Japanese Patent JPH0159414
Kind Code:
B2
Abstract:
Burner system for gas turbine combustion chambers having a pre-mixing burner with an integrated diffusion burner, where: the pre-mixing burner has a pre-mixing chamber bounded at the downstream end by a flame retention baffle, into which chamber a main fuel nozzle and a feeding device for combustion air open; the diffusion burner has a pilot fuel nozzle arranged in the central region of the flame retention baffle; and where a fuel control device controls the total amount and the partial amounts of the fuel fed to the main fuel nozzle and the pilot fuel nozzle as a function of the load of the gas turbine such that the diffusion burner can be operated exclusively until the idling speed or a small partial load is reached, and thereafter the diffusion burner and the pre-mixing burner can be operated together, characterized especially by the fact that the entire combustion air required for the operation of the diffusion burner can be fed-in exclusively via the pre-mixing chamber, and that the fuel control device controls the total amount and the partial amounts of the fuel supplied such that the pre-mixing burner can be operated exclusively in the upper load range.
