Burner with fluid oscillator for gas turbine and gas turbine with at least one said burner

摘要

The present invention relates to a burner having a premixing flow path (68), wherein the premixing flow path is partitioned by a wall radially outward and used for premixing fuel and air during operation , A burner lance (72, 94) and a plurality of fuel injectors are arranged in the premixing flow path, the fuel injector extends from the burner lance (72) in the direction of the wall , And a fuel nozzle (80, 80a, 80b). The burner enables reduction of emissions of hazardous substances during operation or reduction of pressure fluctuations. To that end, the fuel supply device comprises at least one fluid oscillator (85) having an interaction chamber (26), the inlet (28) of the interaction chamber being connected to the fuel conduit (82 ), The first exhaust conduit (86) of the interaction chamber extends to at least a first fuel nozzle (80a) and the second exhaust conduit (88) extends to at least a second Each of said discharge conduits extending to a fuel nozzle (80b), said fluid oscillator including a feedback conduit (38a, 38b) for each said discharge conduit, said feedback conduit having at least one In the region downstream of the fuel nozzle, into the respective discharge conduit and at the other end into the interaction chamber inlet region (30).
