In general, condensing boilers are identified by their internal construction as either fire-tube or water-tube boiler designs, as illustrated in Fig. 2 below. A fire-tube, as the name suggests, has the hot flue gases from the combustion chamber, passing through the tubes and out the boiler vent. These tubes are surrounded by a water jacket.

Mar 22, 2013 · They can be fire-tube Scotch marine with wet- or dry-back design, cast iron, or water tube design. Steam generating boilers require large volumes for the phase change of water to steam to reduce operational issues related to small water to steam interface area. Steam boilers also require proper water chemistry for proper operation.
