LAWI - Model EtaComb -Moving Grates for Solid Waste Combustion

The moving step grate design with multiple independent zones and a sophisticated zone-independent air distribution system allows a sufficient mixture of the fuel with air in each zone. The operation mode of the moving grates can be adjusted in relation of burning behavior as well as fuel size and bulk density.

Apart from the grate bars, the grate consists of grate carriages, support rollers, guiding tracks, guiding rollers, separation walls with moving grate base frame and casing as well as temperature and position instrumentation.  Grate movement is controlled by timer and piston position control via proximity switches.
