Construction and Working Principle of Vertical Boiler

Working of Vertical Boiler: When fuel is placed in the furnace and burns then hot flue gas is generated. Then these hot flue gases pass through the fire tube and heat surrounding water. When water becomes heated then it converted in saturated steam. You can call this saturated steam as primary steam.

4 Different Designs of the Fire Tube Boiler: Which Is Best

At these high capacities, not only would the boiler size be an issue, but also the weight would come into effect. Given the increased volumes of water being contained in the fire-tube boilers, there is also an increase in the weight of the unit. Water-tube boilers weigh significantly less than fire-tube boilers at a higher capacity. This should be important to note because if the boiler is to be lifted to higher …

Watertube vs. FireTube Comparison | Gasmaster Industries Ltd.

In a water-tube boiler, it contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn't melt and create problems. When fire tube boilers run low on water, the metal in the boilers shrinks.

Wetback vs Dryback firetube boiler design

The wetback boiler design features a reversal chamber that is jacketed, or completely surrounded by water, which is used to direct flue gasses from the furnace to the tube banks. The surrounding water absorbs burner heat, helping improve operating efficiency as heat from combustion goes directly into evenly heating water instead of refractory.
