Overfeed stoker 3. Underfeed stoker. Within each category, stokers differ in how the grate handles ash. A typical spreader-stoker boiler consists of a variable-feeding device, a mechanism for "throwing" coal into the boiler, and one or more grates, depending on capacity, with suitable openings for admitting combustion air.
