Water Tube Steam Boiler Design

However their fundamental principles of work are the same.

Water tube steam boiler design.

Water tube boilers may differ in design. 100 to 550 psig on steam available to less than 9 ppm nox the cbcw is the newest member of the cleaver brooks industrial watertube boiler family. Fuel is burned inside the furnace creating hot gas which heats water in the steam generating tubes. The cleaver brooks nebraska d style industrial watertube boiler provides up to 1 050 f superheated steam in the lower maintenance d configuration.

With this type of design the furnace may be comprised of masonry or enclosed on its sides with a water cooled jacket. Water tube boiler design is the exact reverse of a fire tube. The internal structure of this boiler includes a tiny steam drum small width tubes. With the water tube design the water is surrounded by heated gases rather than the other way around.

The components of this boiler generate high volume vapor for high capacity applications. Advantages of water tube boiler. 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. The water tube boilers are mainly used for generating steam with high temperature as well as pressure.

Here the water is inside the pipes and the combustion gases move around the outside of the pipes. The hot gas moves from the firebox into the boiler s main chamber. Design with a 100 membrane water cooled furnace this boiler system includes high efficiency boiler and burner heat recovery economizer and advanced control system. In a typical water tube boiler design as shown in the figure it consists of two drums the steam drum and the water or mud drum.

This is the basic definition of water tube boiler. The tubes run between the upper and lower tube sheets. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water. As a one pass boiler design vertical fire tube boiler has the furnace on the bottom.

Wet top dry top vertical tube. A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. That flows throughout the boiler. The rear header was connected to a horizontal box header which was also attached to the steam drum.
