Regenerative Feed Heating Cycle
A regenerative feed heating cycle is a process in which steam is extracted from the turbine at various stages and is used to preheat the feed water before it enters the boiler. This cycle helps in improving the cycle efficiency and reduces the fuel consumption.
Economy of Regenerative Feed Heating Cycle
The economy of a regenerative feed heating cycle depends on the number of extraction points from the turbine. The greatest economy is achieved when steam is extracted from several places in different stages of the steam turbine.
Explanation
When steam is extracted from several places in different stages of the steam turbine, it helps to reduce the temperature of the steam at each stage, which in turn helps to increase the temperature difference between the steam and the feed water. This temperature difference results in a higher rate of heat transfer and hence improves the cycle efficiency.
If steam is extracted from only one suitable point of the steam turbine, then the temperature difference between the steam and the feed water will be less, resulting in a lower rate of heat transfer and hence lower cycle efficiency.
Extracting steam only from the last stage of the steam turbine or only from the first stage of the steam turbine will also result in a lower cycle efficiency as the temperature difference between the steam and the feed water will be less.
Conclusion
In conclusion, the greatest economy in a regenerative feed heating cycle is achieved when steam is extracted from several places in different stages of the steam turbine. This helps to improve the cycle efficiency and reduces the fuel consumption.
