摘要： A pulverized coal steam generator (10) employing low NOx firing methods is operated at very low excess air levels. This is possible because the unburned carbon in the flyash is measured and the pulverizers (24) are adjusted to control the particles size of the pulverized coal and maintain a desired carbon level.

摘要： A minimum recirculation flame control (MRFC) solid fuel nozzle tip (12) that is particularly suited to being cooperatively associated with a pulverized solid fuel nozzle (34) of a firing system of the type employed in a pulverized solid fuel-fired furnace (10). The MRFC solid fuel nozzle tip (12) when so employed is operative to minimize low and negative, i.e., recirculation, velocity regions of the exit plane of the MRFC solid fuel nozzle tip (12), and to reduce available deposition surface on the MRFC solid fuel nozzle tip (12), and to vary the nozzle tip (12)/solid fuel nozzle (34) thermal conditions to keep the 'hot' solid fuel particulate matter from depositing on available metal platework surface of the MRRC solid fuel nozzle tip (12). The MRFC solid fuel nozzle tip (12) includes fuel air shroud means (46), primary air shroud means (48) located within the fuel air shroud means (46), fuel air shroud support means (50) operative for supporting the primary air shroud means (48) relative to the fuel air shroud means (46), and splitter plate means (52) mounted in supported relation within the primary air shroud means (48).

摘要： A method for enhancing the minimization of NOx control in a circulating fluid bed steam generator (12) into which there is injected fuel, fluidizing air, a lower level of combustion air and an upper level of combustion air. The fuel is injected at a first location (30), the fluidizing air is injected at a second location (24), the lower level of combustion air is injected at a third location (50b) and the upper level of combustion air is injected at a fourth location (50a). In order to enhance the minimization of NOx control within a circulating fluid bed steam generator (12) the lower level combustion air (50b) as well as the upper level combustion air (50a) are each biased in the horizontal plane as well as the vertical plane so as to thereby control the lower level combustion air flow (50b) and the upper level combustion air flow (50a) such that local stoichiometries within the circulating fluid bed steam generator (12) are maintained within a range of 70 % stoichiometry to 90 % stoichiometry.

摘要： A coal fired power plant includes the catalytic reduction of NOx in the flue gas and the catalytic oxidation of SO2 to SO3 followed by the hydration of the SO3 to H2SO4 vapor and then the condensation to H2SO4 liquid. The condensation takes place in a wet sulfuric acid condenser by heat exchange with incoming combustion air. A portion of the heat picked up by that combustion air is used to provide a portion of the heat for the condensate from the steam turbine. The combustion air is then fed to an air preheater and to the steam generator as primary and secondary combustion air.

摘要： 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 fludizing 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. Inerts/tramp materials/clinkers as well as large diameter solids entrained with the material (42b) are segregated therefrom and then are removed (64) from the fluidized bed combustor (12).
