PROBLEM TO BE SOLVED: To provide a combustor for a gas turbine engine. SOLUTION: A low emission turbine includes a reverse flow can-type combustor 102 generally including primary and secondary fuel delivery systems which are independently controlled to produce low CO, UHC and NOx emissions at design set point and at conditions other than design set point. The reverse flow can-type combustor 102 generally includes a swirler and mixer assembly 140 within the combustor, wherein each swirler and mixer assembly 140 comprises an array of annularly arranged swirlers and mixers including the primary and secondary fuel delivery systems, and the primary and secondary fuel delivery systems are independently controlled. The can-type combustor including fluid passageways 142, 220 that allow the fluid to perpendicularly impinge on a backside of a heat shield 136, is also disclosed. COPYRIGHT: (C)2005,JPO&NCIPI
