A combustor in which fuel is introduced into a combustion zone at a first acute angle with respect to the radially outward direction so as to swirl the fuel about the combustor axis, thereby improving the stability of the combustion process. Combustion air is introduced into the combustion zone at a second acute angle with respect to the radially inward direction so as to swirl the air about the combustor axis in the same circumferential direction that the fuel is swirled, with the first and second acute angles being approximately equal. By swirling the combustion air in a manner that is compatible with the swirling of the fuel, noise associated with the combustion process is reduced.

A fuel nozzle assembly having a cylindrical nozzle tip at one end of a fuel delivery tube and a supporting flange at the other end. An air delivery tube, also secured to said support flange, encloses the fuel delivery tube to define an annular air chamber therebetween. A cylindrical face of the nozzle tip is received in an similarly sized and shaped opening in a swirl cap attached to the end of the fuel delivery tube to slideably engage the air delivery tube and the fuel delivery tube and to define a substantially constant radial spaced relationship between the cylindrical nozzle tip and the air delivery tube during variable axial expansion of the fuel delivery tube and air delivery tube. The air delivery tube is secured to the fuel delivery tube by mounting a radially expansive portion of the air delivery tube to the support flange.
