Water Tube Steam Boiler Design

As a one pass boiler design vertical fire tube boiler has the furnace on the bottom.

Water tube steam boiler design.

Water tube boiler design is the exact reverse of a fire tube. Advantages of water tube boiler. However their fundamental principles of work are the same. Fuel is burned inside the furnace creating hot gas which heats water in the steam generating tubes.

With this type of design the furnace may be comprised of masonry or enclosed on its sides with a water cooled jacket. A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. The internal structure of this boiler includes a tiny steam drum small width tubes. This is the basic definition of water tube boiler.

Here the water is inside the pipes and the combustion gases move around the outside of the pipes. Innovative water tube design industrial water tube boilers have a much more efficient design that saves both space and energy. The rear header was connected to a horizontal box header which was also attached to the steam drum. 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.

Design with a 100 membrane water cooled furnace this boiler system includes high efficiency boiler and burner heat recovery economizer and advanced control system. 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. That flows throughout the boiler. With the water tube design the water is surrounded by heated gases rather than the other way around.

On this design straight tubes were rolled into mud drum and the front headers were connected to the steam drum. Water tube boilers may differ in design. The hot gas moves from the firebox into the boiler s main chamber. The tubes run between the upper and lower tube sheets.

Wet top dry top vertical tube. The cleaver brooks nebraska d style industrial watertube boiler provides up to 1 050 f superheated steam in the lower maintenance d configuration. The components of this boiler generate high volume vapor for high capacity applications. The water tube boilers are mainly used for generating steam with high temperature as well as pressure.
