We independently develop a series of gas-fired units, using lean combustion technology to achieve overall electronic control of gas-fired units. The gas-fired units can use natural gas (CNG, LNG), liquefied petroleum gas (LPG), oilfield associated gas, coalbed methane (gas), and biogas, and are widely used in oil and gas fields, coal mines, landfills, farm biogas power generation, factory power stations, mining power supply combined heat, power, and cooling projects, and other civil fields. Our product spectrum covers a power range of 10kW-4000kW.
With advanced lean combustion technology, high-energy ignition, and a Venturi mixer, the natural gas power generation efficiency can reach >3.7kw.h/m³.
Through optimized intake and exhaust duct designs, all cylinders perform evenly and smoothly. This significantly lowers cylinder and exhaust temperatures, maintaining the exhaust temp in front of the turbine at only 600±10°C, extending service life by 2 to 3 times compared to industry averages.
Custom configurations are available upon request.
