The invention relates to a plain jet radial injection fuel nozzle for a gas turbine combustor. The nozzle includes an axially elongate middle tube having a desired diameter. The middle tube is adapted for fuel flow. A fuel exit passage is located circumferentially around the middle tube near its distal end. An axially elongate inner adapted for flow of air or gaseous fuel is inside the middle tube. An axially elongate outer tube is also adapted for flow of air or gaseous fuel. The outer tube is located outisde the middle tube, so as to create a space between the middle tube and the outer tube where fuel flowing through the middle tube and air flowing through the inner and outer tubes can mix to form a fuel/air mixture. The nozzle has an endcap at the distal end of the outer tube. The endcap includes a fuel/air exit passage that permits the fuel/air mixture to exit the nozzle. The nozzle can be adapted to attach to a quarl for providing a fuel/air mixture to a gas turbine combustor.

A plain jet radial injection fuel nozzle for a gas turbine combustor, comprising: an axially elongate middle tube having a distal end and a proximal end, said middle tube being adapted for flow of fuel therethrough; a fuel exit passage located circumferentially around the middle tube near the distal end thereof; an axially elongate inner tube having a proximal end and a distal end, said inner tube being adapted for flow of air or gaseous fuel therethrough, said inner tube located inside said middle tube; an axially elongate outer tube adapted for flow of air or gaseous fuel therethrough, said outer tube having a distal end and a proximal end, said middle tube located inside said outer tube, so as to create a space between said middle tube and said outer tube where fuel flowing through said middle tube and air flowing through said inner and outer tubes can mix to form a fuel/air mixture; and an endcap located on the distal end of said outer tube, said endcap including a fuel/air exit passage that permits said fuel/air mixture to exit said nozzle, said endcap structured to reverse the air flow from the inner tube to oppose the air flow from the outer tube, thereby creating shear forces that atomize fuel flow from the middle tube.
