Figure 2.3 Water Tube Boiler: Water tube or "water in tube" boilers in which the conditions are reversed with the water passing through the tubes and the hot gasses passing outside the tubes (see figure 2.3). These boilers can be of single- or multiple-drum type. These boilers can be built to any steam capacities and pressures, and have higher efficiencies than fire tube boilers.

Boiler Information

Boiler system (steam/water) loses water through steam and water leaks. Additional water called "make-up water" is added to the boiler to replace these losses. The amount of make-up water and the level of naturally occurring impurities in water will determine the type of water treatment required.
