Abstract

A gas turbine and a burner to be used for all gas turbines for the catalytically induced combustion of a fuel, include a flow duct and a main burner having a fuel outlet. A catalytic supporting burner has a fuel outlet in the flow duct upstream of the fuel outlet of the main burner, as seen in the flow direction of the fuel, for stabilizing the main burner along with catalytic combustion of a pilot fuel stream. A marked reduction in nitrogen oxide emission is achieved by replacing a diffusion pilot flame with a catalytic supporting burner.
