What’s The Working Principle of Steam Boiler

 Boiler or more specifically steam boiler is an essential part of thermal power plant which transfers heat from a fuel source (oil, gas, coal) into steam which is piped to a point where it can be used to run production equipment, to sterilize, provide heat, to steam-clean, etc.

Definition of Boiler

Steam boiler or simply a boiler is basically a closed vessel into which water is heated until the water is converted into steam at required pressure. This is most basic definition of boiler.

Working Principle of Boiler

The basic working principle of boiler is very simple and easy to understand. The boiler is essentially a closed vessel inside which water is stored. Fuel (generally coal) is bunt in a furnace and hot gasses are produced. As the heat passes across the outer portion of the tubes it transfers heat to the water and the water boil. A continuous flow of water is fed through these tubes. Once the water is boiled to steam and a pressure of steam develops. The steam is directed, through piping, to a steam turbine, the steam turns the turbine. Connected to the turbine is an electric generator. As the turbine turns the generator electricity is produced and is directed to the power grid. There are many different types of boiler utilized for different purposes like running a production unit, sanitizing some area, sterilizing equipment, to warm up the surroundings etc.
