Advantage and disadvantage of liquid fuel over solid fuel

• Handling of liquid fuel is easy and they require less storage space
• Liquid fuels can be fired easily and maximum temperature is attained in time as compared to solid fuels.
• The solid fuels containing higher of moisture burn with great difficulty.
• The solid fuels leave a large quantity of ash after burning and then disposal of ash becomes a problem. Where as the liquid fuels as very little ash after burning. 
• The combustion of liquid fuel is uniform therefor the change in load can be easily met by controlling the flow of fluid.

Disadvantage:

• They are costly as compared to solid fuels
• They require special type of burners
• In cold climate the oil stored in tanks is to be heated in order to avoid the stoppage of flow.

Nuclear Power Plant

Basic Principle:
When nuclear fission happens huge amount of heat is produced. This heat is used to vaporize the water to make steam. Steam flows to turbine and electricity is produced.
Working Principle:
Reactor of a nuclear power plant is similar to the furnace of a steam power plant. The heat is liberated in the reactor due to the nuclear fission of the fuel. The heat is take a up by the coolant circulating through the reactor core. Hot coolant leaves reactor at top and then passes through the tubes of steam generator. Water converts to steam runs the turbo- generator.

Power Plant Energy Sources

A most causal look at our civilization shows the important part played by the supply and control of energy. Many functions necessary to present-day living grind to a halt when the supply of energy stops. While electric power is a common from of energy used in the home today, there are other forms used industrially and domestically Electrical and mechanical energy are manufactured commodities, just like tangible items such as clothing, furniture, or tools. All manufacturing activity processes raw materials as found in nature in to forms more useful for human use. Different type of energy source find different time, some there first sources are wood waste, second time are use Coil, Oil, Natural gas. Other time use Solar, Hydro, Wind occur arc etc. Latest use Nuclear....
