    摘要: A control system includes a temperature sensor communicatively coupled to an exit of an expander of an expansion system and configured to detect temperature of the working fluid flowing through the exit of the expander. A pressure sensor is communicatively coupled to the exit of the expander and configured to detect pressure of the working fluid flowing through the exit of the expander. A controller is configured to receive output signals from the temperature sensor and the pressure sensor and control operation of one or more components of the expansion system so as to control the thermodynamic conditions at the exit of the expander while driving a quality of vapor of the working fluid at the exit of the expander towards a predetermined degree of superheat.

    摘要: A waste heat recovery system includes at least two integrated rankine cycle systems coupled to at least two separate heat sources having different temperatures. The first rankine cycle system is coupled to a first heat source and configured to circulate a first working fluid. The second rankine cycle system is coupled to at least one second heat source and configured to circulate a second working fluid. The at least one second heat source includes a lower temperature heat source than the first heat source. The first and second working fluid are circulatable in heat exchange relationship through a cascading heat exchange unit for condensation of the first working fluid in the first rankine cycle system and evaporation of the second working fluid in the second rankine cycle system.
