T–s diagram of a typical Rankine cycle operating between pressures of 0.06 bar and 50 bar. Left from the bell-shaped curve is liquid, right from it is gas, and under it is saturated liquid–vapour equilibrium. There are four processes in the Rankine cycle. The states are identified by numbers (in brown) in the T–s diagram.
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.
Honda also develops a module based on a Rankine Cycle to improve overall efficiency of hybrid vehicles, by recovering the heat of the engine and turning it into electricity for the battery pack. In the US highway cycle, the Rankine cycle system regenerated three times as much energy as the vehicle's regenerative braking system.
Rankine cycle – Model that is used to predict the performance of steam turbine systems; Organic Rankine cycle – Variation on the Rankine thermodynamic cycle; Stirling engine – Closed-cycle regenerative heat engine; Absorption refrigerator – Refrigerator that uses a heat source; Boiler – Closed vessel in which fluid is heated
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 ...
The cycle 1-2-3-4-1 which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking place in the high temperature region. The cycle a-b-c-d-e-f-a which is the Rankine steam cycle takes place at a lower temperature and is known as the bottoming cycle.
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).
"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 ...
