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 cement kiln burner device includes a powdered-solid-fuel flow channel, a first air flow channel placed inside the powdered-solid-fuel flow channel to be adjacent to the powdered-solid-fuel flow channel, having means for swirling an air flow, an outer air flow-channel group placed concentrically in an outermost side outside the powdered-solid-fuel flow channel, having three or more second air flow channels adapted to form means for straightly forwarding an air flow, and a combustible-solid-waste flow channel placed inside the first air flow channel. The second air flow channels are placed proximally to each other in a radial direction within a range where air flows ejected from the respective second air flow channels are merged to form a single air flow, and are configured to control flow rates of the air flow ejected from the respective second air flow channels, independently for each second air flow channel.

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 hybrid combustion system is provided combining advantages of a fluidized bed combustion portion and a pulverized coal combustion portion. The former portion includes a fluidized bed chamber, a coal mill without an air separator, a recycling duct connected to the coal mill, a coal supply duct, and a spray feeder. The fluidized coal combustion portion includes a pulverizing coal mill with air separator, a blowing duct for blowing ground coal, at least one pulverized coal burner and an air recycling duct for recycling combustion air. Fluidized bed combustion takes place in a lower part of the system and pulverized coal combustion takes place above the fluidized bed combustion. Each of the portions may be independently operated of the other. A main combustion chamber is common to both the fluidized bed portion and the pulverized coal portion. A related process is also described.

摘要： A furnace control system to control burner operation of a multifuel furnace to reduce primary fuel consumption of either oil or gas of the multifuel furnace. The system controls a primary fuel to initially kindle a secondary fuel when the fire reaches a self-sustaining burning rate, the primary fuel is shut off but the burner fan continues to run to force a draft and insure complete combustion of the secondary fuel and the volatile gases. The furnace control system is utilized as original equipment manufacturer incorporated into the controls for a burner of a multifuel furnace or as a retrofit furnace control system to control the burner operation of the multifuel furnace.
