Fire tube boiler Is among the easiest forms of boiler plus the design can be earliest pens. It was popular In 18th century. It turned out mainly used for steam locomotive engines. Operation of fire tube boiler Is Its construction. In fire tube boiler, the fuel Is burnt wealth a furnace. The hot gases manufactured In the furnace then passes throughout the fire tubes. The fire tubes are Immersed In water in the mall vessel with the boiler. Because hot gases are passed through these tubes, heat energy in he gases is transferred to the stream surrounds them.
As a result steam is generated within the water and naturally happens and is stored upon the stream within the same vessel of fire tube boiler. This steam is then obtained from your steam outlet for utilizing for required purpose. The stream is fed into your boiler over the feed water inlet. The operation of the fire tube boiler Because steam and water is stored is the same vessel, it really is very difficult to provide high pressure steam from. General maximum capacity of this sort of boiler Is 17. Keg/cam Is actually a capacity of 9 Metric Ton of steam per hour. In a very fire tube boiler, the key boiler vessel is pressurized, therefore this vessel Is burst It will have plausible of major accident due to this explosion. A steam boiler In which hot gaseous products of combustion move across tubes In the middle of boiler water. The river and steam in fire-tube boilers are contained in a large-diameter drum or shell, and the like units often are often called shell-type boilers.
Heat from your products of combustion is transferred to the boiler water by tubes or flues of relatively small diameter (approximately 34 in. Or 7. 5-10 CM) whereby the recent gases flow. The tubes are associated with tube sheets at intervals of end on the cylindrical shell and function as structural reinforcements to guide the flat tube sheets from the force from the internal water and steam pressure. Braces or tension rods are also used In those regions of the tube sheets not penetrated through the tubes.
Fire-tube boilers could be intended for vertical, Inclined, or horizontal positions. The most generally used types Is the horizontal-return-tube (HURT) boiler (see Illustration). Within the HURT boiler, section of the heat In the combustion gases Is transferred straight to the fewer percentage of the shell. The gases and then make coming back move through the horizontal tubes or flues before being passed to the stack. See also Steam-generating unit. Http://www. Corroboratively.
