Gas (coalbed methane) generator set is a gas generator set that uses low concentration gas and high concentration gas for power generation. The gas generator set produced by Jinan Watt can generate electricity using gas with a concentration greater than 12%, mainly used for coal mine gas and mine gas power generation. The unit adopts a new gas engine design concept, independently developed, and utilizes advanced whole machine development systems, matched with world-class boosting, speed regulation, voltage stabilization, ignition, and operation management systems. It integrates cutting-edge patented combustion control, electronic control mixer and other technologies in the industry, and can automatically control the air-fuel ratio to adapt to changes in gas concentration, which is suitable for the characteristics of China’s coal mines with multiple points and small quantities. The unit has the characteristics of high safety, high reliability, high thermal efficiency, high cost-effectiveness, and fully automated operation and management.
