Two sets of Yuchai 12VCN 1000kW gas‑fired generator sets are officially put into operation at the Quanlun Gas Power Station in Bijie City, Guizhou Province. Driven by on‑site drained coal mine gas, the twin units with a total installed capacity of 2000kW provide stable and reliable power supply for local mine production systems, underground ventilation equipment, gas drainage facilities, safety monitoring devices and daily auxiliary power systems. The project effectively realizes harmless treatment and efficient resource recycling of abandoned mine gas, reducing methane emissions and enabling the mine to achieve green, low‑carbon and safe production.
1. Background: Bijie Quanlun Coal Mine Gas Utilization Project
Bijie is an important coal energy base in western Guizhou with abundant coal mine gas resources and complete gas extraction and supporting infrastructure. Large quantities of coal mine gas are continuously generated and drained during coal mining. Direct emission of untreated coal mine gas results in massive waste of clean energy, increases greenhouse gas emissions, and brings major safety hazards to the mining area. As a key local green energy recycling project, the Quanlun gas power project aims to convert waste coal mine gas into clean electric energy. The generated electricity prioritizes on‑site mine power consumption, with surplus power connected to the public grid. The local mining environment features unstable gas concentration, high humidity and fine mine dust, which impose strict requirements on the gas adaptability, dustproof performance, corrosion resistance and continuous operation stability of generator equipment.
2. Why Adopt 2×1000KW Yuchai 12VCN Gas‑Fired Units
The dual Yuchai 12VCN 1000kW gas generator sets serve as the core power equipment of Bijie Quanlun Gas Power Station. Featuring a professional 12‑cylinder V‑type gas engine, the units are specially optimized for the variable coal mine gas characteristics of Guizhou mining areas. They stably adapt to frequent gas concentration fluctuations, maintaining efficient combustion and stable rated power output under complex and variable working conditions. The whole machine adopts upgraded dust filtration, full sealing and anti‑corrosion technologies. Air intake systems, internal pipelines and core control components are specially treated for dust and humidity resistance, effectively coping with the high‑humidity and dusty mining environment in Bijie. With integrated skid‑mounted design, the units feature compact structure, convenient on‑site installation and commissioning, and low operation and maintenance costs, fully satisfying the long‑term, high‑stability and high‑reliability operation requirements of the mine gas power station.

4. Operational Value Since Commissioning
Since official commissioning, the two Yuchai 12VCN 1000kW gas generator sets have achieved full resource utilization and harmless disposal of coal mine gas for the Bijie Quanlun project. The units greatly reduce local methane emissions and environmental pollution, lower the mine's dependence on municipal grid power, and significantly cut enterprise power operation costs. With excellent environmental adaptability and ultra‑stable continuous operation performance, the equipment effectively reduces failure rates and extends the service life of core components. The project delivers stable economic benefits, outstanding environmental value and solid safety guarantees for the green and low‑carbon development of local coal energy industry.
5. Frequently Asked Questions (FAQ)
Q: What fuel do the Yuchai 12VCN units adopt for power generation in the Bijie Quanlun project?
A: The units operate with on‑site drained coal mine gas as fuel. Equipped with an intelligent gas adaptive control system, they can automatically adjust combustion parameters in real time to adapt to unstable gas concentration under complex mine working conditions, ensuring continuous, efficient and stable power generation.
Q: Can the units adapt to the humid and dusty working environment of Guizhou coal mines?
A: Yes. The units adopt customized high‑efficiency dust filtration structure, full sealing design and high‑performance anti‑corrosion coatings. They can operate stably in high‑humidity, dusty and complex mining environments with strong environmental adaptability and anti‑aging performance.
Q: Do the 1000kW units support grid‑connected power generation?
A: Yes. The units support grid parallel operation. The generated electricity can be used for mine self‑consumption, and surplus power can be fed into the local public grid to maximize clean energy utilization efficiency.
Q: Does the power station support subsequent capacity expansion?
A: Yes. The project reserves expansion space. More Yuchai 12VCN 1000kW units can be added for parallel operation to increase total installed capacity and meet the growing power demand of mine production and operation.
