The boiler consists of a shell, a tube sheet on each end of the shell, and tubes connecting the two tube sheets. The boiler is mounted above a steel or masonry furnace. The products of combustion leave the furnace and are directed through the tubes at one end of the boiler. After passing through the tubes, the products of combustion exit the
In a watertube boiler, the heating element acts directly on tubes filled with water, which run through the furnace casing, to produce the needed steam or super-hot water. In a firetube boiler, the heating element produces hot water through a more indirect mechanism. The hot flue gases generated by the boiler's combustion are channeled into

Water tube boilers. In the watertube boiler, the water is inside the tubes and gases of combustion go around the outside of the tubes. The advantages of a watertube boiler are a lower unit weight per pound of steam generated, less time required to raise steam pressure, a greater flexibility for responding to load changes, and a greater ability
Why Miura Water Tube Boilers Are More Efficient Than Traditional Fire Tube Boilers. When choosing a steam boiler for your facility, you typically have a choice between a water tube or a fire tube design.While both may have their advantages in certain situations, from an efficiency standpoint, Miura water tube boilers are far more efficient than fire tube boilers.
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or many more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
Damage due to the bursting of water tube is less serious. Therefore, water tube boilers are sometimes called safety boilers. 8. All parts of the water tube boilers are easily accessible for cleaning, inspecting and repairing. 9. The water tube boiler's furnace area can be easily altered to meet the fuel requirements. 29. Demerits : 1.
The main feature of the boiler is that the furnace of the boiler is surrounded by water and therefore there is no requirement of refractory material. It is a single phase pass boiler, which means that the hot gases pass just through the horizontal tube stack before going to the exhaust.
Fin tube boilers represent one of a number of pressurized equipment options used to heat water or convert water into steam under controlled conditions. As in a water tube boiler, water passes through boiler tubes while combustion gases remain in the shell side, passing over the tube surfaces.
The boiler's job is to apply heat to water to create steam. There are two approaches: fire tube and water tube. A fire-tube boiler was more common in the 1800s. It consists of a tank of water perforated with pipes. The hot gases from a coal or wood fire run through the pipes to heat the water in the tank, as shown here:

Thickest materials used in the industry. Boiler shell is 5/16" thick boiler plate 30-40 HP / 3/8" 50-125 HP. Twin boiler tube sheets are 1/2" thick
Since 1958, Cannon Bono Energia is dedicated to the design, manufacturing, installation and maintenance of industrial boilers for standard and special applications.. Fire tube steam generators are the most widespread technology for the heating of all industrial processes which require steam intensively.
Difference between fire tube boiler and water tube boiler Water Tube Boiler. Fire tube Boiler. i) The water circulates inside the tubes which are surrounded by the hot flue gases from the furnace. i) The hot gases from furnace passes through the tubes which are surrounded by water. ii) Externally fired
influenced by boiler design, water chemistry, boiler water oxygen content and boiler operation. Leads to the breakdown of the protective magnetite on the ID surface of the boiler tube. The loss of this protective scale exposes tube to corrosion. The locations of attachments and external weldments,
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.
Consider a fire tube or smoke tube boiler and a water tube boiler with similar evaporation rates the water tube boiler would be compact and relatively light by comparison and its water content would be about 7 tonnes or less compared with the smoke tube or fire tube boiler's 30 tonnes. With double casing radiation loss can be cut to 1 % or less.
Fire tube boiler—a device that passes hot combustion gases through the tubes to heat water on the shell side, p. 298. Igniter—a device (similar to a spark plug) that automatically ignites the flammable air and fuel mixture at the tip of the burner, p. 292. Impeller—a fixed, vaned device that causes the air/fuel mixture to swirl above the
There are two types of steam boilers. One is the fire tube, which is made from one combustion chamber and many tubes. The hot gases that are produced during the combustion process pass from inside the tubes and make a heat transfer with the water that is on the outside of the tubes.

The Fire Tube Boiler is manufactured in Massachusetts with the highest quality materials. The 316L stainless steel fire tube heat exchanger is more resistant to corrosion in comparison to typical copper or aluminum heat exchangers. 316L stainless steel lasts longer and is virtually maintenance free, while also facilitating the transfer of heat more efficiently.
The only reason a boiler can withstand these furnace temperatures is the presence of water in all tubes of the furnace at all times when a fire is present. In a very short period of time, continued firing during a low water condition literally melts steel boiler tubes (Fig. 2).
Fire tube boilers are a lower cost alternative to water tube boilers and are often used for smaller industrial facilities with lower operating pressures. The main advantages of a fire tube boiler are its simple construction, compact size and the ability to easily meet rapid fluctuations in steam demand.
Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as 'fire tube' or 'smoke tube' boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler water.
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low
Fire-tube boilers are generally similar to Scotch marine or locomotive boilers. In this type of boiler, the gases of combustion pass through tubes that are surrounded by water. There are a number of auxiliary boilers of the fire-tube type in use in diesel-driven ships.
