Mannheim, June 06, 2012<\/p>\n

Germany\u2019s energy policy shift away from nuclear energy in mid 2011 means that the share of renewable resources it uses to generate electric power will increase to 35% by 2020. This can be accomplished through a combination of measures including the increased use of cogeneration<\/a>. The reason: Natural gas-fired plants that produce both heat and electricity and that are used in combination with heat storage equipment may be just the right way to deal with the increasingly wider fluctuations in the level of energy being fed into the power system. Even before Germany\u2019s policy shift in mid 2011, D\u00fcsseldorf International Airport offered a good example of how the demands for combined heat and power (CHP)<\/a> can be optimally met by gas engines and power generators<\/a> from MWM.<\/p>\n

MWM, a Mannheim-based company with a rich tradition of engineering excellence, was the general contractor. It teamed up with the plant\u2019s operator, the municipal utility Stadtwerke D\u00fcsseldorf, to configure the two heat-controlled CHP units. At the heart of the CHP system are two natural gas-fired TCG 2020 V12 engines<\/a>. The heat that is generated is fed into the airport\u2019s heating system as a base load that is used to heat facilities like hangars and aircraft maintenance buildings. The total electrical output is 2 x 999 kW, and the total thermal output is 2 x 1197 kW.<\/p>\n

A unique feature of this twin system, which is individually housed in noise control enclosures, is that the airport\u2019s existing Heating Plant III was expanded to include a powerhouse equipped with heat-controlled medium-voltage modules combined with a stratified heat storage tank, all integrated directly into the active heating system. The electrical power that is generated as a byproduct is fed into the public power grid to help meet peak-load requirements. The multiple-engine systems, which were designed to operate efficiently and take up the least possible space, were installed within a short time frame and put into service for Stadtwerke D\u00fcsseldorf.<\/p>\n

Particularly impressive is the fact that, of a total of 8760 theoretically available operating hours in 2011, the plant was in actual service for about 8550 hours. Not surprisingly, this generated smiles of satisfaction among the operating team. \u201cIn fact, we got 8631 operating hours from one of the gas engines,\u201d reports a happy Michael Heidepeter, manager of Heating Plant III at D\u00fcsseldorf International.<\/p>\n

The product portfolio in MWM\u2019s TCG 2020 series includes a 16-cylinder version and a 20-cylinder version in addition to the 12-cylinder model used in this project. MWM has increased the outputs of this gas engine line to 1200, 1560 and 2000 kW electrical, respectively, which amounts to an effective increase of electrical efficiency of up to 3.3%. In particular this series natural gas- and special gas-powered engines achieves top performance and is setting new standards in direct comparison with other models currently on the market.<\/p>\n

Looking back, Michael Heidepeter thinks the decision to go with MWM was the right one. \u201cSince the project was completed in 2010 and our own district heating system was optimized to operate with the CHP plant, the plant has been working perfectly\u2014day in, day out,\u201d adds Heidepeter.<\/p>\n
