    摘要: A compressed air energy storage and power generation device 2 includes a compressor 10, an accumulator tank 12 and an expander 14. The compressor 10 compresses air in such a manner that a motor 30 is driven by renewable energy. The accumulator tank 12 stores the air thus compressed. The expander 14 is driven by the compressed air. A generator 28 is mechanically connected to the expander 14. The device 2 further includes: a first heat exchanger 18 that recovers compressed heat; a heat medium tank 20 that stores a heat medium; and a second heat exchanger 22 that heats the compressed air. The device 2 further includes a first pump 46 and a control device 48a. The first pump 46 adjusts an amount of the heat medium to be supplied to the first heat exchanger 18. The control device 48a controls the first pump 46 to adjust the amount of heat medium to be supplied to the first heat exchanger 18 so as to maintain the heat medium, which is stored in the heat medium tank 20, at a predetermined first temperature. In this way, there is provided such a compressed air energy storage and power generation device 2 capable of highly maintaining charge/discharge efficiency.

    摘要: A heat energy recovery system includes an evaporator, a superheater, an expander, a power recovery device, a condenser, a pump, and a controller. The controller includes: an engine load calculation section; a maximum rotation speed determination section for determining a maximum rotation speed of the pump which is obtained when a pinch temperature reaches a target pinch temperature, based on a relational expression representing a relationship between the engine load and the maximum rotation speed, and an engine load; and a rotation speed regulation section for regulating the rotation speed of the pump in such a way as to allow the degree of superheat of the working medium flowing into the expander to be equal to or greater than a reference value, and to allow the rotation speed to be equal to or less than a maximum rotation speed determined by the maximum rotation speed determination section.

    摘要: A pulsed pressure, heat recovery system is provided. The heat recovery system includes a pressure vessel for holding a vaporisable first fluid. The pressure vessel contains a heat exchanger, and provides communication to the heat exchanger for flow of a heated second fluid therethrough. The heat exchanger enables heat transfer from the heated second fluid to vaporise the first fluid. The heat recovery system further includes a flow loop for the first fluid extending from an outlet of the pressure vessel to an inlet to the pressure vessel. The flow loop has in flow series: a first non-return valve, a turbine and a second non-return valve. The first non-return valve allows the vaporised first fluid to flow from the pressure vessel to the turbine when the pressure of the vaporised first fluid in the pressure vessel exceeds a predetermined limit. The turbine extracts energy from expansion of the vaporised first fluid flowing therethrough. The second non-return valve prevents flow reversal around flow loop between the turbine and the inlet. The heat recovery system alternates between periods in which the pressure of the vaporised first fluid in the pressure vessel exceeds the predetermined limit and energy is extracted by the turbine, and periods of pressure build up in the pressure vessel when the pressure of the first fluid in the pressure vessel is below the predetermined limit.

    摘要: A turbine-generator device for use in electricity generation using heat from industrial processes, renewable energy sources and other sources. The generator may be cooled by introducing into the gap between the rotor and stator liquid that is vaporized or atomized prior to introduction, which liquid is condensed from gases exhausted from the turbine. The turbine has a universal design and so may be relatively easily modified for use in connection with generators having a rated power output in the range of 50 KW to 5 MW. Such modifications are achieved, in part, through use of a modular turbine cartridge built up of discrete rotor and stator plates sized for the desired application with turbine brush seals chosen to accommodate radial rotor movements from the supported generator. The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.
