Industrial water tube boilers have a much more efficient design that saves both space and energy. that flows throughout the boiler. With the water tube design, the water is surrounded by heated gases rather than the other way around. The hot gas moves from the firebox into the boiler's main chamber.

Water boiler: Overall efficiency is up to 90%. In the water boiler: The maximum working pressure is 250 bar or you can say 140 kg/cm2.
Read MoreThe boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.

These boilers include a water level indicator; a pressure gauge, steam stop tap security tap, & a manhole like mountings for providing security as well as simplicity of working. The Fuel burns on the grate of the firebox in the boiler and the resultant hot-flue gases are permitted to flow in the region of cross tubes.
Read MoreIn water-tube boilers, the water flows inside the tubes while the hot gas products of combustion heat the tubes from the exterior. By contrast, if the combustion gases flow inside the tubes, thus heating them internally, and the water surrounds the exterior of the tubes, then the boiler is termed a fire tube type. 7. Tubular bank configuration.

Load fluctuation can be easily handed. 5. The rate of steam generation and the quality of steam for suitable power generation are much better.
Read MoreThe fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer a far greater heating surface area for the

Fire tube boilers : Fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal

Working together, the two companies offer streamlined.
Read MoreFig. (2) Shape of fire-tube 2.1.3 Water-tube boilers: • Water-tube boilers have water running through the tubes and fire or gases of combustion surrounding the tubes. The water tubes are connected into a steam drum at the top and a mud drum at the bottom. The fire is in the Combustion chamber. The boiler design can also be

Read MoreTo understand the working principal of Boiler. 2. To demonstrate the different parts of a Boiler. Introduction: The steam-generating boiler's roots go back to the late 1700s and early 1800s with the development of the kettle-type boiler, which simply boiled water into steam. The water was placed above a fire box and then boiled into steam.

In this article, I will explain all the parts of Babcock and Wilcox Boiler along with working, construction, boiler terms, advantages, and disadvantages.
Read MoreTypes of Package Boilers. The D-type Package Boiler. The D-type boiler has a water drum, steam drum, and generating tubes. Water flows into the steam drum, flows down the downcomers and into the water drum. Water is then sent from the water drum through the generating tubes, where the fire is located around causing water molecules to boil off

Read MoreFire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
Read Moreboiler tubes are measured. this leaves very little space for the cold water at the top to work its way down. This confliction of currents slows down the circulation. Scotch boilers cannot be constructed for working pressures much higher than 250 pounds per square inch which prohibits their use with modern turbine plants.
