Gas turbine assembly has non-catalytic preliminary combustion stage upstream of catalytic first burner stage; burner of preliminary combustion stage is configured as diffusion burner

摘要

The gas turbine assembly has at least one compressor (12), a turbine (4) and at least one combustion chamber with a catalytic first burner stage (2), a downstream, non-catalytic second burner stage (6) and an upstream preliminary combustion stage (1). The preliminary combustion stage is a non-catalytic stage. A burner of the preliminary combustion stage is configured as a diffusion burner.
