ABSTRACT:
Method and apparatus for controlling the output emissions of a gas turbine engine provides an emissions combustor wherein the gas is burned locally and then thoroughly mixed with cooler unburned portions while propagating the resulting a very hot flame front is propagated over the whole gas stream flow. The emissions combustor serves to reduce the carbon monoxide content of the output. NOX can be eliminated by steam injection into the engine main combustor in combination with the emissions combustor. Combustion efficiency, which is reduced through the steam injection in the main combustor is recovered through the use of the emissions combustor. The emissions combustor can be placed at numerous locations, either as part of a main combustor staging, downstream of a high pressure turbine, or in a supplementary burner after a power turbine.
