Design of Boilers (With Diagram) | Thermodynamics

In a water-tube boiler, the water is in the tubes while the fire is external to the tubes. The hot flue gases pass around and between the tubes, heating the water and then out the boiler vent. Figure 2: (a) Water-tube boiler arrangement (Not typical of any manufacturer's product – for illustration purposes only) and (b) simplified fire-tube

Firetube vs. Watertube Comparison - Johnston Boiler

pass boiler. Refractory back and water back boilers (see 480' BURNER BOILER 2ND Figure 7 Figures 8 through 1 1) differ in their construction at the first turn for the hot combustion flue gas products. Refractory back boilers have only a single rear tube sheet that must work with the vastly different temperatures in a firetube boiler.

Water-tube or fire-tube condensing - Hot Water Boilers

The water-tube boiler may just result in a tube leak, which can be easily contained. Conclusion. Water-tube and fire-tube boilers are complete opposites in terms of the location of the water relative to the hot gases resulting in water-tubes boilers being inherently more efficient in terms of the heat transfer.

fire tube wet back steam hot water boiler - Zozen Boiler

Fire-tube boiler - Wikipedia. The hot gases are directed along a series of fire tubes, or flues, that penetrate the boiler and heat the water thereby generating saturated ("wet") steam. The steam rises to the highest point of the boiler, the steam dome, where it is collected. The dome is the site of the regulator that controls the exit of steam
