In order to return the steam to the high-pressure of the boiler to continue the cycle, the low- pressure steam leaving the turbine at state 2 is first condensed to a liquid at state 3 and then pressurized in a pump to state 4. The high pressure liquid water is then ready for its next pass through the boiler to state 1 and around the Rankine Get Price
