Coalbed Methane for Efficient Power Generation

Coalbed Methane

Most coal mines contain significant amounts of coal mine gas and abandoned mine methane, which can be effectively harnessed for electricity and heat generation. The robust utilization of coal mine gas for power generation not only conserves energy and reduces emissions but also transforms potential hazards into valuable resources. This approach enhances safety in coal mining operations and lowers greenhouse gas emissions, resulting in substantial economic, environmental, and social benefits.

LIYU'S Coalbed Methane Solutions

After undergoing dehydration, dust removal, boosting, and stabilization, the gas is transported to the Liyu gas-specific generator set for fuel operation. This process drives the piston, allowing the gas engine to generate electricity, while the waste heat produced can be utilized for heating.

The Main Types Of Coalbed Methane

Coalbed methane is a type of gas found in coal seams, primarily composed of CH₄. It can be classified into three categories:
 

• Coalbed Methane: This is the gas extracted directly from coal seams, often with a CH₄ content of 95-99%, making it highly pure.
• High-Concentration Gas: This gas contains 30-60% CH₄ and is relatively simple in composition, primarily consisting of methane with minor amounts of air (N₂ and O₂) and few other impurities.
• Low-Concentration Gas: With a CH₄ content of less than 30%, this gas typically has around 5-20% CH₄, with the remainder being air.
