One set of Yuchai 12VCN 1000kW gas-fired generator set is officially applied to the coal mine gas power station of Jiaozuo Coal Industry, Henan Province. Powered by onsite drained coal mine methane, the unit provides stable and continuous power supply for mine production equipment, underground ventilation, gas drainage systems and daily auxiliary facilities, realizing efficient recycling utilization of mine waste gas resources.
1. Background: Jiaozuo Coal Mine Gas Utilization Project
Jiaozuo is an important traditional coal industrial base in Henan with complete coal mining and gas extraction infrastructure. Large amounts of coal mine methane are continuously drained during mining operations. Direct emptying of methane causes serious environmental pollution, greenhouse gas emissions and potential safety hazards. This gas-to-power project effectively converts waste coal mine gas into clean electric power. The generated electricity supports core mine production loads, while surplus power can be connected to the local public grid. The local mining environment features unstable methane concentration, humid air and fine mine dust, which put forward strict requirements on gas adaptability, anti-corrosion performance and long-term continuous operation of gas generator units.
2. Why Adopt 1000KW Yuchai 12VCN Gas-Fired Unit
The Yuchai 12VCN 1000kW gas generator serves as the core power equipment for this Jiaozuo mine gas power station. Equipped with a 12-cylinder V-type gas engine, the unit is professionally optimized for variable coal mine methane quality. It adapts well to frequent fluctuations of methane concentration and maintains stable combustion and consistent power output under complex working conditions. The whole machine adopts upgraded anti-dust and anti-corrosion treatments for air intake systems, pipelines and control components, effectively resisting mine dust and humid corrosion. The integrated skid-mounted structure features compact layout, convenient on-site installation, simple commissioning and low daily maintenance cost, perfectly matching long-term stable operation demands of mine power stations.
