Abstract
A structure for fuel nozzle suitable for use in an industrial combustion system and having reduced fouling and coking is disclosed. The fuel nozzle has a fuel inlet, a bore and an outlet port. The structure of the fuel nozzle provides improved mixing of the fuel flow through a bore of the nozzle and pressure drops at an outlet of the nozzle.
Claims30
A fuel nozzle for an industrial combustion system, the fuel nozzle comprising:
- an elongated body defining a fuel inlet port at a first end and terminating in tip at a second end, the elongated body having:
- an interior surface defining a bore extending longitudinally in the elongated body from the inlet port to the tip such that the interior surface has a longitudinally-extending portion and an interior-tip portion;
- at least one ridge defined on the longitudinally-extending portion of the inner surface;
- and
- an exterior surface having a side portion and an exterior-tip portion,
- wherein the tip defines a fuel port having an inner orifice at the interior-tip portion and an outer orifice at the exterior-tip portion;
- and
- wherein the inlet port, bore and inner orifice are in fluid flow communication so that at least a portion of fuel entering the inlet port flows through the bore, through the inner orifice and out the outer orifice.
