Wetback -vs- Dryback — Heating Help: The Wa

A dry-back example might be an old porkchop style boiler where a refractory chamber and target brick wall is built up the back side. The advantage of a wetback boiler is greater wetted surface area compared to combustion area so more heat from the flue gasses can be absorbed. Another advantage is, depending on internal boiler circulation, a

Figure 3.2.1a shows a dry back boiler where the hot gases are reversed by a refractory lined chamber on the outer plating of the boiler. Figure 3.2.1b shows a more efficient method of reversing the hot gases through a wet back boiler configuration. The reversal chamber is contained entirely within the boiler.
