摘要： A method and apparatus for combustion of a fuel in which a first-stage fuel and a first-stage oxidant are introduced into a combustion chamber and ignited, forming a primary combustion zone. At least about 5% of the total heat output produced by combustion of the first-stage fuel and the first-stage oxidant is removed from the primary combustion zone, forming cooled first-stage combustion products. A portion of the cooled first-stage combustion products from a downstream region of the primary combustion zone is recirculated to an upstream region of primary combustion zone. A second-stage fuel is introduced into the combustion chamber downstream of the primary combustion zone and ignited, forming a secondary combustion zone. At least about 5% of the heat from the secondary combustion zone is removed. In accordance with one embodiment, a third-stage oxidant is introduced into the combustion chamber downstream of the secondary combustion zone, forming a tertiary combustion zone.

摘要： A firetube boiler furnace having two combustion sections and an in-line intermediate tubular heat transfer section between the two combustion sections and integral to the pressure vessel. This design provides a staged oxidant combustion apparatus with separate in-line combustion chambers for fuel-rich primary combustion and fuel-lean secondary combustion and sufficient cooling of the combustion products from the primary combustion such that when the secondary combustion oxidant is added in the secondary combustion stage, the NOx formation is less than 5 ppmv at 3% O2.

摘要： A combustion system having at least one wall enclosing a combustion chamber and forming a plurality of burner or burner nozzle openings. Disposed within each of the openings is a premix burner or burner nozzle, each of which has a premixed fuel/oxidant outlet proximate the combustion chamber and a fuel/oxidant inlet distal from the combustion chamber. At least a portion of the premix burners or burner nozzles are sized to produce different fuel/oxidant delivery disturbance response times in response to a pressure disturbance within the combustion system. Differences in fuel/oxidant delivery response times are achieved by using burners or burner nozzles having different internal dimensions, different volume flow rates, and, optionally, by varying the fuel/oxidant ratios of the mixtures flowing through the burners or burner nozzles.
