What is a Reheat Rankine cycle?
A Reheat Rankine Cycle is a Superheat Rankine Cycle that uses two turbines to make it possible to operate the condenser at a low pressure and still maintain a very high quality at the turbine effluent. Boiler – heat added at constant pressure. Boiler – heat added at constant pressure.
What is difference between ideal Rankine cycle and actual Rankine?
Thus the efficiency of the actual Rankine cycle is far lower than the ideal Rankine cycle efficiency….Difference Between Ideal and Actual Rankine Cycle.
| Rankine Cycle Representation is as follows on P-v and T-s diagrams: | |
|---|---|
| Ideal Rankine Cycle | 1-2′-b-3′-4′-1 |
| Actual Rankine Cycle | 1-2-b-3-4-1 |
What is the difference between a Rankine cycle?
It gives highest efficiency between given temperature difference. As I told Rankine cycle is an ideal vapor power generation cycle used in steam turbine….Difference between Carnot Cycle and Rankine cycle:
| Sr. No. | Carnot Cycle | Rankine Cycle |
|---|---|---|
| 5. | Carnot cycle is an ideal cycle for heat engine. | It is an ideal cycle for vapor power engine. |
What is reheat and regeneration in Rankine cycle?
Reheating of steam improved the thermal efficiency of the plant, net work output of turbine, reduction in blade erosion (or quality of steam improve). By regeneration thermal efficiency of the plant can be increased but it does not affect work output from turbine.
What is ideal regenerative cycle?
In an ideal regenerative Rankine cycle, steam enters the turbine at the boiler pressure and expands isentropically to an intermediate pressure. Some steam is extracted at this state and routed to the feedwater heater, while the remaining steam continues to expand isentropically to the condenser pressure.
What is reheat and regeneration in Rankine Cycle?
What is the difference between ideal and actual cycle?
The largest difference between the two diagrams is the simplification of the intake and exhaust strokes in the ideal cycle. In the exhaust stroke, heat Qout is ejected into the environment. In a real engine, the gas leaves the engine and is replaced by a new mixture of air and fuel.
What is reheat regenerative cycle?
Reheat of reheat regenerative steam power cycle increases its efficiency by increasing the average temperature of heat reception. The invention applies reversible reheating in addition to the regular reheating and uses smaller temperature differences across feed water heaters than the regular cycle.
