Steam drum covers are located at the top of a water-tube boiler, the steam drum is where dry, pure steam collects and is drawn off while the remaining water is passed back to the heat source. Problems with the steam drum causes, at the least, inefficient heat distribution and can also result in corrosion of the steam system or boiler malfunction.

Sep 18, 2020 · The back of the boiler is constructed with a refractory lined door (dry back) or water filled (wet back). The wet back boiler is more difficult to construct and requires extra seals, so it is more expensive, but the increased heat transfer area improves efficiency. Fire-tube boilers …
Gas(oil) Fired Split Steam Boiler. This series of boilers is designed with a classic shell type, full-wet back, down-flow and three-pass design structure. The fuel is fully burned in the large-capacity combustion chamber, and the combustion heat load is low, which can greatly reduce the emission of harmful substances such as CO and NOx.
Why Our Boilers Are Designed As Wet-Back Boilers: Dry-Back Boiler VS Wet-Back …
A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. Sectional diagram of a "wet back" boiler. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes.
A further subclassification of scotch boilers describes the end closure opposite the burner end of the boiler. A wet-back means the end closure is water cooled and a dry-back means the end closure is not water cooled and relies on fire brick, refractory, or a combination of both …

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.
Conventional Oil Boilers vs. Energy Kinetics Oil Boilers. As seen in this thermal image, heavy cast iron boilers finish hot at 160°F to 200°F—even in the summer—causing up to 40% annual energy losses. Energy Kinetics boilers have over 90 lbs. of insulation and jacketing, virtually eliminating all losses. Common boiler controls and outdoor

High Efficiency Residential Oil Boilers | Energy Kinetics
This design has evolved as materials and manufacturing technology has advanced: thinner metal tubes were introduced allowing more tubes to be accommodated, the heat transfer rates to be improved, and the boilers themselves to become more compact. Typical heat transfer data for a three-pass, wet back, economic boiler is shown in Table 3.2.3.
Hot water heating systems (Figure below) transport heat by circulating heated water to a designated area. Heat is released from the water as it flows through the heating unit (coil, terminal). After heat is released, the water returns to the boiler to be reheated and recirculated. Low temperature hot water boilers are ≤ 250°F.
The wet back boiler design uses separate tube sheets between tube passes which can be more forgiving with load changes. Wetback firetube boilers offer a more optimal functional footprint, with lift off or split-hinged doors that require no cool-down period and can be opened immediately. While there is no expensive refractory to maintain
