where the combustor 30 and the recuperator 40 are combined in a single integral unit 80 the combustor 30 shown in fig2 is a reverse flow combustor where the compressed inlet air 12 flows counter to the high temperature exhaust gas 56 the compressed inlet air 12 enters the combustor housing 32 near the exhaust end of the combustion chamber 51 of the combustor 30 the counter flowing compressed inlet air 12 provides cooling to the combustion chamber 51 the combustion chamber 51 is divided into three zones a prechamber zone 52 a secondary zone 53 and a dilution zone 54 the compressed inlet air 12 is divided into at least two portions a first portion entering the dilution zone 54 through dilution air inlets 60 a second portion if needed entering the secondary zone 53 through secondary air inlets not shown a third portion providing mixing air 62 to a mixing plate or swirler 50 where fuel 15 and mixing air 62 are mixed prior to entering the prechamber zone 52 where combustion occurs an ignitor 33 is provided in the swirler 50 to initially ignite the mixed fuel and air in the combustion chambers shown in fig2 and 5 compressed inlet air 12 is not provided to the secondary zone 53 this reduces the production of co in the combustion chamber and allows the present gas turbine apparatus to meet current environmental limitations on co emissions without the use of additional post combustion.
