Explanation:
Regenerative feed heating cycle is a type of steam power plant cycle that is designed to increase the efficiency of the cycle by using a portion of the steam that is extracted from the turbine to heat the feedwater before it enters the boiler. The number of stages of regeneration in a regenerative feed heating cycle depends on various factors, including the initial pressure and temperature of the working fluid.
Effect of Initial Pressure and Temperature:
The economic number of stages of regeneration in a regenerative feed heating cycle increases as the initial pressure and temperature increase. This is because a higher initial pressure and temperature result in a greater temperature difference between the extracted steam and the feedwater, which allows for more heat transfer to occur. As a result, more stages of regeneration are needed to achieve the desired feedwater temperature.
Other Factors:
Other factors that can affect the number of stages of regeneration include the condenser pressure, the amount of steam extracted from the turbine, and the heat transfer coefficients in the regenerative heat exchangers.
Conclusion:
In summary, the economic number of stages of regeneration in a regenerative feed heating cycle increases as the initial pressure and temperature increase. This is because a higher initial pressure and temperature result in a greater temperature difference, which allows for more heat transfer to occur.
