Water Tube Steam Boiler Design

The tubes run between the upper and lower tube sheets.

Water tube steam boiler design. 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. Design with a 100 membrane water cooled furnace this boiler system includes high efficiency boiler and burner heat recovery economizer and advanced control system. The water tube boilers are mainly used for generating steam with high temperature as well as pressure. This is the basic definition of water tube boiler.

That flows throughout the boiler. The components of this boiler generate high volume vapor for high capacity applications. On this design straight tubes were rolled into mud drum and the front headers were connected to the steam drum. Wet top dry top vertical tube.

As a one pass boiler design vertical fire tube boiler has the furnace on the bottom. A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. 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. The rear header was connected to a horizontal box header which was also attached to the steam drum.

The internal structure of this boiler includes a tiny steam drum small width tubes. The cleaver brooks nebraska d style industrial watertube boiler provides up to 1 050 f superheated steam in the lower maintenance d configuration. Water tube boiler design is the exact reverse of a fire tube. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.

Innovative water tube design industrial water tube boilers have a much more efficient design that saves both space and energy. Here the water is inside the pipes and the combustion gases move around the outside of the pipes. Water tube boilers may differ in design. With this type of design the furnace may be comprised of masonry or enclosed on its sides with a water cooled jacket.

With the water tube design the water is surrounded by heated gases rather than the other way around. However their fundamental principles of work are the same. The hot gas moves from the firebox into the boiler s main chamber. Fuel is burned inside the furnace creating hot gas which heats water in the steam generating tubes.
