  • Method of controlling bypass air split to gas turbine combustor
    Patent number: 7549292
    Abstract: Disclosed herein is a method for controlling a bypass air split for a gas turbine combustor, the method comprising determining a target exhaust temperature, wherein the target exhaust temperature is based on at least one parameter of a group of parameters consisting of low pressure turbine speed, high pressure turbine speed, inlet guide vane angle, and bypass valve air split. Using the target exhaust temperature to calculate a required percentage of bypass air split based on maintaining maximum CO levels or minimum NOx levels. And, applying the required percentage of bypass air split to control a position of the bypass air valve.

  • MULTIPLE VENTURI TUBE GAS FUEL INJECTOR FOR A COMBUSTOR
    Publication number: 20060156730
    Abstract: A gas fuel injector includes a first header plate; a second header plate spaced downstream from the upstream header plate; and a plurality of venturi tubes arranged in rows and sealably secured to the first and second header plates. Each of the venturi tubes includes an inlet section, a throat section and an exit. The exit is shaped into a pattern that reduces space between each of the venturi tubes at the exit of each of the plurality of venturi tubes.
