摘要： A gas turbine engine assembly including an improved apparatus for cooling the combustor (12) to preclude thermal failure of the combustor (12) and to preclude NOx formation. The system includes a liquid pump (40) driven by the turbine shaft (16) and supplying a cooling fluid to an annular cooling chamber (24) defined around the central combustion chamber (22) of the combustor. The cooling fluid is thereby placed in heat exchange relation to the combustor (12) to absorb heat from the combustion products within the combustion chamber and convert the fluid to a relatively higher energy condition, whereafter the fluid in its high energy condition is injected into the combustion chamber (12) for mixture with the combustion products and delivery with the combustion products to the turbine inlet. The cooling liquid may totally fill the annular cooling chamber around the combustion chamber (12) or may partially fill the annular cooling chamber (24), or the cooling fluid arriving at the annular cooling chamber (24) may already be in a gaseous state so that the cooling chamber is totally filled with a vapor (46).

摘要： A combustor 12 for generating combustion products for delivery to a gas turbine 10, said combustor 12 comprising:

a central combustion chamber 22 having one end 12c and defining a central axis;
a burner 26 to deliver products of combustion to said one end 12c of said central combustion chamber 22;
a discharge at the opposite end 12b of said central combustion chamber 22 for delivering combustion products to said turbine 10;
an annular cooling chamber 24 in surrounding relation to said central combustion chamber 22;
an entry opening 12g in said annular cooling chamber 24 for receipt of a cooling fluid, said entry opening 12g being arranged adjacent to said one end 12c of said central combustion chamber 22, said cooling fluid forming a bath 44 within said annular cooling chamber 24 to absorb thermal energy from said combustion products being within said central combustion chamber 22; and
a plurality of apertures 12e providing communication between said annular cooling chamber 24 and said central combustion chamber 22 proximate said opposite end 12b of said central combustion chamber 22,
wherein the burner 26 is disposed axially adjacent to said one end 12c of said central combustion chamber 22 and said cooling chamber 24.
