ERK - Water-Cooled Inclined Grate Firing Systems

Our experience with water-cooled inclined grates goes back decades and the technology has proven to be effective for many biomass and coal feedstocks. As the name indicates, the grate is water-cooled and the water circulation is incorporated into the boiler’s water circulation. The grate is a membrane wall construction with air nozzles for primary air supply. The angle of the grate is adapted to the fuel specification. Until now, all installations had a fixed grate angle and we are now commercializing an improved version where we can adjust the grate angle during operation to use a variety of fuels.
