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.
Features
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.
Double Stage Coal Gasifier
The working process of double stage coal gasifier consists of carbonization and gasification. During carbonization process, coal goes through intensive drying and low temperature carbonization, and gradually turns into semicoke. During the gasifying process, hot semicoke reacts with gasifying agent and turns into ash, which is discharged from ash bowl automatically.
In low temperature carbonization process, dry distillation gas is produced by evaporating water content. It is used as top gas of double stage coal gasifier and takes up 40% of the total gas amount. Dry distillation gas enjoys higher heat value (6700KJ/nm3) and low temperature (120° C), and contains large amount of tar, which is produced by low temperature carbonization. Tar is of good liquidity and can be gathered by electrostatic dust collector as chemical raw materials and fuels.
During gasifying process of the double stage coal gasifier, hot semicoke and gasifying agent conduct a series of chemical reactions including reduction and oxidation and produce gasified gas.
