is CO is about 31~33%, H2 is about 9~10%, CH4 is about 0.4%~0.5% meanwhile at the carbonize section of the gasifier,

utilize the waste heat of the down stage gas make the carbonizing to generate CO is about 29~31%.H2 is about 17~19%

CH4 is about 1~3%, CnHm is about 0.2~0.4% combustible gas.The coal gas temperature of the carbonization section is around 100~150C,

the gas flow through the electric detarrer to get rid of the dust and tar,and then flow into the gas main. The water and tar gathered from the bottom of the detarrer was sending to the tar tank.

The coal gas temperature of the gasifying section is around 550~600°C,

flow through the cyclone dust catcher to removing the big granular dust, and then flow into the gas main.

The two stage gas was combined at the gas main, and its temperature is around 150~250C. The hot gas removing tar technology takes full advantage of the sensible heat of the gas.And it is a good choice for there is less demanding for the gas cleanness requirement.
