  • Combustor cooling for gas turbine engines
    Patent number: 6176075
    Abstract: A gas turbine engine assembly including improved means for cooling the combustor to preclude thermal failure of the combustor and to preclude NOx formation. The system includes a liquid pump driven by the turbine shaft and supplying a cooling fluid to an annular chamber defined around the central combustion chamber of the combustor. The cooling fluid is thereby placed in heat exchange relation to the combustor 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 for mixture with the combustion products and delivery with the combustion products to the turbine inlet.
    Type: Grant
    Filed: December 2, 1997
    Date of Patent: January 23, 2001

  • Combustor cooling for gas turbine engines
    Patent number: 5694761
    Abstract: A gas turbine engine assembly including improved means for cooling the combustor to preclude thermal failure of the combustor and to preclude NO.sub.x formation. The system includes a liquid pump driven by the turbine shaft and supplying a cooling fluid to an annular chamber defined around the central combustion chamber of the combustor. The cooling fluid is thereby placed in heat exchange relation to the combustor 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 for mixture with the combustion products and delivery with the combustion products to the turbine inlet.
