Abstract:
1. A gas turbine capable of operating in a highly diluted mode, the gas turbine comprising: a compressor adapted to compress oxidant; a combustion chamber adapted to accept the compressed oxidant and including an exit means for flue gas; a turbine; and flue gas re-circulation means for re-circulating the flue gas from the combustion chamber and mixing the flue gas with the compressed oxidant from the compressor to provide a highly diluted mode of combustion with a non-visible flame with a flue gas re-circulation rate of from 100% to 200%; wherein the flue gas re-circulation means is also for mixing the re-circulated flue gas with a premixed stream of fuel and oxidant before the premixed stream enters the combustion chamber.
