Abstract: A combined heat and power system is provided with a Rankine cycle passage, a heat medium passage, an evaporator, an expander, a condenser, a pump, a temperature sensor, a sensor, and a controller. The evaporator receives the heat from the heat medium to heat a working fluid. The temperature sensor detects the temperature of the heat medium after radiating heat for heating the working fluid. The sensor detects the pressure of the working fluid flowing between the outlet of the evaporator and the inlet of the expander. The controller adjusts the rotation speed of the pump based on the temperature detected by the temperature sensor, and in addition, adjusts the rotation speed of the expander based on the pressure detected by the sensor.

Abstract: An air cooling unit is an air cooling unit used in a Rankine cycle system and includes an expander and a condenser. The expander recovers energy from a working fluid by expanding the working fluid. The condenser cools the working fluid using air. The air cooling unit includes a heat-transfer reducer that reduces heat transfer between the expander and an air path.

Abstract: 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.

Abstract: A power generation control system includes a converter and a controller. The converter controls a generator of a Rankine cycle system, the Rankine cycle system including an expander, the generator, which is interconnected to the expander, a pump which feeds a working fluid, and an evaporator which evaporates a working fluid. The controller causes the converter to execute, in at least one of a startup operation and a shutdown operation of the Rankine cycle system, first control in at least one of a startup operation and a shutdown operation of the Rankine cycle system such that the expander is prevented from expanding a working fluid if the working fluid at an outlet of the evaporator contains a liquid component while the pump is operating.
