New gas-fired cogeneration plant with Tognum technology in mtu Plant 1
Posted on May 15, 2007
Friedrichshafen - The Tognum subsidiary MTU Friedrichshafen is applying economical and environmentally friendly power generation for its own needs with a new natural-gas-fired cogeneration plant producing electricity and heat in its Plant 1. The plant was produced by Tognum subsidiary MDE and supplies 1.8 megawatts of electrical power and 2 megawatts of heating power.
"The technology for gas-energy systems is one of Tognum's key future markets. We see a worldwide boom for cogeneration and decentralized power generation with bio-gas and natural gas," states Christof von Branconi, Head of the Tognum division Energy Systems and Components. "With plants for the decentralized power generation on a diesel, gas and fuel-cell basis, Tognum is well positioned in both traditional and future-oriented energy markets."
Decentralized cogeneration uses energy particularly efficiently: When electricity is generated, heat is produced which can be directly applied. In mtu's Plant 1, 8,800 megawatt hours of heat will be used to heat the building as well as for heating engine test benches. In this way, up to 87% of the energy in the natural gas is used. This rate of efficiency is 40% higher than the conventional large-scale power plants used to generate electricity in the German power grid. Compared with the separate generation of electricity and heat, cogeneration plants reduce CO2 emissions by 1,700 tons each year.
"But cogeneration plants make sense not only from an ecological, but also from an economical viewpoint," explains MDE CEO Dirk Naujokat. "The primary energy saved pays off for mtu in cash. Another point is that the cogeneration plant makes mtu less dependent on the public network and thus serves to improve security of supply." The system technology for the gas-fired cogeneration plant in mtu Plant 1 comes from the Tognum group of companies: With mtu's facility management as the customer, the Tognum subsidiary MDE Dezentrale Energiesysteme in Augsburg installed the cogeneration plant in the newly extended heating room. The core element of the cogeneration plant is a power-boosted gas engine of the mtu 4000 Series. The generator, base frame, control system, heat exchanger, silencer, exhaust aftertreatment, oil supply and room-temperature regulation are the other key components of the total system.
The technology of the new gas-fired cogeneration plant can be seen through a five-square-meter window in the heating building, making it visible how mtu generates environmentally friendly energy itself using technology from within the Tognum Group. The design of the power plant also focused on minimizing noise pollution. After all, technology should be seen, but not heard.
