Burner Apparatus, Gas Turbine Engine and Cogeneration System

摘要

A burner apparatus comprising an inner tube 2 defining a second channel A2 and an outer tube 3 defining a first channel A1 surrounding the inner tube 2, oxygen-containing gas supplying means for supplying oxygen-containing gas A to the first channel A1 and the second channel A2, and gas supplying means for supplying fuel gas G to the first channel A1 and the second channel A2, either the first channel A1 or the second channel A2 being used as a main combustion channel A1 and the other being used as a pilot combustion channel A2, the main combustion channel A1 and the pilot combustion channel A2 receiving the supply of fuel gas G for combusting it;
wherein the main combustion channel A1 includes a mixing promoting member 36 against which the fuel gas G discharged from the first supply opening 5 into the main combustion channel A1 is collided to be diffused in the main combustion channel A1 or the pilot combustion channel A2 includes a mixing promoting member 36 against which the fuel gas G discharged from the second supply opening 7 for supplying the fuel gas G into the pilot combustion channel A2 is collided to be diffused in the pilot combustion channel A2.
