Operational experience with an innovative 190 kW CHP unit with gas engine and exhaust gas recirculation

摘要

In February 2003 a CHP unit of the type TBG 926 EGR started operation at RWE Rhein-Ruhr AG in Duisburg.This installation represents one of the first of this type in Germany.Until December 2005 the unit reached more than 14 500 hours of successful operating and testing.The unit was build by a company called Menag Energie AG from Switzerland.The electrical and thermal output is supposed to be 190 and 256 kW at a hot water temperature of 85 deg C.During the test run it was possible to confirm the performance data and specially the low emissions proposed by the manufacturer.The following article will describe the innovative design using the exhaust gas recirculation.Furthermore it shows the results of the test run and gives estimation about the usability of this innovative CHP system.
