Mechanical ТЧМ stokers with the forward chain motion rippled gate are intended for burning of black and brown coals, riddled anthracite АС and АМ in the steam boilers the productivity of which is up to 25 tons/h as well as waste wood in the multifuel boilers evaporative capacity of which is up to 75 tons/h, and in the furnaces.

In the stokers, because of the grate motions, a persistent spreading to combustion chamber and the process of slag removal are realized. The characteristic feature of the stoker is the upper ignition; the combustion takes place in the thick fuel bed.
