摘要： A system and method improves cold start performance of an organic Rankine cycle (ORC) plant. The system includes one or more pumps configured to pump condensed fluid from points of natural accumulation of the condensed fluid within an ORC loop back into a corresponding low pressure liquid storage vessel shortly after shutting down the ORC plant to ensure the start-up routine works properly for the next ORC plant start event. One or more of the pumps can also be configured to pump fluid away from the ORC expansion machine(s) at any time prior to starting the ORC if the fluid is in a liquid phase.

摘要： A waste heat recovery plant control system includes a programmable controller configured to generate expander speed control signals, expander inlet guide vane pitch control signals, fan speed control signals, pump speed control signals, and valve position control signals in response to an algorithmic optimization software to substantially maximize power output or efficiency of a waste heat recovery plant based on organic Rankine cycles, during mismatching temperature levels of external heat source(s), during changing heat loads coming from the heat sources, and during changing ambient conditions and working fluid properties. The waste heat recovery plant control system substantially maximizes power output or efficiency of the waste heat recovery plant during changing/mismatching heat loads coming from the external heat source(s) such as the changing amount of heat coming along with engine jacket water and its corresponding exhaust in response to changing engine power.

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.
