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： In one embodiment, a waste heat recovery system includes a Rankine cycle system that circulates a working fluid that absorbs heat from exhaust gas. The Rankine cycle system includes an evaporator that may transfer sensible heat from the exhaust gas to the working fluid to produce cooled exhaust gas. The Rankine cycle system also includes an economizer that may transfer latent heat from the exhaust gas to the working fluid. The economizer is a carbon steel heat exchanger with a corrosion resistant coating.
