Abstract
Each combustor for a gas turbine includes a fuel supply line for supplying fuel to a plurality of nozzles in the combustor. A remotely controlled valve has a valve member movable between valve-open and valve-closed positions. In a valve-closed position, fuel is supplied to a first group of one or more nozzles of the combustor, while fuel is cut off to a second group of one or more nozzles of the combustor. In a valve-open position, fuel is supplied to all nozzles of the combustor. By positively and selectively actuating the valve, the fuel/air ratio of the nozzles supplied by the fuel is increased to enhance flame stability.
