Mechanical stokers ТЛП (TLP), ТЛПМ (TLPM) Mechanical stokers with chain-belt forward motion grate are intended for burning black and brown coals in steam and water boilers as well as in furnaces.

In the stokers because of the grate motions a persistent spreading from coal box 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.
