Traditional CHP solutions 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 coal mine's internal 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.
ZichaiTechnical advantages of gas 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.
Air source requirements Gas should be treated before entering the machine to meet the following requirements:
01
Inlet gas temperature
The inlet gas temperature is ≤40℃; The inlet gas temperature is ≤40℃;
Gas pressure 2.5~10kPa; Pressure change rate ≤1kPa/min;
Methane volume content ≥8%, The total content of methane and oxygen is ≥26%; Oxygen volume content ≥16%;
03
Dust content, dust particle size
Dust content ≤30mg/Nm3; Dust particle size ≤5μm; The total sulfur content is ≤50mg/Nm.
The power range of gas-fired generator sets is wide, adapting to the characteristics of low gas concentration and large gas source fluctuations in coal mines. Low-concentration gas generator sets have outstanding advantages and have been widely used in major domestic coal mines.
