Gas generator can transfer coal into coal gas, and can make full use of coal, which is new type energy-saving equipment.

Coal Gas Producer/Coal Gasifier of Chinese Manufacture


Single Stage Coal Gasifier
Our single stage coal gasifier uses air and vapor as the gasifying agents to produce mixed gas. It is suitable for gasifying coking coal, hard coke, etc. And is widely used in machinery, metallurgy, chemistry, glass, building materials, food, textile and light industries.

Our single stage coal gasifier features low investment, good applicability, convenient use, easy operation, etc. Compared with direct coal burning, coal gasifier can save 20% of the fuel. Compared with oil furnace, coal gasifier can save more than 60% of the energy. Our coal gasifier is environment-friendly with its heat efficiency and good dust and smoke removal effect.


Working Principle
Solid coal can be gasified into inflammable gases through vapor media. This coal gas is then roughly de-dusted and conveyed through a conveying pipe to burn at a nozzle. The heat produced is used to heat the thermal furnace. With the gas as the burning material, the temperature is even on the furnace. Our single stage coal gasifier is widely used as steel rolling furnace, annealing furnace, forging furnace, steel pipe furnace, glass furnace, aluminum furnace, melting furnace, cooper furnace, pottery furnace, etc.
