摘要： A dual phase fuel feeder is disclosed that can be used to provide both solid fuels and liquid fuels to a boiler, such as a fluidized bed boiler. The fuel feeder includes a sloped chute which defines a solid feedpath. Gas distribution nozzles are located at the base of the fuel feeder, and secondary nozzles are located so as to be able to distribute a liquid or particulate fuel into the solid feedpath. This permits the liquid fuel to contact the solid fuel and be carried into the fluidized bed instead of becoming suspended above the bed.

摘要： A boiler furnace that is adapted to burn slag producing pulverized coal in suspended form at the upper end of the furnace in which solid fuel is being burned on a subjacent grate. The boiler furnace has an upright combustion chamber with baffles intermediate the upper portion of the furnace and the grate to effectively arrest slag that falls from the upper portion of the furnace before it reaches the subjacent grate.

摘要： A co-firing process is described using cleaned coal and processed biomass to reduce adverse by-products in a coal combusting apparatus. The coal feedstock comprises an aggregate blend of cleaned coal and processed biomass. The biomass feedstock comprises processed biomass pellets. The total energy density is predetermined and can be similar to the coal component or higher than the coal component. The intracellular salt in the processed biomass is at least 60 wt % less for the processed organic-carbon-containing feedstock used to make the processed biomass pellets than that of the starting un-processed processed organic-carbon-containing feedstock. The cleaned coal has a sulfur content that is 50 wt % less than that of un-cleaned coal before it passed through the coal-cleaning sub-system.

摘要： A method of injection and combustion control and related injection nozzles and lances are described which facilitate the merging of the combustion of fossil fuels and separately added solid biomass waste product fuels in the form of pelletized chars and fine particulates. An assembly of five concentric, annular tubes and conically shaped exit tips is used to deliver air conveyed biomass fuel as an annular stream between two higher velocity air streams, both of which converge so as to accelerate and propel the biomass fuel, and distribute it into the flame zone produced in a conventional fossil fueled boiler. The additional air required for combustion of the biomass fuel is fed to the expanding plume produced by the fuel delivery stream and adjoining air streams. A portion of the combustion air is delivered through the inside of the inner tube in sufficient volume to provide the entrainment flow produced by the expanding air streams.

摘要： A method of injection and combustion control and related injection nozzles and lances are described which facilitate the merging of the combustion of fossil fuels and separately added solid biomass waste product fuels in the form of pelletized chars and fine particulates. The teachings of this inventor's earlier patent, “Variable Gas Atomization,” U.S. Pat. No. 4,314,670, (referred to herein as VGA) are employed. They are applied in a distinctly different manner so as to enable air conveyed and injected solids to be accelerated, propelled and distributed in the combustion zone of fossil or biomass fuel boilers. While the use of an annular nozzle configuration with conically flared exit tips is generally similar, the functions to be performed, and the related conical exit configuration, differ. An assembly of five concentric, annular tubes and conically shaped exit tips is used to deliver air conveyed biomass fuel as an annular stream between two higher velocity air streams, both of which converge so as to accelerate and propel the biomass fuel, and distribute it into the flame zone produced in a conventional fossil fueled boiler. The additional air required for combustion of the biomass fuel is fed to the expanding plume produced by the fuel delivery stream and adjoining air streams. A portion of the combustion air is delivered through the inside of the inner tube in sufficient volume to provide the entrainment flow produced by the expanding air streams. In so doing, it prevents undesirable recirculation of combustion gases and unburned fuel. The remainder of the combustion air is delivered through an additional annular nozzle located on the opposite side of the expanding streams to similarly mix with the fuel.

摘要： The present invention is a process and associated apparatus for obtaining energy from a fuel source having particles varying in size from fines to coarse. The fuel source is introduced into a passageway formed between an upper combustor and a lower combustor. A gas stream is moved upwardly through the passageway such that the fine particles are entrained in the gaseous stream and carried into the upper combustor.

摘要： A low BTU, low volatile content, low carbon and high ash fuel is combusted in a combined shaft kiln combustor and fluidized bed combustor to generate heat which is converted to useful energy. The fluidized bed combustor is mounted vertically above the shaft kiln combustor. A venturi is provided in a passageway connecting the shaft kiln combustor and the fluidized bed combustor to produce a gaseous stream moving at a velocity sufficient to separate finer particles from the low BTU, low volatile content, low carbon and high ash fuel so that the coarser particles are burned in the shaft kiln combustor and the finer particles are burned in the fluidized bed combustor.
