The FMB-HF is a horizontal three-pass fired boiler. Due to the third pass in the convection part the efficiency is the highest possible for marine boilers.
All large and many intermediate-sized boilers are water-tube boiler with a boiler section that consists of closely-spaced water tubes covering the furnace wall. The waterwall boiler design allows much lighter, less expensive walls by having the waterwalls form an integral part of the boiler wall so that the wall is water cooled.
Which type of waterwall is made up of side by side tubes that are touching each other to form a continuous surface: A) tangent tube The use of bent tube boiler designs allows the furnace wall to be lined with tubes, thereby exposing more of the heating surface to:

The horizontal fire-tube boiler is also typical of marine applications, using the Scotch boiler; thus, these boilers are commonly referred to as "scotch-marine" or "marine" type boilers. Vertical boilers have also been built of the multiple fire-tube type, although these are comparatively rare; most vertical boilers were either flued, or with cross water-tubes.
D type Water Tube Boiler Advantages: 1. The D-style boiler is a 100% membrane water-cooled furnace, cost-saving, time-consuming, annual maintenance. 2. It can be customized with superheated steam, all superheaters are placed within the boilers convective zone to optimize performance. 3.
boiler of this type, filled with water and ready for function, can weigh as much as 165 tons, which corresponds to the weight of 120 VW Golfs. Hot water or steam boilers are relatively similar in design (Figure). The boiler pressure vessel is a horizontal, cylindrical tube closed at both sides with an end plate and insulated all around.
boiler horsepower. In addition, with new, enhanced heat transfer tube technology and other boiler design considerations, five or more square feet per horsepower does not necessarily result in higher efficiency. This makes proper boiler efficiency testing even more important when evaluating boiler selection.
