  • Patent number: 6615750
    Abstract: A sorbent conditioning and direct feed apparatus is provided for direct feeding of a conditioned solid sorbent to a combustor 12. The sorbent conditioning and direct feed apparatus includes raw solid sorbent storages means 102, particle size reducing means 112 for reducing the particle size of solid sorbent supplied thereto from a relatively larger coarse particle size to a relatively smaller fine particle size, metering means 108 for metering the supply of raw solid sorbent from the raw solid sorbent storage means to the particle size reducing means 112, and transport means 118 for transporting solid sorbent which has been conditioned by the particle size reducing means 112 to the combustor 12, whereby conditioned solid sorbent is fed to the combustor 12 without any intermediate storage of the solid sorbent between the raw solid sorbent storage means 102 and the transport means 118.

  • Patent number: 6554061
    Abstract: A recuperative and conductive heat transfer system (10, 10′) that is operative to effect therewith the heating within the second portion (20, 20′) of the heat transfer system (10, 10′) of a “working fluid” flowing through the heat s transfer surfaces (32, 32′) as a consequence of the transfer thereto by conduction of heat from a multiplicity of regenerative solids (24, 24′). The multiplicity of regenerative solids (24, 24′) derive their heat from a recuperation thereby within the first portion (12, 12′) of the heat transfer system (10, 10′) from either an internally generated or an externally generated source of heat (22, 22′).

  • Patent number: 5976224
    Abstract: A method of separating unburned Carbon, as particulate matter, from the flyash produced as a result of the combustion process occurring in a pulverized-coal fired steam generating power plant is disclosed. More particularly the invention separates the flyash into a coarse product group and a fine product group by utilizing the differences in specific gravity between the Carbon particles and remaining flyash as well as utilization of the dynamic classification characteristics of a rotary classifier to effect the separation whereby at least one of the two product groups comprises a relatively low weight percentage of unburned Carbon while yet comprising a relatively high percentage of the total mass of product recovered after separation.

  • Patent number: 5401130
    Abstract: A fluidized bed combustion system (10) particularly suited for use to effect the incineration, i.e., combustion, therewith of wood waste/sludge mixtures that have high moisture and ash content which makes them difficult to burn. The fluidized bed combustion system (10) includes a fluidized bed combustor (12) embodying a fluidized bed (24) composed of bed solids. Air is injected into the fluidized bed (24) through an air distributor (28) to establish a first controlled fluidizing velocity zone and a second controlled fluidizing velocity zone therewithin. Material (42b) is introduced into the fluidized bed combustor (12) above the second controlled fluidizing velocity zone. Bed solids are projected from the first controlled fluidizing velocity zone to the second controlled fluidizing velocity zone whereupon the bed solids rain down upon the material (42b) and effect a covering thereof. The material (42b) is then dried and thereafter combusted.

  • Patent number: 4690076
    Abstract: A method of feeding particulate material (17) to a fluidized bed furnace (10) is provided wherein particulate coal, particulate limestone and particulate material withdrawn from the furnace system are fed to the furnace as a mixture in a unified feed system. Raw coal and limestone are independently crushed to the desired size and premixed to yield a desired calcium to sulfur mole ratio. The premized coal and limestone (7) are passed to a dryer/mixer and contacted therein with hot particulate material (9,19) withdrawn from the fluidized bed furnace system for a period of time sufficient to substantially dry the wet coal and hydrate at least a portion of the lime contained in the hot particulate material. The so-conditioned mixture (15) is then entrained in a conveying gas and fed to the fluidized bed (12) in a conventional manner.

  • Patent number: 4387667
    Abstract: A fluidized bed furnace (10) for generating steam (26) is designed to operate over a given load range, for example from 50% of full load to maximum capacity rating (MCR). The air distributor (12) is designed with a constant pressure drop restriction means or "float" (36) in each air inlet (18). As the load varies, the pressure drop across the float (36) will remain constant, reducing the overall fan horse power requirements.
