The John Thompson vibrating grate was developed for the combustion of biomass and other low ash solid fuels with up to 50% moisture content. Either air- or water-cooled, the grate surface is intermittently vibrated with the use of an eccentric drive and a leaf spring mounting arrangement to induce continuous movement of the fuel bed towards the ash discharge end.Learn More
Grate-firing of biomass for heat and power production - ScienceDirectLearn More
allows the boiler to handle various types of fuels and somewhat variable moisture contents. Stoker fired boilers fire a wide range of biomass fuels including agricultural wastes, wood waste and municipal solid waste derived fuels. Biomass combustion technology has evolved from incineration of a nuisance waste fuel to combustion of a valuable fuel.Learn More
Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressureLearn More

Another boiler type sometimes used for wood combustion is the suspension-fired boiler. This boiler differs from a spreader stoker in that small-sized fuel (normally less than 2 mm) is blown into the boiler and combusted by supporting it in air rather than on fixed grates. Rapid changes in combustionLearn More
