Abstract
A gas turbine (A, B, C) is provided that includes at least a compressor (1), a combustor (2), and a turbine (3) and combusts ammonia serving as fuel in the combustor (2), including a reducing agent supply device (6) configured to supply a reducing agent for reducing nitrogen oxides in a combustion gas to at least one of: a combustion gas flow path between the combustor (2) and the turbine (3); and the turbine (3).
Claims6
A gas turbine that includes at least a compressor, a combustor, and a turbine and combusts ammonia serving as fuel in the combustor, comprising:
- a water vapor circulator configured to recover water vapor generated by combustion of the ammonia to circulate and supply the water vapor to the combustor,
- wherein the water vapor circulator includes:
- a heat exchanger that condenses the water vapor contained in exhaust gas discharged from the turbine;
- a gas-liquid separator that separates water condensed by the heat exchanger and residual gas of the exhaust gas;
- and
- a water pump that supplies the water separated by the gas-liquid separator to the heat exchanger,
- wherein the heat exchanger vaporizes the water supplied from the water pump by heat exchange with the exhaust gas and supplies the water vapor to the combustor, and wherein the gas turbine further comprises a first mixer configured to mix at least a part of the ammonia before being supplied to the combustor as the fuel with the water supplied from the water pump to the heat exchanger.
A gas turbine that includes at least a compressor, a combustor, and a turbine and combusts ammonia serving as fuel in the combustor, comprising:
- a reducing agent supply device configured to supply a reducing agent for reducing nitrogen oxides in a combustion gas to a combustion gas flow path between the combustor and the turbine.
