Abstract: A modular-hinged grilling grate system may include a modular outer support structure and at least one attachable swivel grill grate section.

Abstract: A cooking apparatus with a cooking container in which is received a fuel component support device. The cooking apparatus having an adjustment mechanism drivingly connected with the fuel component support device. The adjustment mechanism includes a handle section and an interconnected shaft assembly connected with the handle section, the interconnected shaft assembly including a first shaft section and a linkage assembly drivingly connected to the first shaft section and positioned between a base portion of the cooking container and the fuel component support device such that rotation of the first shaft, as by a vertical swinging of the handle section, produces an opposite direction change in vertical height in the linkage assembly and the supported fuel component support device. A handle engagement section is provided as in one that includes a plurality of height position stop engagement locations.

Abstract: The invention relates to a hydraulic drive for a water-cooled sliding combustion grate. Each displaceable grate stage (6) is connected to at least one connection rod (30) supported at the other end thereof on a crank (31), wherein the associated crankshaft (32) is supported in a bushing (33) penetrating the side wall (2) of the grate construction. A crank (34) connected to the piston (35) of a hydraulic cylinder-piston unit (36, 35) is seated on the other side of the crankshaft (32), outside of the actual grate construction of the associated grate run, where said hydraulic cylinder-piston unit is disposed. The hydraulic components are thereby spaced further away from grate plates, and not exposed to abrasion. Said components, being disposed remotely from the grate plates (6), can also be replaced during operation of the grate.

Abstract: A grate furnace with a grate includes grate steps made of grate elements lying next to one another. Every second grate step in the longitudinal direction of the grate can be driven for carrying out stoking movements and the grate steps in each case lying therebetween are stationary. Drive devices for driving the moveable grates are arranged in housing chambers and are in this way protected against impairment caused by material falling through the grate. A certain section of the housing chamber is open toward the bottom so that it is accessible even during operation of the grate furnace.

Abstract: 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. The air plenum unit is coupled to an air supply for providing combustion air through the top grate surface air-flow apertures. The air plenum unit includes multiple zones, each of which zones has an associated air flow control damper so that the flow of combustion air can be controlled. Ash siftings formed on the grate top surface when the biomass or other fuel is combusted fall into the air plenum unit and flow toward at least one ash-siftings discharge opening at a discharge end of the air plenum when the grate top surface and the air plenum is vibrated.

Abstract: A furnace grate for use in a combustion furnace includes rows of grate bars positioned one behind the other, moveable and stationary grate bar supports, side plates, drive shafts and fluid cylinders. The grate bars are seated on the grate bar supports within the furnace while the fluid cylinders are positioned outside the furnace wall.

Abstract: A wood burning stove incorporates a catalytic cell for reducing exhaust emissions from the stove. A pair of heat shields are spaced from opposing surfaces of a combustor to exchange thermal radiation with the combustor. The combustor is oriented at an acute angle to enhance the combustor life. One of the heat shields also functions as a deflector for deflecting exhaust toward the combustor. A secondary air unit supplies secondary air to the vicinity of the combustor. A dynamic grate assembly is employed to prevent under firing of the firebox.

Abstract: A coal burning grate for furnaces which is reciprocatably mounted to feed coal from a hopper into the furnace and to simultaneously remove ash from the furnace to an external ashpit. The grate may include a heel attached to the grate shoe to move ash in the ash pit to assist in the removal of the ash from the furnace.
