瓦斯（主要成分为甲烷）是煤矿安全生产的“头号杀手”——瓦斯爆炸是煤矿非常严重的事故类型之一。然而，在瓦斯发电机组面前，这个“隐形杀手”却被驯服为“绿色电神”。瓦斯发电机组通过将抽采的煤矿瓦斯转化为电能，实现了“化害为利、变废为宝”。

Gas (mainly composed of methane) is the "number one killer" of coal mine safety production - gas explosion is one of the most serious types of accidents in coal mines. However, in front of the gas generator set, this "invisible killer" was tamed as the "green electricity god". The gas generator set converts the extracted coal mine gas into electrical energy, achieving the goal of "turning harm into benefit and waste into treasure".

瓦斯发电的核心挑战在于瓦斯浓度的不稳定性。煤矿瓦斯具有浓度低、压力波动大、成分复杂、含水量高等特性，这给发电机组持续稳定运行带来大挑战。传统发电机组在瓦斯浓度达到12%时才能启动、13%以上才能并网发电，浓度7%-13%之间的瓦斯只能无效排空。为解决这一行业难题，淄柴新能源通过系统集成创新，将数字化、智能化技术植入发电机组模块——机组内置50多个灵敏传感器，实时采集并传输数据至控制系统，能够自动调节以适应燃气浓度与压力的波动。

The core challenge of gas power generation lies in the instability of gas concentration. Coal mine gas has the characteristics of low concentration, large pressure fluctuations, complex composition, and high water content, which poses great challenges to the continuous and stable operation of power generation units. Traditional generator sets can only start when the gas concentration reaches 12%, and can only be connected to the grid for power generation when the gas concentration exceeds 13%. Gas concentrations between 7% and 13% can only be effectively discharged. To solve this industry problem, Zichai New Energy has integrated digital and intelligent technologies into the generator module through system innovation. The unit is equipped with more than 50 sensitive sensors that collect and transmit data in real time to the control system, which can automatically adjust to adapt to fluctuations in gas concentration and pressure.

在技术突破方面，新一代瓦斯发电机组实现了低浓度瓦斯的有效利用。鸡西矿业公司隆昇发电公司对发电机组进行升级改造后，实现了瓦斯浓度7%-8%即可发电。宁夏煤业汝箕沟瓦斯发电站采用全球优良的低浓度瓦斯控制燃烧技术，通过实时检测氧气含量实现自动控制空燃比，解决了传统发电机组难以应对瓦斯状态多变的问题。

In terms of technological breakthroughs, the new generation of gas generators has achieved effective utilization of low concentration gas. After upgrading and renovating the generator units, Jixi Mining Company's Longsheng Power Generation Company has achieved power generation with a gas concentration of 7% -8%. The Rujigou Gas Power Station of Ningxia Coal Industry adopts the world's leading low concentration gas control combustion technology, which automatically controls the air-fuel ratio through real-time detection of oxygen content, solving the problem of traditional generator units being unable to cope with the changing gas state.

在工程实践方面，瓦斯发电的效益十分可观。鸡西矿业公司隆昇发电公司2025年完成瓦斯发电5000余万度。金驹煤电化公司南苏18MW分布式瓦斯发电项目已开工建设。瓦斯发电站将煤矿抽采的瓦斯转化为清洁电力，既保障了煤矿安全生产（降低井下瓦斯浓度），又创造了经济效益，实现了安全与效益的双赢。

In terms of engineering practice, the benefits of gas power generation are very considerable. Jixi Mining Company Longsheng Power Generation Company will complete gas power generation of over 50 million kilowatt hours by 2025. The 18MW distributed gas power generation project of Jinju Coal and Electricity Company in Nansu has started construction comprehensively. Gas power stations convert the gas extracted from coal mines into clean electricity, which not only ensures coal mine safety production (reduces underground gas concentration), but also creates economic benefits, achieving a win-win situation of safety and efficiency.
