摘要: Combustion of petroleum coke using air to carry the fuel into a combustion zone and to provide a source of oxidant. Enhanced combution utilizes oxygen introduced into or proximate primary, secondary, tertiary, quaternary, or over-fire air to effect primary combustion of the fuel. Petroleum coke fuel in an oxygen supported air-petroleum coke combustion process can be used to re-power a utility boiler.

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 method for operating a cyclone combustor having first and second burners in communication with a barrel includes: feeding a stream of a primary fuel and a primary oxidant having a first oxygen concentration into the first burner; feeding a stream of a secondary fuel and a secondary oxidant having a second oxygen concentration greater than or equal to the first oxygen concentration into the second burner; combusting at least a portion of the primary fuel with at least a portion of the primary oxidant in the barrel of the cyclone combustor, thereby forming a plurality of primary products of combustion in the barrel; and combusting at least a portion of the secondary fuel with at least a portion of the secondary oxidant, thereby forming a plurality of secondary products of combustion and a secondary flame, the secondary flame generating a supplemental radiant heat 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.
