Abstract:
1. An organic Rankine cycle (ORC) plant comprising: a boiler configured to receive heat from an external source and to further receive a liquid stream and to generate a vapor stream there from; an expander configured to receive the vapor stream and to generate power and an expanded stream there from, wherein the expander comprises an input fluidically coupled directly to a first valve, and further comprises an output fluidically coupled directly to a second valve; a condenser comprising a first input configured to receive the expanded stream and to generate the liquid stream there from, the condenser further comprising a second input; and at least one condensation fluid feedback pump, the at least one condensation fluid feedback pump comprising an input fluidically coupled directly to both the first valve and the second valve, and further comprising an output fluidically coupled directly to the condenser second input, wherein the liquid stream and the vapor stream together form a closed ORC loop, and further wherein the at least one condensation fluid feedback pump is configured to pump condensed fluid from a plurality of points of natural accumulation of the condensed fluid in the ORC loop directly into the condenser via the condenser second input.
