Abstract:
A gas turbine engine for generating electricity with low NOx emissions comprising:a turbine system for providing rotational energy; a compressor system for providing compressed air connected to said turbine system; a linear shaft connecting said turbine system to said compressor system; a vertically oriented combustion system connected in fluid communication with said compressor system and said turbine system for providing combustion gases for driving said turbine system; said combustion system comprising a combustion generating section for generating combustion gases, a mounting system for attaching said combustion generating system to said engine, and a plenum chamber for receiving said combustion gases; said combustion generating section including a plurality of dual stage, dual mode combustors having low NOx emissions that are in communication with each other, each combustor containing a plurality of fuel nozzles, an upstream/premix combustion chamber and a downstream/secondary combustion chamber separated from said premix chamber by a venturi section; said mounting system for a combustion generating section including a silo dome, upper silo case, and inner dome liner; said silo dome and said inner dome liner each contain a plurality of openings in a circular array for accepting said dual stage, dual mode combustors; said mounting system connected to said plenum chamber, the output of said plenum chamber connected to said turbine section through an annular 360 degree ring to said turbine section; said combustion generating system where in the combustion process of mixing fuel and air and igniting the mixture is contained within both stages of said dual stage, dual mode combustor such that the hot combustion gases exiting each of said combustors mixes in said plenum chamber prior to entry into said turbine system.
