Abstract: A method of operating an axial stage combustion system in a gas turbine engine (12) including an EGR system (14) that extracts a portion of exhaust gas produced by the gas turbine engine (12) to a second axial stage of a combustor (18). The extracted exhaust gas is provided at an elevated temperature to a group of injector nozzles (50) at the second axial stage (34) of the combustor (18). A secondary fuel supply line (34) extends to an inlet on each of the injector nozzles (50), and the fuel is mixed with the exhaust gas within the injector nozzles (50) and the mixture of fuel and exhaust gas is injected into the second axial stage (34) of the combustor (18).

Abstract: A method to reduce mercury in gas emissions from the combustion of coal is disclosed. Mercury emissions can be reduced by staging combustion process and/or reducing boiler excess oxygen. Fly ash formed under combustion staging conditions is more reactive towards mercury than fly ash formed under typical combustion conditions. Reducing boiler excess oxygen can also improve ability of fly ash to adsorb mercury.

The burner is provided with a plurality of fuel gas inlets for enabling manipulation of the flame shape and combustion characteristics of the burner, based upon variation in the distribution of fuel gas between the various fuel gas inlets.A combination pilot and flame holder for a burner, such as may be used in process heaters and furnaces for refineries, chemical plants and the like, is also provided. The pilot is mounted atop a supply pipe for premixed fuel and air, which is positioned in the bore of a burner quarl. The pilot includes a radially outwardly extending flange which is upstream of a surface combustion flame holder for establishing a radially directed surface combustion flame.The present invention also provides a low-emissions burner and pilot system for use in such process heaters and furnaces.
