Industrial Watertube Boilers - John Thompson
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.
