Boiler Classification and Application - CED Engineering

Stoker-fired boilers include a mechanical system that is designed to feed solid fuel into the boiler. These stokers are designed to support the combustion process and to remove the ash as it accumulates. All stokers operate similarly. They use both undergrate and overfire air to burn fuel located on a grate.

Spreaders stokers are more expensive than other stokers in small sizes, and are more expensive than pulverized coal boilers in large sizes (over 500,000 Ibm/hr of steam) but are very common in the intermediate (large industrial) size range. Compared to previous stokers, more fuel burning occurs in suspension- that is, in the air as the fine

Keystoker Problems Please Help! | Stoker Coal Furnaces

Grate-fired boilers or stokers are the oldest method used for direct combustion of solid fuels. The main advantage of grate-fired boilers compared to their main rival, fluidised-bed boilers, is their ability to burn various fuels with little pre-handling. Grate-fired units are not sensitive to large metal, glass, stone impurities etc., and they do not suffer from bed agglomeration problems as …
