Water Tube Steam Boiler Design

Multi pass boilers are an extremely common option.

Water tube steam boiler design. Industrial water tube boilers have a much more efficient design that saves both space and energy. This is the basic definition of water tube boiler. Water tube boiler design and working. The water is boiled and steam is generated in the upper drum.

The hot gas moves from the firebox into the boiler s main chamber. 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. With the water tube design the water is surrounded by heated gases rather than the other way around. Water tube boilers may differ in design.

Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water. There are many advantages of water tube boiler due to which. At first the water is supplied into the steam type drum with the help of a water pump. A fire tube boiler is a type of boiler in which hot gases pass from a fire through one or many more tubes running through a sealed container of water.

The heat of the gases is transferred through the walls of the tubes by thermal conduction heating the water and ultimately creating steam. These boilers are typically found in colleges universities or areas where the system is used to produce steam for space heating or use to create hot water. Innovative water tube design. The fire tube boiler developed as the third of the four major historical types of boilers.

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 scotch fire tube boiler design is most commonly referred to as the scotch marine boiler. These pipes are attached to a steam drum and a mud drum. Scotch fire tube boiler design.

The front and rear walls are welded and refractory free as well as the burner throat when integrated with our natcom burner. However their fundamental principles of work are the same. On this design straight tubes were rolled into mud drum and the front headers were connected to the steam drum. This type of boiler consists of two drums a set of water tubes a feedwater channel line and a combustion gas vent stack.

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 water tube boiler diagram is shown below and these two drums are associated via two tubes such as downcomer and riser. The d style is a 100 membrane water cooled furnace reducing costly time consuming annual maintenance.

D style boilers can be customized to provide superheated steam.
