Water-Tube Boilers. Water-Tube boiler design is the exact reverse of a fire tube. 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; however their fundamental principles of work are the same. This type of boiler consists of two drums a set of water tubes ...
Operating Principle: A water tube boiler is typically formed of four parts a lower feed water drum sometimes known as a mud drum an upper steam drum with water surface from which the steam is evolved water tubes connecting the two drums together and a super heater / economiser section (depending on the quality of steam required).
It has water and steam. All safety and control devices are mounted on the boiler drum. A bundle of steel tubes: the front end of the boiler drum is connected to the uptake header (water box) by a short tube and the rear end is connected to the down take header (water box) by a long tube. In between the headers a number of small-diameter steel tubes are fitted at an angle of 5° to 15° with the horizontal to promote the water
Jan 24 2019 · Working Principle of Water Tube Boiler . The working principle of water tube boiler is thermal siphoning (circulation of natural water). Basically this type of boiler includes two drums namely steam lower or mud drum. The water tube boiler diagram is shown below and these two drums are associated via two tubes such as downcomer and riser. At first the water is supplied into the steam type drum with the help of a water

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1) it is easy to see that because the tube diameter is significantly smaller much higher pressures can be
