The closed furnace of smelting enterprises produces a large amount of surplus tail gas in the smelting process. After the tail gas is collected, cooled and purified, it can be used for combustion or internal combustion generator set to generate electricity. The ferroalloy tail gas mainly contains carbon monoxide and hydrogen, which needs to solve the problems of detonation and tempering when used for internal combustion generator set to generate electricity.

The industrial exhaust generator set is mainly developed for the gas with high carbon monoxide content. It is developed by new optimization and design on the foundation machine. The unit as a whole adopts modular design, distributing three modules of motor, engine and supercharging and cooling. The engine is placed in the middle, which is convenient for daily maintenance. Inlet and exhaust, and cooling water are concentrated at the free end, which is convenient for installation and layout of the power station.
engine adopts the shunt inlet double pressurization technology, which is specially developed for hydrogen-containing units. The structure is reliable and the operation is safe. The twin supercharger has been optimized and matched to provide efficient pressurization pressure for the engine and improve the operation power and efficiency of the unit.
