Fluidised bed furnace and pyrolysis reactor
Fluidised bed furnace and pyrolysis reactor are main components of the biomass combined heating and power plant constructed on the industrial site of Bauer Holzenergie GmbH in Bad Rappenau, in order to generate electrical energy and district heating from wood.
Total burner capacity: approx. 14 MW
Electrical output: 2 MW
The pyrolysis reactor (diameter 3.2, height 8 m, weight 8 t) was designed for a maximum permissible operating overpressure of 1 bar and a max. perm. operating temperature of 390 °C.
The water-cooled 5 MW fluidised bed furnace (Lx W x H: 11.5 x 4.2 x 4.2 m, weight 35 t) was designed for a perm. operating overpressure of 0.5 bar and a perm. operating temp. of 390 °C.
A direct-fired clean steam system from stainless steel was delivered for a foodstuff disinfection plant from our long-term strategic partner, SteamLab GmbH of Hamburg. This system was put to use by Bejo Zaden B.V., Holland, one of the world’s leaders in the field of seed development and production.
The system comprises a rapid steam generator 500 kg/h as three-pass instantaneous water heater, a high pressure steam vessel with 500 litre capacity, a feed water tank, a water treatment system and a sludge cooler. The complete system was prefabricated in the factory and preassembled on a stainless steel base frame as a packaged unit.
