  • US6220190B1 - Water-cooled oscillating grate system

    An integral water-cooled, air permeated, vibrating grate system for combusting biomass and other fuels in a boiler includes a grate top surface having air-flow apertures extending therethrough. The grate top surface is supported by a plurality of water-cooling pipes which arc coupled to a water supply. An enclosed air plenum unit is positioned under and attached directly to the grate top surface.Learn More
