摘要： A reactor system and control method. The method includes feeding solid fuel and oxygen containing gas to a first fluidized bed reactor to form a fluidized bed of particles and combusting a first portion of the fuel in the bed with the oxygen containing gas to generate hot bed particles and a first stream of hot flue gas, conveying the first stream to the flue gas channel, transferring hot bed particles including a second portion of the solid fuel at a predetermined hot particles transfer rate from the first reactor to a second fluidized bed reactor, feeding fluidizing gas to the second reactor to form a second fluidized bed, and transferring bed particles from the second reactor to the first. The method includes first and second operation modes. In the first, the fluidizing gas is oxygen containing gas and, in the second, the gas includes steam, CO2, or inert gas.

摘要： A boiler system for producing steam from water includes a plurality of serially arranged oxy fuel boilers. Each boiler has an inlet in flow communication with a plurality of tubes. The tubes of each boiler form at least one water wall. Each of the boilers is configured to substantially prevent the introduction of air. Each boiler includes an oxy fuel combustion system including an oxygen supply for supplying oxygen having a purity of greater than 21 percent, a carbon based fuel supply for supplying a carbon based fuel and at least one oxy-fuel burner system for feeding the oxygen and the carbon based fuel into its respective boiler in a near stoichiometric proportion. The oxy fuel system is configured to limit an excess of either the oxygen or the carbon based fuel to a predetermined tolerance. The boiler tubes of each boiler are configured for direct, radiant energy exposure for energy transfer. Each of the boilers is independent of each of the other boilers.

摘要： A pellet stove utilizing gravity feed and natural draft more effectively and efficiently burns pellet fuel while producing less air pollution and ash. In one embodiment, the pellet stove has a primary combustion area comprising a burn unit removably disposed in the vent tube, a feed tube defining a fuel chamber above the burn unit and a secondary combustion area, comprising a burn box defining a secondary burn chamber, below the burn unit. The burn unit has a removable receptacle which defines a primary burn chamber that receives pellet fuel from the fuel chamber and discharges substantially burned fuel to the secondary burn chamber for additional burning. Openings in the burn box, pellet receptacle and vent tube draw air into the burn chambers. A control mechanism controls the air flow to regulate the heat generated by the pellet stove. The pellet stove can be manufactured in various aesthetically pleasing designs.

摘要： A device for gasifying biomass waste has two each of primary chambers, fume transfer vents, mixing chambers which accept fumes from the primary chamber, afterburner chambers in fluid communication with the mixing chambers, and an exhaust duct. Each secondary burner produces an initial heating flame within a vertical portion of the respective afterburner chamber, and secondary chambers are in fluid communication with the afterburner chambers. Heated gases from the afterburner chambers cause heating of the secondary chambers. A portion of each primary chamber has a heat conductive floor superimposed over the respective secondary chamber, and the partition between the primary chambers is heat conductive, so that conductive and convective heating of the primary chambers occurs.

摘要： A combustion system for extracting thermal energy from biomass or other formable fuels that does not require densification or other processing of the biomass prior to combustion. This system continuously feeds the biomass fuel from an auger or other conveyance system while simultaneously causing the biomass fuel to be formed with a hollow core. The biomass fuel is ignited from within the hollow core and burns primarily radially outward due to negative pressure surrounding combustion chamber thus facilitating and containing the combustion process. This system also utilizes pre-heating the fuel, primary and secondary air pre-heating, insulated combustion chambers, and carefully control combustion air to ensure substantial combustion is achieved even with fuels having high moisture content. In the preferred embodiment, a heat exchanger is utilized to capture thermal energy of combustion products for use as an energy source for additional processes.
