Traditional CHP Solution During coal mine production, the drainage gas pumped up from the drainage station with a methane concentration of more than 8% is used as fuel to generate electricity after simple processing. The generated power can be integrated into the internal coal mine network or directly into the national grid. The high-temperature exhaust smoke of the engine passes through the exhaust heat recovery device, and the recovered heat energy can be used for heating, bathing, and underground hot air delivery in winter.
Technical advantages of Zichai series gas-fired generator sets
▪ The low-concentration gas water mist transportation system has multi-level protection functions of fire prevention, explosion venting, explosion suppression, and explosion-proofing to ensure the safety of low-concentration gas transportation;
▪ Using electronically controlled mixer and closed-loop automatic control technology, the air-to-air ratio can be adjusted in real time, with strong adaptability to gas fluctuations and stable power output;
▪ The unit can operate continuously at full load, with an annual operating time of up to 7,500 hours, and high power generation income;
▪ Equipped with one-button start, automatic closing and loading functions, with a high degree of automation; ▪ The unit failure rate is low, the overhaul cycle is long, and the operating cost is low.
Gas source requirements: Gas should be processed before entering the machine to meet the following requirements:
01
Inlet gas temperature
Inlet gas temperature ≤40℃; Inlet gas temperature ≤40℃;
The gas gas generator set has a wide range of power, adapting to the characteristics of low gas concentration and large gas source fluctuations in coal mines. The low-concentration gas generator set has outstanding advantages and is currently widely used in major coal mines in China.
