A consortium comprising ThyssenKrupp Xervon Energy GmbH, Duisburg, and Baumgarte Boiler Systems GmbH, Bielefeld, has been awarded by Bremen public services swb Erzeugung, Bremen, the contract to build a new energy recovery plant engineered to incinerate alternative medium-calorie combustibles (medium CVs) and able to supply around 60,000 homes with electricity. The contract is worth a total €37 million and the plant scheduled to come on stream at the start of 2009.
Medium-calorie combustibles may be sourced from both normal waste residuals but also directly in the course of industrial processes. Their mean CV is 14 MJ/kg, the bandwidth ranging from 11 to 18 MJ/kg. Under full-load conditions, the new plant will feed around 29 MW (electric) into the swb Erzeugung grid, equivalent to electricity for about 60,000 households.
With a steam output of 127 t/h and at 40 bar main steam pressure and 400 °C main steam temperature, this is the biggest ever incineration boiler engineered by Baumgarte Boiler Systems GmbH. ThyssenKrupp Xervon Energy will supply the water-cooled moving grate and its accessory equipment.
ThyssenKrupp Xervon Energy GmbH, a subsidiary of ThyssenKrupp Services AG, is a leading international supplier of services for all aspects of energy and power generation plant. Alongside its own incineration plants and burner systems, its capabilities comprise repair, modernization, conversion, and optimization work on steam generators of all types and sizes used in conventional power plants. Completing the lineup are the maintenance and modernization of flue gas purification plants and heat exchangers in conventional power plants.
