Gas Engine Project and Field Experiences from MAN Diesel Turbo SE A power plant in the smallest possible space

摘要

MAN Diesel & Turbo SE was asked by VW Kraftwerk GmbH to build a combined heat and power (CHP) plant on the Volkswagen site in Brunswick. The modern and highly efficient 20V35/44G gas engine was installed, with an output capacity of 10.4 MWe and 9.15 MWth. In this special configuration the plant achieves a net overall efficiency of 84.3%. The request included engineering and planning services, together with genset delivery and various mechanical and electrical components. Furthermore, the client required the plant to be assembled and made ready for use. The project was a huge challenge. Besides having to respect strict noise and emission limits in line with the TA-Luft regulation and meeting common European standards, there were also special re-quirements in terms of the construction. As a result of its location within the Volkswagen production site, the plant had to be constructed in a very confined space. One part of the plant was installed in an existing building, while another part was housed in a new building, which was to be constructed by the client. The main components for the extraction of heat from waste gas were installed in the existing boiler house, within its sub-basement that had a height of 2.3 metres, while the motor itself, together with the systems for the extraction of heat from the engine coolant water and for the waste gas treatment, were housed in a new three-storey building next door.
