    摘要: A method for combusting a fuel in a cyclone combustor having a burner and a barrel includes: feeding a stream of the fuel into the barrel at the burner end of the barrel; feeding a stream(s) of a first oxidant (e.g., air) having a first oxygen concentration into the barrel at a first flowrate, the stream(s) of the first oxidant including a predominant stream; feeding a stream(s) of a second oxidant (e.g., oxygen) having a second oxygen concentration into the barrel at a second flowrate and in a selective manner, whereby a portion of the first oxidant combines with a portion of the second oxidant, thereby forming a combined oxidant having a combined oxygen concentration, and a portion of the first oxidant from the predominant stream continues having the first oxygen concentration; and combusting a portion of the fuel with a portion of the combined oxidant in the barrel.

    摘要: A burner includes separate fuel and oxidant conduits. The fuel conduit has inlet, transitional, and outlet sections, and the oxidant conduit has inlet and outlet sections. The cross sectional flow area of the fuel transitional section varies from an initial cross sectional flow area at the fuel intake to a different cross sectional flow area at the fuel outtake, and the cross sectional flow area of the fuel outlet section is substantially uniform. At least some of the oxidant inlet section is spaced around substantially all of at least a portion of at least one of the fuel inlet, transitional, and outlet sections. The cross sectional flow area of the oxidant outlet section is less than or equal to the cross sectional flow area of the oxidant inlet section and is substantially uniform, and at least some of it is spaced around substantially all of at least a portion of the fuel outlet section.
