Thermal treatment of waste – an efficient, environmentally sound solution for modern cities

Municipal solid waste is delivered to the site and stored in a bunker. A crane both thoroughly mixes and feeds the waste into the feed hopper. From there it is pushed onto the grate by a ram feeder. A fully integrated control system ensures stable and efficient operation and optimized fire position on the grate. Upon completion of the combustion, the remaining inert ashes fall into the bottom ash extractor, from where they can be taken to a bunker or storage area for metals recovery and for further use.

The gases released from the waste are mixed with secondary air and recirculated flue gases above the grate. This assures complete combustion and lowest CO, NOx and VOC emissions. The recirculation of flue gases also increases the plant’s energy efficiency. The energy released is used to produce superheated steam, which is expanded in a turbine generator to generate electricity. Flue gases are then cleaned to strictest standards and are continuously monitored before they are released at the stack.
