Refining and chemical production enterprises such as shale oil, blue coke, coke, calcium carbide and ferroalloy will produce a large amount of low calorific value industrial tail gas in the production process. These combustible gases are mainly composed of hydrogen and carbon monoxide, with complex composition, many impurities, unstable composition, high toxicity, flammability and explosion. Except for the self-use of a small number of refining and chemical plants, most of the rest are burned and exhausted.

For this kind of gas, based on the gas internal combustion engine, a high-power gas generator unit with a power range of 500-1200kW has been developed, which is suitable for coke oven gas, producer gas, coke tail gas, oil shale tail gas, carbide tail gas, ferroalloy tail gas and other industrial tail gas. The utilization of these combustible coke oven gas for power generation can not only solve the air pollution caused by emissions, but also save power resources.

 

Hydrogen and carbon monoxide gas have strong adaptability and wide application range;      

 

Good resistance to impurities such as tar, dust, sulfur and naphthalene in refining gas;

 

Air is mixed with gas cylinder, high hydrogen gas has no flashback problem and high safety;      

 

Automatic adjustment of air-fuel ratio, strong adaptability to gas fluctuations, and stable power output;

 

High degree of automation, with one-button start, automatic closing, loading and other functions;      

 

Long annual operation time, low failure rate, long maintenance cycle and low operation cost;
