(54) | A gas turbine with a catalytic combustor and method of operating such a gas turbine |
(57) The present invention is a method and apparatus for operating a gas turbine that
includes a catalytic combustor. The catalyst in the catalytic combustor is electrically
heated, thereby initiating catalytic combustion without preheating the intake air.
Eliminating the need to preheat the intake air allows removal of the preburner which
otherwise produces an undesirable amount of oxides of nitrogen NOx, especially at start up and low load conditions. |
