Abstract (en)

[origin: EP0849532A2] To operate the burner (1), of a gas turbine assembly, the auxiliary gas flow (15) is fed in on ignition and on a partial loading of the burner, at a higher pressure than the liquid fuel (2) flow. The auxiliary gas flow is interrupted at the zones of the burner where there is a high loading. When the flow of the auxiliary gas is broken, the liquid fuel is not interrupted. The auxiliary gas is fed to the burner from a pressure vessel or an auxiliary compressor. The auxiliary gas is air, an inert gas such as nitrogen, or an ignition gas such as propane or natural gas.
