With pneumatic spreader and clinker grates; are intended for burning of black and brown coals and anthracites under steam and hot-water boilers and in the furnaces.

The stokers work on the principle of a continuous spreading to the active bed.

Due to the intensive lower ignition of the fresh fuel throughout the whole grate area, the stoker can work on hard-ignitable fuels as well as on the brown coals of high humidity.

The characteristic feature of those stokers is a combination of mechanical, as the basic, and pneumatic spreading, which makes it possible to optimize combustion of dust fractions in the furnace volume. The stoker construction automates combustion action.
