How does a chemical fuel differ from the nuclear fuel?
>>The chemical fuel is different from nuclear fuel in the sense that in combustion processes there is no possibility of emission of radioactive elements such as X-rays ,y-rays and any others radioactive elements. There is less care required while working with chemicals fuels.
What do you mean by Rankine cycle?
>>It is the theoretical cycle on which the same turbine works.
How can the Rankine cycle efficiency be improved ?
>>The Rankine cycle efficiency can be improved by :
- Increasing the average temperature at which heat is supplied .
- Decreasing or reducing the temperature at which heat is rejected.
