GE Jenbacher Supplies Cogeneration Systems To German, Ukrainian Coal Mine Gas Projects
25 May 2004 09:54
GE Jenbacher, a division of GE Energy, is developing two of the largest coal mine gas plants of their type in the world, one in Germany, the other in Ukraine.
GE Jenbacher has provided 14 cogeneration systems to Europe's largest coal mine gas plant, located in the district of Fenne near Saarbrücken, Germany. The JMS 620 GS cogeneration systems, the largest manufactured by GE Jenbacher, produce more than 40 megawatts of electricity and nearly 41 megawatts of thermal energy at the Fenne operation, which is owned by SaarEnergie.
The Fenne station's annual production capacity of 350,000 MWh of both electrical and thermal energy is able to meet the requirements of 80,000 households.
The Fenne mine gas plant offers significant economic features, with a total efficiency of 84.4% (42.1% electrical, 42.3% thermal). The electricity is fed into an industrial grid and the heat is supplied to a district heating system.
Fenne is now also Europe's largest gas engine-powered combined heat and power (CHP) plant to be subsidized under the European Renewable Energies Act.
Meanwhile, GE Jenbacher is also providing 22 complete gas engine cogeneration systems for a Ukrainian coal mine gas-to-energy project, the largest of its kind in the world in terms of total power output.
Coal mine gas will power the GE Jenbacher JMS 620 GS-S.LC cogeneration systems to generate 131 megawatts of total electrical and thermal output. The contract was awarded by the Lease-Holding Company Coal Mine Named After A.F. Sasyadko, headquartered in Donezk, southeastern Ukraine.
The heat and power will support operations at three Sasyadko sites inside and near Donezk.
The Ukraine mine gas plant is expected to begin commercial operation no later than the fourth quarter of 2004.
The equipment for the German and Ukraine projects was manufactured at GE Jenbacher's facilities in Jenbach, Austria.
Coal mine gas, which is 25 to 60% methane, together with air can form an explosive mixture. Coal mine gas is present both as liberated gas in fissure faults and pores and as absorbed gas on the inner surface of the coal and neighboring rock. Combustion of this gas in gas engines effectively resolves environmental and safety problems while economically utilizing an otherwise lost source of energy.
For nearly 20 years, GE Jenbacher has specialized in the combustion of special gases in its gas engines.
