Abstract: An improved fire grate may provide fresh oxygen rich air to a secondary combustion zone, created by the improved fire grate, of a combustion chamber where a combustion gas stream is typically oxygen starved assisting in the burning process of incompletely burned particulates and reducing other harmful emissions. A baffle plate may be introduced in the secondary combustion zone to increase a combustion chamber temperature, encourage mixing of oxygen starved air with oxygen rich air and increase a residence time of the combustion gas within the combustion chamber. These aspects of the baffle plate promote more efficient burning of the biomass/fuel. Additionally, log lighter(s) may be disposed in the secondary combustion zone to increase a temperature of the combustion chamber for the purposes of reducing harmful emissions. The improved fire grate may be horizontally and vertically adjusted to fit within different sized fireplace combustion chambers.

Abstract: A grate block for an incinerator has a top wall and a front wall that extends from the front wall. A pair of side walls wherein each sidewall extends from the top wall and the front wall. Each of the side walls of the grate blocks engage the side wall of the adjacent grate block. Each side wall has a recess in proximity to the front wall/upper wall interface. The recess defines a gap between the side walls of the adjacent grate blocks. An opening in the recess through the side wall allows for the flow of air from a cavity within the grate block. The slot created by the recess of the two adjoining grate blocks has a narrower slot opening created by a shallow upper recess and a broader slot opening created by a deeper lower recess. In that the openings are not directly aligned with any of the exposed surfaces, the air is required to make a perpendicular turn prior to exiting the recess of the grate block.

Abstract: A combustion enhancing member employed with a stoker combustion system is disposed on the grate of the stoker and includes at least one chamber. The chamber has at least one fluid inlet for receiving a combustion enhancing fluid and a plurality of fluid outlets for distributing the fluid to the bed of fuel moving along the grate of a stoker combustion system, thereby increasing the burning efficiency of the stoker.

Abstract: A process wherein primary air supplied to the combustion bed through the thrust combustion grate is deflected after exiting from a surface of the thrust combustion grate by deflector elements mounted on the surface of the thrust combustion grate. The grate required for this purpose has grate plates made from a permeable hollow element with connection pieces for supplying and draining cooling water, with primary air supply ducts that run through the grate plate from a bottom to a top. Deflector elements against which the primary air exiting the outlet is intended to impact, are disposed over openings of the primary air supply ducts.

Abstract: A roller grate arrangement for garbage-incinerating plants, in which a plurality of rollers with horizontal and parallel axes lie in an inclined plane. Primary air is fed to interiors of the rollers by air boxes located below the grate. The rollers have surfaces with air gaps for supplying the primary air, and the rollers are positioned to form a space between adjacent rollers. A component in the space between adjacent rollers, bridges the space between adjacent rollers. The component is free of air passages. Blast pipes are positioned in spaces between adjacent rollers and are connected to a separate system for feeding supplemental air.

Abstract: A solid fuel internal combustion engine is disclosed having a tank for storing particulated solid fuel such as, for example, wood. A combustion chamber is positioned proximate to the storage tank for receiving the solid fuel stored therein, wherein the solid fuel is preheated by the exhaust gases from the combustion chamber but is not ignited until the wood enters the combustion chamber. A portion of the exhaust gases from the combustion chamber is coupled to a compression turbine which in turn drives an air compressor for forcing air or other oxidizing agent under pressure into the combustion chamber. The cold compressed air serves as a combusting agent for igniting and burning the particulated wood. A major portion of the exhaust gases from the combustion chamber is controllably coupled to a power turbine for driving a vehicle or other utilization device.
