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.

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,

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.

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.
