One Yuchai 12VCN 1000kW gas‑fired generator set was equipped and put into operation at a coal‑mine gas power station in Zhaotong, Yunnan Province. The unit takes extracted coal‑mine methane as fuel to generate on‑site power for mine production and auxiliary facilities.
1.Background:
Zhaotong Coal Mine Gas Utilization Project Coal resources are abundant in Zhaotong Yunnan. Large volumes of coal‑mine methane are drained during underground coal mining. Direct venting of methane creates safety risks and heavy greenhouse‑gas emissions. This gas‑to‑power project converts drained mine gas into usable electricity. The generated power supplies key mine loads including underground ventilation, gas drainage systems and workshop utilities. Surplus power can be fed into the local public grid. The mine site faces typical mountain‑mine conditions: fluctuating methane concentration, high dust and humidity, which place high requirements on gas adaptability and continuous running reliability for gas generator equipment.
2.Why the 1000KW 12VCN Gas‑Fired Unit
This single 1000kW Yuchai 12VCN gas unit serves as the core power equipment for the station. The 12‑cylinder V‑type gas engine is specially optimized for unstable coal‑mine methane quality. It maintains stable combustion output when gas composition and methane content fluctuate frequently. The whole system adopts anti‑dust and anti‑corrosion reinforcement treatment for air intake pipeline and control cabinet, adapting to dusty humid mountain mine environment. Modular skid‑mounted structure simplifies field installation, commissioning and routine overhaul work.
3.Key Technical Specifications
‑ Engine: Yuchai 12VCN, 12‑cylinder V‑type gas engine (×1) ‑ Rated Power: 1000 kW ‑ Configuration: skid‑mounted, parallel‑capable ‑ Fuel: extracted coal‑mine methane / coal‑mine gas ‑ Rated Speed: 1000 r/min ‑ Rated Frequency: 50 Hz ‑ Control: intelligent gas adaptive control system, multi‑parameter safety interlock protection ‑ Note: reinforced anti‑dust & anti‑corrosion treatment for mountain coal‑mine working conditions
4.Operational Value Since Commissioning
Since commissioning, this Yuchai 12VCN gas generator set has effectively reused waste coal‑mine methane for power generation. It reduces methane greenhouse‑gas emission and cuts the mine's purchase cost of grid power, achieving notable circular‑economy benefits. Reinforced anti‑dust and anti‑corrosion design copes well with local mountain‑mine harsh conditions and extends service life of core components.
5.Frequently Asked Questions (FAQ)
Q: What fuel does this Yuchai 12VCN unit burn?
A: It runs on extracted coal‑mine methane. The intelligent control system is optimized to handle real‑world on‑site methane‑concentration fluctuation.
Q: Can this unit work under high‑dust humid mountain mine environment?
A: Yes. Special anti‑dust filtering, cabinet sealing and anti‑corrosion coating treatments are adopted for mountain mining site conditions.
Q: Can this generator connect to public power grid?
A: Yes. With parallel function available, surplus generated power can be fed into local power grid according to project requirements.
Q: Is expansion possible for this power station later?
A: Yes. More same‑type 1000kW gas units can be added, and multiple units can operate in parallel to expand total installed capacity.
