In practical applications, low concentration gas power generation requires several core technologies to support the smooth progress of the entire power generation process, such as reliable flame retardant technology, fully electronic control technology, electronically controlled gas mixer technology, digital ignition technology, and gas air mixed turbocharging technology. In the whole unit system, the safety of operation and gas transmission must be ensured first, so safe and reliable flame arresters need to be set. Different types of flame arresters need to be installed respectively in the main air intake pipe of the power station, the main air intake pipe of the unit, the gas pipeline in front of the mixer, between the Intercooler and the supercharger, and between the speed regulating throttle of the air intake pipe.

另外，在瓦斯輸送時(shí)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(cháng)度和輸送瓦斯規模等多方面因素決定。

In addition, when transporting gas, 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 placements is determined by various factors such as the length of the transmission pipeline and the scale of the gas transmission.

電控燃氣混合器技術(shù)，簡(jiǎn)言之，就是通過(guò)電工藝與技術(shù)子控制技術(shù)來(lái)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(shù)則是需要增壓器和中冷器來(lái)促進(jìn)瓦斯空氣的混合效果和混合比例，提高發(fā)電機功率并降低產(chǎn)生的熱負荷。發(fā)電技術(shù)在不斷改善，目前點(diǎn)火技術(shù)上多用電控單元來(lái)根據實(shí)際情況調控點(diǎn)火時(shí)間、點(diǎn)火強度等，確保點(diǎn)火操作處于的環(huán)境中。

In short, the technology of electrically controlled gas mixer is to adjust the mixing ratio and air-fuel ratio of gas mixture through electrical process and technical sub control technology, while the technology of gas air mixed pressurization requires supercharger and Intercooler to promote the mixing effect and mixing ratio of gas air, increase the power of generator and reduce the generated heat load. The power generation technology is constantly improving. 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.

低濃度瓦斯發(fā)電技術(shù)經(jīng)研發(fā)和不斷創(chuàng )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(fā)電優(yōu)勢，其他還有鍋爐與蒸汽輪機發(fā)電模式、燃氣輪機與蒸汽輪機發(fā)電組合模式。在使用瓦斯發(fā)電時(shí)，燃氣內燃機式發(fā)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(jīng)濟效益高和混合氣發(fā)火范圍廣等絕對性?xún)?yōu)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, and other power generation modes include boiler and steam turbine power generation mode, gas turbine and steam turbine power generation combination mode. When using gas for power generation, the gas internal combustion engine power generation mode has absolute advantages such as complete combustion, less harmful gas emissions, good anti knock performance, high economic benefits, and a wide range of mixed gas ignition.
