Fuel feed for gas turbines having an annular combustion chamber

摘要

The object of the invention is to create a simple and compact fuel feed for a gas turbine having an annular combustion chamber. In addition, the operational reliability of the gas turbine is to be improved. According to the invention, this is achieved when only one central main-gas feed line (15) and one central pilot-gas feed line (16) are connected to the annular combustion chamber (1). A main-gas ring line (13) and a pilot-gas ring line (14) are formed in the interior of the gas-turbine casing (5) or a burner hood (3) known per se. These ring lines (13, 14) are connected upstream to the main-gas feed line (15) and the pilot-gas feed line (16) respectively and downstream to the annular combustion chamber (1). (FIG. 1)
