Introduction of Coal Gasifier
Coal gasifier is one of the high production capacity and high gasification efficient gasifier. It is used to convert the combustible matter into a combustible gas which could utilize the industrial gas and heat various furnaces or the products directly.
The equipment is suitable for gasifying coking coal, coke and other fuels, are widely used as furnace kiln of machinery, metallurgy, chemical industry, glass, building materials, light industry, food, textile industry.
It is used to convert the combustible matter into the combustible gas which could utilize the industrial gas and heat various furnaces or the products directly. The coal gasifier has the characteristics of high yield, high efficiency, convenient to operate and with better adaptability, etc.
Features of Coal Gasifier
1. Flexible – can operate in air-blown or oxygen-blown mode.
2. Lower energy consumption – less oxygen consumption than slagging gasifiers
3. Low-cost proprietary refractory with long life.
4. Lowest water use – excellent fit for sites with limited water resources
5. Convenient to remove slags, easy to operate and maintain.
6. Have a significant effect of smoke prevention and dust control, meet environmental protection requirements.
Working principle of Coal Gasifier
When the fuel of coal is into the furnace by the coal machine, reacts with gasifying agent (air + water vapor) by the lower part of the drum, then the gasification happen, and along the bed height direction from bottom to top, there are five layers: the ash layer, oxide layer, reduction layer, carbonization layer, drying layer.
1. Ash layer: the coal come down from the top, the gas agent go up from the bottom.
2. Oxide layer: also called burning layer, thermal chemical reaction, the O with heat in the air reaction to become CO2, release heat.
3. Reduction layer: the coal after heat and together with steam complex reaction become to CO, H2, CH4, O2, CO2, N2 etc, and release heat.
4. Carbonization layer: under 400-500,the volatile and other materials come out, the coal become to coke, the coke come to the reduction layer for chemical action.
5. Dryer layer: to dry the coal gas.
