In stoker boilers, the fuel is combusted in relatively thin layers on top of a "grate." Stoker boilers are typically characterized according to the way fuel is transported to the grate . There are several ways to accomplish this. The most common type is the spreader stoker, where the fuel is "spread" above the grate, allowing the

The fuel is burned in stoker (6), falling on special slotted grates. Further, passing through the combustion chamber and a three-way heat exchanger, the initial hot gases give up their coolant energy, and the gases themselves with the help of the exhaust fan (12), having been cleaned in a multi-cyclone filter, are discharged into the atmosphere through the chimney (13).
