The Task

For a reliable and sustainable supply of energy to the city of Gießen, the municipal utilities Stadtwerke Gießen AG (SWG) are constructing a thermal residual waste treatment and energy recovery plant. The power plant, designed according to the cogeneration principle, is intended to supply the electricity generated to SWG’s existing electricity network, in order to feed in the electrical energy produced. In addition, the plant will supply energy for the existing district heat network. Standardkessel Baumgarte secured the order for the supply of the steam generator and the grate.

 

The Solution

The feature of the new plant is the combination of waste incineration in conjunction with two gas-driven CHP units which leads to high energy efficiency. The CHP waste gases in this case take on external superheating of the saturated steam generated in the boiler. The firing system, designed as a water-cooled moving grate, is connected to the steam generator consisting of the furnace with the downstream radiation pass and economisers, as well as, the dry flue gas cleaning system and the exhaust heat exchanger, with a planned flue gas temperature of 55 °C.
