30/8/2019 · Fire Tube Boiler In Fire Tube Boilers, hot flue gases will be flown inside the tube and these tubes are surrounded by water. These are the low-pressure boiler which cannot generate much heat compared to water tube boilers. As the production of heat is less the
Water tube boilers can be 90% efficient, as compared to a 75% limit for fire tube designs. The design of water tube boilers is generally more complex than for fire tube boilers, and maintenance is typically greater. Expertise is required for efficient water tube boiler
Difference Between Water Tube Boiler And Fire Tube Boiler
9/1/2019 · Fire Tube Boiler: 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
Within water tube boiler, expanded areas could be employed to create it stream-lined if the gas flow is thoroughly clean. The pressure drop of flue gas may also be decrease when compared with an equal fire tube boiler due to design intensiveness. Water tube boiler
Steam in water tube boiler as compared to fire tube boiler a) Can be raised rapidly b) Is raised at slower rate c) Is raised at same rate d) Could be raised at fast/slow rate depending on design In a uniflow engine A. Steam enters and exhausts through the same port
19/3/2016 · So these boilers are generally high pressure boiler. 3. Fire tube boiler have lower rate of steam production compare to water tube. It has higher rate of steam production. 4. These boilers are almost internally fired. Furnace is placed at the one end of fire tube. These boiler…
19/3/2016 · The boiler is divided into two main types. One is known as fire tube boiler and the other one is known as water tube boiler. These boilers is largely used in power development and other industrial like sugar industries, cotton industries etc. for steam generation.
Difference between Fire Tube Boiler and Water Tube Boiler - mech4study
Question is ⇒ Steam in water tube boiler as compared to fire tube boiler, Options are ⇒ (A) can be raised rapidly, (B) is raised at slower rate, (C) is raised at same rate, (D) could be raised at fast/slow rate depending on design, (E) none of the above is true., Leave
5/6/2018 · Comparison between Fire Tube and Water Tube Boiler can be done in 14 aspects. Those aspects are operating pressure, passage of material type in tubes, rate of steam generation, handling of load fluctuation, floor area requirement, efficiency, operator skills, design, maintenance cost are listed below in the tabular form.
The efficiency of the fire tube boiler is less as compared to the water tube boiler. The efficiency of the water tube boiler is more. The maintenance of this boiler is costly. It requires regular inspection. They are easy to maintain as they are externally fired. . Ex: .
23/4/2016 · 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 and that's why they fall under the category of low pressure boilers.
13/6/2013 · From a cold start, the firetube boiler, due to its larger water volume, takes longer to bring up to operating temperature or pressure vs. a similar sized watertube boiler. With less water volume, a watertube boiler can follow load swings more precisely and generally has better turndown.
20/7/2020 · As the volume of area of production of steam is less in water tube boiler the water tube boilers are able to produce high pressure steam and at a faster rate than the fire tube boiler. They can also produce super heated or saturated steam according to the …
28/5/2020 · All parts of the water tube boiler are easily accessible for cleaning, inspecting and repairing compared to fire tube boiler. The water tube boiler's furnace area can be easily altered to meet the fuel requirements. Demerits of Water Tube Boiler over Fire Tube Boiler
2/7/2019 · A water tube boiler produces steam in as little as five minutes, compared to an hour or more for fire tube boilers. As a result, fuel savings costs can be significant over time. Water-tube boilers require less water.
Apr 23, 2016 · The difference between fire tube boiler and water tube boiler can be done on various points. These points include types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boilers is very crucial.
The movement of water is much faster than the fire tube boiler because of conventional flow, hence the rate of heat transfer is high which results in higher efficiency. Water boiler: Overall efficiency is up to 90%. In the water boiler: The maximum working pressure is 250 bar or you can say 140 kg/cm2.
