    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 watercooled, 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.

    Fuel is burned in today's stokers on mechanical traveling, reciproing or water/air cooled vibrating grates. Fuel is introduced on the grate through multiple fuel delivery chutes on one side of the boiler using a mechanical or pneumatic system. The pneumatic fuel distributor design allows for side and depth distribution adjustments. This is achieved by controlling the air pressure, air ...
