Definitions
- a secondary stream of air is mixed with the primary air and coal stream at the exit of the fuel injector to expand the NO x reducing zone, such that NO x occurring within the combustion zone can be decreased.
- the secondary air stream is supplied at the exit of the fuel injector at the central portion of the fuel flow entering the combustion zone, a region of combustion air is created at the central portion of the combustion zone. This region of combustion air creates an internal interface between the primary air/coal stream and the central, secondary stream air stream, thereby forming a high stoichiometric flame surface within the volume of the flame, such that only a small portion of the primary air/coal stream is affected.
- FIG. 1 is a sectional view of an exemplary- embodiment of a fuel injector for a pulverized coal furnace, in accordance with the present invention.
- the fuel injector 10 includes an elongated housing 11 having an inlet end 12 and an outlet end 14.
- the materials of which the fuel injector 10 can be made are conventional and may include various materials capable of withstanding extreme heat, such as iron, various other metals such as carbon steel and stainless steel, ceramic and the like.
- the housing 11 includes an elongated annular wall 16 extending from the inlet end 12 to an outwardly tapering annular wall 18.
- the housing 11 includes an elongated annular wall 20 extending between the outlet end 14 and end 19 of the wall 18, which opposes the outlet end 14 of the fuel injector 10.
- the portions of the injector 10 defined by the walls 16, 18 and 20 are referred to below, respectively, as the entry region 22, the transition region 24 and the nozzle region 26.
- the secondary stream increases the oxygen concentration and heats the primary stream within the injector 10 to create an increased stoichiometry in the primary stream on and around the central axis A of the passageway 28, which in turn increases the stoichiometry of the fuel stream on and around the burner axis within the combustion zone 30.
- the resultant fuel/air mixture on and around the burner axis will more easily gasify or combust once sufficient energy is supplied to initiate the combustion process.
- a further benefit is a shorter flame length.
- the taper and the diameters are selected to maintain the speed of the primary stream constant throughout the passageway 28, or alternatively obtain a selected speed for the fuel stream exiting at the outlet end 14 of the injector 10 which is different than the speed of the primary stream entering at the inlet end 12 of the injector 10.
- the secondary stream is supplied to the injector 110 through the aperture 132, and then flows from the aperture 132 through the hollow tube 154 and into the interior 150 of the distributor 140.
- the conical shape of the interior 150 directs the secondary stream substantially on and around the central axis A of the passageway 28.
- the secondary stream upon exiting the interior 150, interacts with and heats the primary stream, which the distributor 140 has diverted in a manner similar to that described above for the cone 40 of the injector 10, beginning in the entry region 22, and then in the transition and the nozzle regions 24, 26 of the injector 10.
- the secondary stream flows through the tube 154, into the distributor 240 through the aperture 241 and then exits from the interior 150 of the distributor 240 into the passageway 28 in the entry region 22.
- the conical shape of the interior 150 directs the secondary stream substantially along and surrounding the central axis A of the passageway 28.
- the secondary stream upon exiting the interior 150 of the distributor 240, interacts with and heats a portion of the primary stream flowing along and around the central axis of the passageway 28 as the primary stream flows from the entry region into the transition region 24 and then into the nozzle region 26 of the injector 10.
