An electricity generation unit 1A includes a combustor 11, a heater 13, and a Rankine cycle circuit 20. The combustor 11 combusts a solid fuel. A combustion gas generated in the combustor 11 passes through a flue 12. The heater 13 contains a heat storage material, and heats the heat storage material by allowing heat exchange to take place between the combustion gas in the flue 12 and the heat storage material. The Rankine cycle circuit 20 has an evaporator 21 that evaporates a working fluid in the Rankine cycle by allowing heat exchange to take place between the heat storage material heated in the heater 13 and the working fluid. With this configuration, stable operation of an electricity generation unit using a combustion gas of a solid fuel is achieved.

摘要:
A combined cycle power plant system and methods of operation so as to minimize consumption of cooling water utilizes exhaust from a combustion turbine to generate steam for power generation in a steam turbine topping cycle. The exhaust steam from the steam turbine topping cycle is utilized to vaporize an organic working fluid in an organic working fluid bottoming cycle, where vaporized organic working fluid expanded across a turbine generates additional power. Exhaust gas from the organic working fluid bottoming cycle is condensed utilizing an air-cooled heat exchanger. Heat exchange bundles of the air-cooled heat exchanger are preferably arranged horizontally relative to the ground to maximize efficiency. Turbine inlet cooling is employed at the combustion turbine to recapture energy lost in the system. A thermal energy storage tank may be utilized in conjunction with the turbine inlet cooling to supply chilling water to the system.
