One set of Yuchai 12VCN 1000kW gas‑fired generator set is officially put into operation at the Huigui Gas Power Station in Zunyi City, Guizhou Province. Driven by on‑site drained coal mine gas, the unit delivers stable and continuous power supply for local mine production systems, underground ventilation equipment, gas drainage facilities and daily auxiliary power systems. The project effectively realizes harmless treatment and efficient resource recycling of abandoned mine gas, helping the mine achieve green, low‑carbon and safe production.

1. Background: Zunyi Huigui Coal Mine Gas Utilization Project
Zunyi is a key coal energy base in northern Guizhou, with abundant coal mine gas resources and mature gas extraction and supporting infrastructure. A large volume of coal mine gas is continuously generated and drained during coal mining operations. Direct emission of untreated coal mine gas not only causes serious waste of clean energy resources, but also brings greenhouse gas emissions and potential safety risks to the mining area. As a key local green energy recycling project, the Huigui gas power project focuses on turning waste gas into valuable power. It converts drained coal mine gas into clean electric energy to support on‑site production power consumption, with surplus electricity accessible to the public power grid. The local mining environment features fluctuating gas concentration, high humidity and fine industrial dust, which raise stringent standards for the gas adaptability, corrosion resistance, dustproof performance and long‑term continuous operation stability of generator units.
2. Why Adopt 1000KW Yuchai 12VCN Gas‑Fired Unit
The Yuchai 12VCN 1000kW gas generator acts as the core power equipment for the Zunyi Huigui gas power station. Adopting a professional 12‑cylinder V‑type gas engine, the unit is specially optimized for the variable and complex characteristics of coal mine gas in Guizhou mining areas. It can perfectly adapt to frequent fluctuations in gas concentration, maintaining stable combustion efficiency and consistent rated power output under variable working conditions. The whole unit is equipped with upgraded dust filtration, sealing and anti‑corrosion technologies. The air intake system, internal pipelines and core control components have undergone targeted anti‑dust and anti‑humidity corrosion treatment, effectively resisting the harsh impact of high humidity and mine dust in local mining environments. Featuring an integrated skid‑mounted design, the unit has a compact overall structure, convenient on‑site installation and commissioning, and low daily operation and maintenance costs, fully meeting the long‑term, stable and high‑reliability operation requirements of mine gas power stations.
