## Power Plant Engineering

What are the sources of the energy?
>>The major sources of energy are :
• Fuels
• Energy stored in water
• Nuclear energy
• Wind power
• Solar energy
• Tidal power
• Geothermal energy
Write 2 solids and 2 liquids types of fuels.
>>Solid types of fuels are:
• Wood, and
• Coke
>>Liquid type of fuel are
• Petrolium, and
• Gasoline
What are the Gaseous types fuels?
>>Following are gaseous types fuels:
• Natural gas
• Petrolium gas
• Coal gas
• Producer gas
• Blast furnance gas

What is chemical fuel?
>>It is a substance which releases heat energy on combustion. Example-Gasoline and Kersene

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.
