The firetube boiler is usually chosen for low-pressure steam production on vessels requiring steam for auxiliary purposes. Operation is simple and feedwater of medium quality may be employed. The name 'tank boiler is sometimes used for firetube boilers because of their large water capacity. The terms 'smoke tube' and 'donkey boiler are also in use.
Dec 02, 2016 · 4. Vertical Fire Tube Boiler Design. As a one-pass boiler design, vertical fire tube boiler has the furnace on the bottom. The tubes run between the upper and lower tube sheets. With this type of design, the furnace may be comprised of masonry or enclosed on its sides with a water-cooled jacket. Wet-Top & Dry-Top Vertical Tube
heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost.
boiler evaporation system can be found in the literature, especially for water-tube boilers [4-7], but barely for fire-tube boilers. In this work, the modeling of the heat transfer between flue gas and water in a fire-tube boiler is considered. In the literature, a comprehensive modeling for fire-tube boilers has not been treated.
Fire Tube Boilers. Fire tube boilers are the backbone of low pressure steam and hot water applications. The flue gases pass through the furnace and various smoke tubes. Typically, such boilers provide saturated steam or hot water. However, superheated steam supply is possible. With ERK Tubes such boilers can be very compact and low cost.
