Claims
- 1. A gas turbine for the combustion of a fuel gas comprising;
- a compressor part;
- a combustion chamber connected to said compressor part;
- an expansion part connected to said combustion chamber;
- a preforming catalytic stage having a catalyst system with a catalytic converter formed essentially of titanium dioxide and including a substance selected from the group consisting of at least one transition-metal oxide and at least one precious metal for converting a hydrocarbon contained in fuel gas into at least one of an alcohol and an aldehyde; and
- a conduit system for drawing off a part of a fuel gas flow, guiding the part of the fuel gas flow through said catalytic stage and subsequently feeding the part of the fuel gas flow back to the fuel gas flow for lowering a catalytic ignition temperature of the fuel gas flow.
- 2. The gas turbine according to claim 1, wherein said preforming stage includes a preheating device for the part of the fuel gas flow, in a flow direction of the part of the fuel gas flow.
- 3. The gas turbine according to claim 1, wherein said catalytic converter is at least one of a honeycomb and a plate-type catalytic converter.
- 4. The gas turbine according to claim 1, wherein said conduit system draws off and guides a maximum of about 25% by volume of the fuel gas flow through said preforming stage.
- 5. The gas turbine according to claim 1, including a catalytic combustion chamber receiving the fuel gas flow.
