Abstract
A combustor system for a gas turbine is disclosed in which fuel is mixed with an air stream entering the combustor and is then burned, and the resulting combustion air stream is fed downstream from the combustor to a turbine. A quick and efficient mixing of the air stream and fuel is achieved in that the combustor has an annular diffuser into which the air stream enters. Downstream from the diffuser and communicating with it, at least one essentially annular, toroidal chamber is provided. Mixing pipes extend downstream from the annular, toroidal chamber and are distributed over the periphery of the toroidal chamber. Downstream from the mixing pipes, an annular combustion chamber is provided into which the mixing pipes merge.
