Abstract
The gas turbine comprises a compressor, a combustor, and a turbine. The method comprises: compressing air with the compressor and feeding compressed air continuously to the combustor, feeding fuel to the combustor, continuously firing the mixture of fuel and gas in the combustor, feeding combustion gases from the combustor to the turbine, and supplying at least a portion of the total amount of fuel that is supplied to the combustor intermittently.
Claims10
A method for operating a gas turbine comprising a compressor, a combustor, and a turbine, the method comprising:
- compressing air with the compressor and feeding compressed air continuously to the combustor,
- supplying fuel to the combustor,
- continuously firing the mixture of fuel and gas in the combustor,
- feeding combustion gases from the combustor to the turbine,
- supplying at least a portion of the total amount of fuel that is supplied to the combustor intermittently to the combustor, and
- supplying steam intermittently to the combustor where the supply of fuel and steam are varied in a manner timed so as to recover energy from pressure fluctuations caused by the variation in the supply of fuel and steam.
