摘要： A gas turbine intercooler operates to heat a predetermined organic fluid via heat generated by the gas turbine. The heated organic fluid remains in a partially evaporated or non-evaporated liquid phase to provide a heated organic fluid that reaches a state of saturation with a vapor quality less than unity. An expansion machine expands the heated organic fluid via a Tri-Lateral Flash cycle to increase the vapor quality and generate electrical power therefrom.

摘要： A pressure sensor measures an organic Rankine cycle (ORC) working fluid pressure in front of a radial inflow turbine, while a temperature sensor measures an ORC working fluid temperature in front of the radial inflow turbine. A controller responsive to algorithmic software determines a superheated temperature of the working fluid in front of the radial inflow turbine based on the measured working fluid pressure and the measured working fluid temperature. The controller then manipulates the speed of a working fluid pump, the pitch of turbine variable inlet guide vanes when present, and combinations thereof, in response to the determined superheated temperature to maintain the superheated temperature of the ORC working fluid in front of the radial inflow turbine close to a predefined set point. The superheated temperature can thus be maintained in the absence of sensors other than pressure and temperature sensors.
