Sichuan Coal Group introduces GE turbines for generating power using coalbed methane
Thread Content
China Sichuan Coal Group recently installed two GE Energy Group Yan** gas internal combustion engines that have been certified as green innovation products. These two GE units will generate electricity using coalbed methane for use in coal mining, as an important measure in China’s efforts to reduce greenhouse gas emissions derived from methane in its coal mines. According to relevant sources, the gas power plant operated by China Chuanmei Group Furong Coalbed Methane Utilization Company is located in Xunchang Town, Gongxian County, about 40 kilometers away from Yibin City in Sichuan Province. Each generator unit has a capacity of 3.048 megawatts. At the same time, the exhaust gases from the GE turbines will be used to generate steam, which in turn drives steam turbines to produce additional electricity. The gas power plant of China Sichuan Coal Group Furong Coalbed Methane Utilization Company, which uses coalbed methane for power generation, has GE-powered units, and trial operations are scheduled to begin by the end of March this year.

At present, the Sihe coalbed methane power generation project of Shanxi Jincheng Coal Industry Group is the largest gas power generation project in the world. The power plant is equipped with 60 Caterpillar diesel generators, each with a capacity of 1.8 MW; these are arranged in four units, with 15 generators in each unit. Each unit is fitted with three waste heat boilers capable of handling 5.625 t/h of heat, as well as one steam turbine generator with a capacity of 3 MW. Additionally, the cooling water used to cool the engine cylinders is utilized for centralized heating at the Sihe Coal Mine through heat exchange. The total installed capacity is 120 MW, with an annual power generation of around 840 million kWh. The annual gas consumption, in terms of pure methane, amounts to 178.7 million cubic meters, which is equivalent to a reduction of 2.77 million tons of carbon dioxide emissions.
