5 MW/hr (24 hours) Cold Coal Gasification to Power Generation for Captive Consumption

​​

Bituminous coal is lifted to the coal storage bin by lifting system; the coal is added in the carbonation stage of two-stage coal Gasifier by a programmable control feeding system. Air is blown in the bottom of furnace by air blower, at the same time, low pressure steam goes through the blending bin and blends with air, becomes the gasification agent, which will carry on the gasification reaction with 1200 Celsius degree semi coke in the gasification stage.

Producer gas is made by the gasification agent, which is mixture of steam and air, which goes through red-hot fixed burning bed. The oxygen content in the air and steam react with the carbon in the fuel; generating the producer gas with has ingredients like CO, CO2,H2,CH4,C2H4, N2 etc.
