Device for burning fuel in air for gas turbines

摘要

The device contains an annular channel (4), and a spin grid (9) for superimposing a spin onto the flow. A radially outward lying part of the flow is delayed relative to other parts of the flow by a choke ring (13) arranged in the annular channel and extending over a radially outward lying part of the annular channel. The choke ring, which is mounted upstream of the spin grid, consists of rods mounted in the annular channel.
