ABSTRACT:
A combustion chamber for a gas turbine is provided with a prechamber connected at the input end of the flame tube. The dimensions of the flame tube and prechamber, and the location of the air inlet openings are selected so that the flame in the flame tube flashes back and burns as a stable rich flame in the prechamber when the turbine is in a high-load condition. The result is a variation in the combustion properties of the chamber which reduces pollutant emission levels over a wide range of engine load conditions.
