2021/8/19 · In fire tube boiler the hot gases from the furnace flows through pipes and water flows outside the tube. 2. Water tube boilers are light in weights. Fire tube boilers are heavy in weight. 3. It is also called externally fire tube boiler. It is called internally fired tube boilers. 4.
The water-tube boiler is those boiler in which the water is present inside the tubes and fire or hot gases surround these fire tubes. The examples of water tube boilers are a La-Mont, Benson, Stirling, Babcock and Wilcox, Yarrow and Loeffler boiler.
The main difference between Fire Tube and Water Tube Boiler is that In Fire Tube Boiler, hot flue gases pass through tubes and water surrounds them, and In Water, Tube Boiler water passes through tubes and hot flue gasses is surround them. These boilers mostly use in the power development industries, sugar industries, cotton industries, etc.
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.
Fire Tube Boiler It is a boiler in which the hot flue gases is present inside the tubes and the water surrounds these tubes. As fire is present insides the tubes, hence it is called as fire tube boiler. The steam produced by these boilers have pressure of about 25 bar
ZBG fire tube boilers include WNS oil and gas fired boiler and DZL packaged boiler, capacity 1 ton/hr ~20ton/hr. ZBG water tube boilers include SZS oil and gas boiler, SZL biomass boiler, CFB boiler, waste heat boiler and so on, capacity 6 ton/hr ~400ton/hr.
These design changes have resulted in a marked improvement in heat transfer efficiency of the fire-tube boilers. Another outcome from this is that the overall footprint (boiler size) of the fire-tube boilers will be smaller in comparison to the water-tube boilers only in the lower capacities up to about 4,000,000 BTU/hr.
WATER-TUBE AND FIRE-TUBE BOILERS. An Account of the Experiments made by Chief Engineers Loring and Baker, 1L S. Navy, on a Horizontal .Fire-Tube and a Vertical Water-Tube Boiler, at the Washington Navy Yard, to ascertain their relative Economic Vaporizations with different kinds of Coal. By Chief Engineer ISHERWOOD, V. S. Navy.
A fire-tube boiler is a boiler in which fire tubes are immersed in water, and the hot flue gases produced by the combustion chamber flow inside the fire tubes. The hot flue gases transfer their heat to the outside water through the conduction process. When heat transfers to the water, it converts into steam.
Fire tubes are large and not easy for transporting whereas, in a water tube boiler, it is not an issue. The size of the drum in fire tube boiler is large as well as injury caused by burst is also large whereas in water tube if any water tube gets damage then we can replace it easily. The efficiency of fire tubers are up t0 75% whereas in water
Water and fire tube boilers - SlideShare Apr 17, 2015 · Water Tube Boilers In this type of boiler water passes through the tubes while the gases remain in the shell side, passing over the tube surfaces • Used for high steam demand and pressure requirements • Capacity range of 4,000 – 120,000 kg/hour • Combustion efficiency enhanced by …
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. This is because of condensed tangential pressure on tubes which is known as hoop stress.
2021/3/2 · Single tube steam boilers have only one fire tube or water tube. Simple vertical boiler and Cornish boilers are single tube boilers. #10 Multi Tubular Boilers In a multi-tubular steam boiler, there are two or more fire tubes or water tubes. #11 Stationary Boilers
The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers.
2020/8/12 · Hydronic Boiler Comparison: Fire-tube Boilers vs. Water-tube Boilers. A Look at Efficiency and Fire-tube Boiler Minimum Flow Rates. With the constant rise in equipment costs, building owners and engineers are constantly looking for ways to decrease initial and utility costs for their HVAC projects. This has driven the market standard to pumps
2020/7/20 · 1.Water converts into steam very Quickly.When the water flow through the tubes,it is only surrounded by heat rather than the other way around. Since the tube holds less water than the tank of fire tube boiler so,it takes less time to convert that water into steam and thus less consumption of fuel.
2019/11/22 · 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.
Fire-tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Fire-tube boilers, typically have a lower initial cost, are more fuel-efficient, and are easier to operate. Their capacities are up to 25tons/hr and 17.5 kg/ cm2.
2018/6/5 · S.No. Fire tube boiler. Water tube boiler. 1. In Fire-tube boilers hot flue gases pass through tubes and water surrounds them. In Water-tube boilers water passes through tubes and hot flue gasses surround them. 2. These are operated at low pressures up to 20 bar. The working pressure is high enough, up to 250 bar in super critical boilers.

2016/3/19 · Difference between Fire Tube Boiler and Water Tube Boiler: 1. Hot flue gases flow inside the tube and the water outside the tube. Water flows inside the tube and the flue gases outside the tube. 2. This boiler pressure is limited up to 20 bar. These boilers are generally low or medium pressure boiler.
Hydronic Boiler Comparison: Fire-tube Boilers vs. Water
Water tube boiler occupies a less floor area when compared to a fire-tube boiler that requires a large floor area. Water-tube boilers are lighter in weight and therefore transportation is also not tedious. Fire tube boilers on the contrary are heavy in weight and therefore they cause a lot of challenges to transport.
