The ideal practical cycles for IC Engines are Otto cycle (for Petrol and gas engines) and Diesel cycle (for Diesel or oil engines). Similarly the ideal practical cycle for steam—is the RankineCycle. Figure 22.1 shows saturated cycle for both Carnot and Rankinecycle. Carnot cycle is 1'-2-3-4′ and Rankinecycle 1-2-3-4.

A reheat-and-regenerating type thermal power plant (A) using Rankinecycle has a water feed bypass (BW) which suppies high temperature fluid (28) produced in a large incineration plant (27) to a heat exchanger (29) and by which confluent feed water (Wg) resulting from the confluence of separated condensed-water (32), separated low temperature feed water (33), separated medium temperature feed.
However, the simple Rankinecycle ended up giving us unrealistic values so we decided upon a reheat-regenerativeRankinecyclewith an open water feeder. Open feedwater heaters are simple and inexpensive and have good heat transfer characteristics. ... We then poured the hot solution containing dissolved aspirin into approximately 40cm3 of.
3. Heat transfer in the ideal RankineCycle relies on phase change, a very efficient way to store and release energy. The working fluid is usually water/steam. During the cycle, the properties of the working fluid change as below with associated heat/work exchanges. h (kJ/kg) P (kPa) T (oC) s (kJ/kg-k) q or w (kJ/kg) 1Æ2 Small increase h1 = hf ...
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 called "direct-contact heating". The
RANKINE CYCLE: THE IDEAL CYCLE FOR VAPOR POWER CYCLES Many of the impracticalities associated with the Carnot cycle can be eliminated by superheating the steam in the boiler and condensing it completely in the condenser. The cycle that results is the Rankine cycle, which is the ideal cycle for vapor power plants. The ideal Rankine cycle does ...
This blog article is a follow up for the earlier blog "Coupled Optimization of Preliminary Design Geometry of Low Flow Steam Turbine with Curtis Stage Layout and RankineCycle Parameters", which considers more complicated case of coupled optimization of regenerativeRankinecycle and 2 stage turbine geometry with change from partial to full admission flow.
practical regenerative Rankine cycles, open and closed feed water heaters. Reheat Rankine cycle. Vapour power cycles are used in steam power plants. In a power cycle heat energy (released by the burning of fuel) is converted into work (shaft work), in which a working fluid repeatedly performs a succession of processes. In a vapour power cycle, the working fluid is water, which
