SRS EcoTherm GmbH operates an industrial power plant (IKW) in the Salzbergen industrial park, consisting of a waste incineration plant, an oil-fired boiler 7 and a gas-fired boiler 8, in order to guarantee the site’s electricity and steam requirements.

Taking into account an increasing tightening of the 13^th BImSchV, various options for action (including furnace/flue gas cleaning conversion) for a continued operation of boiler 7 were investigated and evaluated both technically and economically. In particular, it was to be examined which measures or investments would be necessary to expand the usable fuel range of boiler 7 with regard to the parameters sulfur and nitrogen in order to increase the operational flexibility of the IKW.
