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，在瓦斯输送时不仅需要保证输送管道不漏气、不易燃，还需配置细水雾输送装置。安置数量由输送管道长度和输送瓦斯规模等多方面因素决定。

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.

电控燃气混合器技术，简言之，就是通过电工艺与技术子控制技术来调节混合气的混合比例和空燃比，而瓦斯与空气混合增压技术则是需要增压器和中冷器来促进瓦斯空气的混合效果和混合比例，提高发电机功率并降低产生的热负荷。发电技术在不断改善，目前点火技术上多用电控单元来根据实际情况调控点火时间、点火强度等，确保点火操作处于的环境中。

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.

低浓度瓦斯发电技术经研发和不断创新之后在我国大部分煤矿中得到应用，在其所有应用形式中，燃气内燃机式发电优势，其他还有锅炉与蒸汽轮机发电模式、燃气轮机与蒸汽轮机发电组合模式。在使用瓦斯发电时，燃气内燃机式发电模式具有燃烧充分完全、排放有害气体少、抗爆燃性能好、经济效益高和混合气发火范围广等绝对性优势。

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.
