Steam Boiler Types, Construction and Working Principle

What is a steam boiler? A boiler or a steam boiler in simple words is a device used to generate the steam at a desired pressure and temperature by transferring heat energy which is generally produced by burning fuel in order heat the water to change it to steam. The steam used in the boiler is used for external purposes i.e. electricity generation, heating or other industrial purposes.

Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

Steam Boiler Types Based on Functions, Designs

A boiler utilizing a standard burner with a 4:1 turndown can cycle as frequently as 12 times per hour or 288 times a day because the boiler must begin to cycle at inputs below 25% capacity. With each cycle, pre- and post-purge air flow removes heat from the boiler and sends it out the stack.

Boiler Efficiency and Combustion | Spirax Sarco

The combustion equipment is a component of the steam generator. Since the source of heat is the combustion of a fuel, a working unit must have, whatever, equipment is necessary to receive the fuel and air, proportioned to each other and to the boiler steam demand, mix, ignite, and perform and other special combustion duties, such as distillation of volatile from coal prior to ignition.

External combustion engine - Wikipedia

An external combustion engine (EC engine) is a heat engine where a working fluid, contained internally, is heated by combustion in an external source, through the engine wall or a heat exchanger.The fluid then, by expanding and acting on the mechanism of the engine, produces motion and usable work. The fluid is then dumped (open cycle), or cooled, compressed and reused (closed cycle).
