The most common type of boiler system especially for industrial uses, fire tube boilers, has been around for a long time because of their ability to meet steam needs when the demand is large and constant. These pressure vessels are filled with water, and the fuel used to heat the water is kept inside a series of tubes.
Which type of steam boiler is the best?
Condensing boilers can be the most efficient type of boiler, often achieving a fuel-to-steam efficiency rate of up to 99 percent.
Which boiler is used in steam engine?
Fire-tube boilers were the main type used for early high-pressure steam (typical steam locomotive practice), but they were to a large extent displaced by more economical water tube boilers in the late 19th century for marine propulsion and large stationary applications.
What is boiler in steam power plant?
A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries. The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. The generator then converts the mechanical energy into electric power.
What is the most common boiler type?
Fire tube boilers are the most common type of boiler. The burning fuel passes through a series of tubes composed of a mild steel material, located within the water tank. As the fuel is pumped through the tubes, heat is transferred to the water, ultimately producing steam. Most modern boilers run on natural gas.
What is boiler types of boiler?
There are mainly two types of boiler – water tube boiler and fire tube boiler. In fire tube boiler, there are numbers of tubes through which hot gases are passed and water surrounds these tubes. In water tube boiler the water is heated inside tubes and hot gasses surround these tubes. …
