What is Boiler ? | Components & Application | Thermodyne

What is a Boiler? Boiler Definition . Boilers are defined as "Boiler is a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.

Steam Boilers: Classification and Selection | Mechanical

In natural circulation boiler, the circulation of water takes place due to natural convection current and density variation of fluid by the application of heat, i.e., thermo-siphon. This is based on the principle that the density of water is more than steam and as such requires a boiler drum. The method is effective only up to a pressure less

What is Natural Circulation? - Definition from Corrosionpedia

Jan 13, 2015 · Natural circulation is the ability of a fluid in a system to circulate continuously, with the difference in density being the only driving force. In another way, natural circulation is caused by convection currents which result from the uneven heating of the water in a boiler. It may be either free or accelerated, and is primarily used in
