2018-12-26 · produced hundreds of spreader stokers for a variety of solid fuel applications for over fifty years. Both the Travagrate0 front ash discharge traveling spreader stoker and the Water cooled stationary grate spreader stoker have been utilized to produce steaming rates from 25,000 pounds of steam per hour up to 500,000 pounds of steam per hour.

2017-9-8 · 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 grate, where they are burned in a thin, fast-burning coal bed.

2019-5-6 · A mechanical stoker is a mechanical system that feeds solid fuel like coal, coke or anthracite into the furnace of a steam boiler. 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
