Product details
Gas generators reduce costs and increase profits due to energy conservation, and meet environmental standards due to gas operation. In the context of increasing energy prices and stricter environmental requirements, using a gas generator is your best choice.
Two stage gas generators are mainly used as fuel for heating furnaces in metallurgy, building materials, and glass industries, as well as raw materials and fuels in the chemical industry.
-
The calorific value of coal gas is high, and the coal is thoroughly distilled in the furnace. The lower section of coal gas does not contain tar.
-
High degree of mechanization, hydraulic coal feeding and slag removal, stable equipment operation.
- Coal has strong adaptability, especially suitable for bituminous coal with high tar content and high gas production.
- Small footprint, high gas production, no sewage pollution, and low long-term operating costs.
