低濃度瓦斯發電技術經研發和不斷創新之后在我國大部分煤礦中得到應用，在其所有應用形式中，燃氣內燃機式發電最具優勢，其他還有鍋爐與蒸汽輪機發電模式、燃氣輪機與蒸汽輪機發電組合模式。在使用瓦斯發電時，燃氣內燃機式發電模式具有燃燒充分完全、排放有害氣體少、抗爆燃性能好、經濟效益高和混合氣發火范圍廣等絕對性優勢。

After research and continuous innovation, low concentration gas power generation technology has been applied in most coal mines in China. Among all its application forms, gas internal combustion engine power generation has the most advantages, while other power generation modes include boiler and steam turbine power generation, and gas turbine and steam turbine power generation combination mode. When using gas power generation, the gas internal combustion engine power generation mode has absolute advantages such as complete combustion, less emission of harmful gases, good anti knock performance, high economic benefits, and a wide range of mixed gas ignition.

低濃度瓦斯發電在實際應用中需要幾種核心技術來支撐整個發電過程的順利進行，如可靠性高的阻火技術、全電子控制技術、電控燃氣混合器技術、數字式點燃技術以及瓦斯與空氣混合增壓技術等。在整個機組系統中

Low concentration gas power generation requires several core technologies in practical applications to support the smooth progress of the entire power generation process, such as high reliability flame retardant technology, fully electronic control technology, electronic control gas mixer technology, digital ignition technology, and gas air mixed boosting technology. Throughout the entire unit system,

要保證運行和氣體傳輸的安全性，因此需要設置安全可靠的阻火器，在發電站總進氣管、機組進氣總管、混合器前的燃氣管線、中冷器與增壓器之間及進氣管調速節氣門間都需分別安裝不同類型的阻火器。另外，在瓦斯輸送時不僅需要保證輸送管道不漏氣、不易燃，還需配置細水霧輸送裝置。安置數量由輸送管道長度和輸送瓦斯規模等多方面因素決定。

To ensure the safety of operation and gas transmission, it is necessary to install safe and reliable flame arresters. Different types of flame arresters need to be installed separately in the main intake pipe of the power plant, the main intake pipe of the unit, the gas pipeline in front of the mixer, between the intercooler and the booster, and between the speed regulating throttle valve of the intake pipe. In addition, during gas transportation, it is not only necessary to ensure that the conveying pipeline is not leaking or flammable, but also to equip a fine water mist conveying device. The number of installations is determined by various factors such as the length of the transmission pipeline and the scale of gas transmission.

電控燃氣混合器技術，簡言之，就是通過電工藝與技術子控制技術來調節混合氣的混合比例和空燃比，而瓦斯與空氣混合增壓技術則是需要增壓器和中冷器來促進瓦斯空氣的混合效果和混合比例，提高發電機功率并降低產生的熱負荷。發電技術在不斷改善，目前點火技術上多用電控單元來根據實際情況調控點火時間、點火強度等，確保點火操作處于最佳的環境中。

Electric control gas mixer technology, in short, is to adjust the mixing ratio and air-fuel ratio of the mixed gas through electrical process and technical sub control technology, while gas and air mixed boosting technology requires a turbocharger and intercooler to promote the mixing effect and mixing ratio of gas and air, increase generator power, and reduce the generated heat load. Power generation technology is constantly improving, and currently, electronic control units are commonly used in ignition technology to regulate ignition time, ignition intensity, etc. based on actual conditions, ensuring that ignition operations are in the optimal environment.
