This type of grate is suitable for the entire range of fuels. Because of the closed feed motion of the entire grate bar series, it is insensitive to undesired substances which reach the grate through the fuel feed. The stroke speed can be set independently for each drive cylinder, and the undergrate air can be controlled in sections.

The air-cooled reciprocating grate is structured like a staircase from fixed and moving grate bar series. In the reciprocating grate, every 2nd grate bar series is moved when the combustible is fed as against the overthrust grate. The burnt fuel via the slag hoppers at the lower end of the grate

The drive of the moved grate bar series takes place hydraulically via a central unit wherein the number of strokes and length of strokes can be adjusted variably per drive.

The combustion air, which at the same time serves in the cooling of the grate layer, is fed via individually controllable undergrate wind zones of firing. It seeps in to the combustible bed through air slots in the grate bars.  

Since 1985, reciprocating grates are a part of the scope of delivery of Richard Kablitz GmbH.
