How many reheat stages are there in Rankine cycle?
The Ideal Reheat Rankine Cycle In the ideal reheating cycle, the expansion process takes place in two stages, i.e., the high-pressure and low-pressure turbines.
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.
How many turbine are there in Reheat Rankine cycle?
two turbines
In a reheat cycle, the expansion takes place in two turbines. The steam expands in the high-pressure turbine to some intermediate pressure, then passes back to the boiler, where it is reheated at constant pressure to a temperature that is usually equal to the original superheat temperature.
How many steps are in a Rankine cycle?
four processes
The four processes in the Rankine cycle There are four processes in the Rankine cycle. The states are identified by numbers (in brown) in the T–s diagram. Process 1–2: The working fluid is pumped from low to high pressure.

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.
How do you Reheat Rankine cycle?
What is reheat and regeneration in Rankine cycle?
When the number of reheat stages in a reheat cycle is increased the average temperature?
This side effect can be corrected by reheating the steam, and results in the reheat Rankine cycle. When the number of the reheat stages increases, the expansion and reheat processes approach an isothermal process at the maximum temperature. But using more than two stages is not practical.
What is the effect of reheating on Rankine cycle?
How can we increase the efficiency of Rankine cycle?
Alternative way of increasing the Rankine cycle efficiency is by increasing the boiler operating pressure and thus in a way related with the temperature at which boiling is taking place in the boiler. Thus the thermal efficiency of the cycle increases.
What is the efficiency of a Rankine cycle?
Thermal Efficiency of Rankine Cycle In modern nuclear power plants, which operate the Rankine cycle, the overall thermal efficiency is about one-third (33\%), so 3000 MWth of thermal power from the fission reaction is needed to generate 1000 MWe of electrical power.
What does Rankine cycle mean?
The Rankine cycle is an idealized thermodynamic cycle describing the process by which certain heat engines, such as steam turbines or reciprocating steam engines, allow mechanical work to be extracted from a fluid as it moves between a heat source and heat sink.
How does a Rankine cycle work?
An Organic Rankine Cycle (ORC) uses an organic working fluid that has a boiling point less than that of water to convert low-temperature heat into mechanical work. The mechanical work that is generated can then be converted into electricity.
