Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun's core and fuse to create a helium atom. stars that are about the size of our sun, and provides them with continuous energy and heat.

Electricity is a form of energy. Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons.

Electricity is both a basic part of nature and one of the most widely used forms of energy. The electricity that we use is a secondary energy source because it is produced by converting primary sources of energy such as coal, natural gas, nuclear energy, solar energy, and wind energy into electrical power.

Not all the heat energy released through the combustion process is used to heat the water and steam in the boiler tubes. To efficiently use the heat energy produced, the exhaust flue gases are used to preheat the water and air entering the boiler. Induced draught fans are used to extract the flue gases (exhaust gases) from the boiler.
