<p>The synthesis gas-based fuel system comprises a main synthesis gas pipe (9), which branches off a gasification device and ends at a transfer point (40), where the pipe is connected to a burner, a means by which a calorific value detected by a calorific value measuring device is determined by a control valve, and a heat exchanger arranged in a fuel line. In the main synthesis gas pipe, a device (33) for admixing a second fuel and a thorough mixing device (34) are arranged. The device for admixing second fuel is arranged downstream to the thorough mixing device. The synthesis gas-based fuel system comprises a main synthesis gas pipe (9), which branches off a gasification device and ends at a transfer point (40), where the pipe is connected to a burner, a means by which a calorific value detected by a calorific value measuring device is determined by a control valve, and a heat exchanger arranged in a fuel line. In the main synthesis gas pipe, a device (33) for admixing a second fuel and a thorough mixing device (34) are arranged. The device for admixing second fuel is arranged downstream to the thorough mixing device in the flow direction of a synthesis gas directly above the area of transfer point. A fuel line flows into the device for admixing second fuel and a control valve is switched in the fuel line. The calorific value measuring device is arranged in flow direction of the synthesis gas, downstream to the through mixing device. The thorough mixing device is filter. The device for admixing second fuel is a natural gas mixing device. Independent claims are included for: (1) a gas- and steam turbine plant; and (2) a method for operating a synthesis gas-based fuel system for rapid load changes in a synthesis gas-operated gas turbine.</p> |
