Abstract: Combustion and/or gasification devices for the thermal utilisation of different solid fuels, and a method for controlling a combustion and/or gasification device for small-size solid fuels with throw-feeding. A combustion and/or gasification device includes at least one combustion or gasification chamber and a grate with at least two grate zones which are arranged in a longitudinal direction of the grate. A glowing fire edge is formed in one of the grate zones, especially in the so-called burnout zone.

Abstract: A method for mechanical stoking in firing installations and a firing installation is provided. Fuel is applied to a grate using a mechanical stoker, the grate being disposed in a firing chamber, wherein the mechanical stoker is oriented opposite a delivery direction of the grate. The fuel is introduced directly below a firing chamber ceiling, viewed in the delivery direction of the grate before the end of the grate such that a burnout zone, which does not have fresh fuel applied thereto, is created on the grate between the mechanical stoker and the end of the grate.

Abstract: A thrower wheel of a mechanical stoker is provided. The thrower wheel includes a plurality of blades, which are disposed on a base plate. A height of the blades increases in a radial direction in at least one area and optionally remains the same in one or more remaining areas, and the height of the blades is less at the inner end of the blades than at the outer end of the blades.
