Boiler: A Boiler is a closed vessel in which steams are generated (Water to steam) with the help of coal-burning or other fuel substances.. Basically, There are two types of Boiler. Fire Tube Boiler; Water Tube Boiler; Fire Tube Boiler: The fire-tube boiler is the boiler in which fire (hot flue gases) is inside the tube and water is surrounded by them.. Some example of Fire Tube Boiler are:
Construction: A horizontal steam and water drum: this is the main part of the boiler.It is supported by a steel structure at a certain height and is independent of brickworks. The size of the boiler drum is small as compared with the boiler drum of a fire-tube boiler of the same capacity.
The Scotch Marine Boiler is a firetube boiler, in that hot flue gases pass through tubes set within a tank of water. 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 is a large number of small-diameter fire-tubes.
fire-tube boiler[′fīr ‚tüb ‚bȯil·ər] (mechanical engineering) A steam boiler in which hot gaseous products of combustion pass through tubes surrounded by boiler water. Fire-tube Boiler a cylindrical steam boiler with fire tubes extending inside the water area of the boiler from one end plate to the other. A fire-tube boiler may have one or
In a fire tube boiler, hot gas passes through the pipes and boiler feed water is inside the shell to be converted into steam. Fire tube boilers are usually used for relatively small steam capacities with low to moderate steam pressures. As a guideline, competitive fire tube boilers for steam speeds up to 12,000 kg / hour with pressures up to 18
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.
A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.. Advantages of Water Tube Boiler. There are many advantages of water tube boiler due to which
Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5kg/cm2. Water Tube Boiler: Water tube or "water in tube" boilers in which the conditions are reversed with the water passing through the tubes and the hot

Some of the larger, older scotch boilers would have two or even three different
Water Tube Boiler Design . Whats the difference in application and why use one type over the other? Water tubes are generally considered safer. They contain much less water than fire tubes, so if a disturbance occurs (tube breaks, boiler melt down) there isn't as much water/steam to have the potential to escape the boiler.
WNS SERIES FIRE TUBE BOILERS. WNS series gas-fired (oil-fired) boilers are wetback fire tube boilers with a two-pass or three-pass design. Threaded flue tubes are used for heat transfer and condensator & economizer are added to decrease the exhaust gas temperature to 60℃, which manage to achieve a thermal efficiency up to 98%.
The design of water tube boilers is strictly opposite to that of fire tube boilers design. In water tube boiler systems, the water to be heated is enclosed inside the boiler tubes whereas the hot combustion gases exhausted by the burner keep circulating around the tube surfaces.Operating Principle: Natural water circulation..

Introduction Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from 250 to 50 000 kg/h (175 to 34 000 kW). Operating Principle Steam is generated by heating a large volume of water in a pressurised drum by means of hot gases, which are produced from the combustion of liquid or
Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers.
Steam outputs from 10,000 kg/h to 30,000 kg/h BWR Fire Tube Boilers feature three pass design and include a tubular construction flue gas reversal chamber. This proven feature, unique to Babcock Wanson, enhances water circulation thereby greatly reducing the risk of internal fouling (sludge accumulation in the bottom of the boiler).
Fire Tube boiler is the simplest form of the internal furnace, vertical fire tube boiler.Fire tube boilers are a portable boiler and it requires a small floor space. The steam rating in fire tube boilers doesn't exceed 2500 kg per hour and pressure is limited to 10 bars.

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 scotch fire tube boiler design is most commonly referred to as the scotch marine boiler. With this design, the furnace is a big diameter tube located inside of the boiler. The furnace and boiler are circumferenced by water. Some of the larger, older scotch boilers would have two or even three different boilers. However, most of today's
tube boiler was not prevalent until after the first water-tube boiler design patent of 1867; thus, the term Boiler Horsepower (Bhp) has been associated with fire-tube boilers from the earliest days of boiler development). During this period, variations in steam engine efficiency made it difficult to assign a qualified rating (i.e. Pounds per

The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers.
IMPROVEMENTS IN BOILER MAINTENANCE . The ease of cleaning and maintenance of condensing boilers varies based on the type of technology and material design. Stainless steel condensing boilers feature either a water tube or fire tube heat exchanger.
A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved.
The fire tube single shell, single pass boiler is a simple, low cost solution for sub-critical waste heat boiler applications. Used when boiler steam quality is not a primary concern Design allows for small vapor space (limiting flexibility for handling rapid process condition changes)
Fire-tube boiler: This is a boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes.; Since fire is inside the tubes and hence it is named as fire tube boiler.The heat from the hot gases is conducted through the walls of the tube to the water.
