The regenerative Rankine cycle is so named because after emerging from the condenser (possibly as a subcooled liquid) the working fluid is heated by steam tapped from the hot portion of the cycle. On the diagram shown, the fluid at 2 is mixed with the fluid at 4 (both at the same pressure) to end up with the saturated liquid at 7. This is ...
A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system ...
T-s diagram for the ideal/real ORC. The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, [3] screw, [4] scroll, [5] or other expander), and then through a condenser heat exchanger where it is finally re-condensed.
"Schoell Cycle" is the name given by inventor Harry Schoell to his implementation of the Rankine cycle. The primary patent for the engine calls it a "Heat regenerative engine" [ 34 ] In the Rankine cycle, water is pumped to high pressure, heated to produce steam, expanded in an engine producing mechanical work then heat is removed to condense ...
English: The layout of the water circuit inside a plant based on a Rankine cycle, using superheating (heating of dry steam downstream of the boiler) and reheating (heating of steam in the midst of its expansion in the turbine).
