2015-9-10 · boiler differs from a spreader stoker in that small-sized fuel (normally less than 2 mm and normally low moisture) is blown into the boiler and combusted by supporting it in air rather than on fixed grates. Rapid changes in combustion rate and, therefore, steam generation rate are possible because the finely divided fuel particles burn very

These Boilers have intrinsic features for the operation of trouble-free and high-thermal efficiency. These are classified based on the technique of supply fuel to the boiler amp; with the grate type. The stoker-fired boilers are classified into two types namely chain-gate or traveling grate stoker and spreader stoker. Advantages of Steam Boiler

stoker boiler Steam Boiler Factory Price. They are common on steam locomotives after 1900 and are also used on ships and power stations. Known now as a spreader stoker they remain in use today especially in furnaces fueled by wood pellets or refuse.1 Automatic Coal- Fired Boiler Providing heat when you These furnaces use coal to provide you warmth and efficiency.

Spreader Stoker Boiler. Spreader stokers (see figure 2.6) utilize a combination of suspension burning and grate burning. The coal is continually fed into the furnace above a burning bed of coal. The coal fines are burned in suspension; the larger particles fall to the . Learn More

A spreader stoker continuously feeds fuel, either coal or wood, into the boiler above the combustion bed. Some of the fuel burns in suspension with the larger pieces falling and burning on the grates. The feeding into the firebox can either be ent

AET Combustion System The most important decision in the design of a well-functioning biomass-fired plant is the choice of combustion system. The AET Combustion System is based upon the AET Spreader Stoker and AET BioGrate. The fuel challenge. Some biomass fuels have ash content with a strong tendency to slag and block the heat transfer surfaces.
