Catalytically operating burner

A process of using a catalyzer structure, comprising the steps of:

• providing a catalyzer structure which is divided into (i) an inlet zone including an inlet end of the catalyzer structure and which is catalytically inactive or inert, (ii) an outlet zone including an outlet end of the catalyzer structure and which is catalytically inactive or inert, and (iii) an intermediate zone which is catalytically active and located between the inlet zone and the outlet zone along a flow direction, the catalyzer structure including a heat-resistant carrier material that extends continuously from the inlet end to the outlet end of the catalyzer structure and that forms the walls of several adjoining channels that pervade the catalyzer structure in the longitudinal direction of the catalyzer structure and enable a gas stream with injected fuel to flow through the catalyzer structure, wherein the walls are coated with a catalyst in such a way that at least some of the channels have at least one catalytically active zone and at least two catalytically inactive or inert zones in the flow direction and wherein between the inlet end and the outlet end of the catalyzer structure communicating openings are constructed in the walls, through which the adjoining channels are communicating with each other, in a catalytically operating burner;
• and
• flowing the gas stream with injected fuel through the catalyzer structure whereby the catalyst initiates a combustion reaction of the gas stream with injected fuel inside the catalyzer structure;
• a stabilization zone being arranged downstream from the catalyzer structure, and which changes into a final combustion zone in which the actual combustion reaction of the gas stream with injected fuel or a homogenous gas phase reaction takes place, wherein the hot combustion gases generated in the final combustion zone by the homogenous gas phase reaction are fed to a downstream turbine of the gas turbine system.
