What is the difference between fire tube and water tube boiler?
What is the difference between fire tube and water tube boiler?
The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam.
What is the advantage of water tube boiler in comparison to fire tube boiler?
| Fire Tube Boiler | Water Tube Boiler |
|---|---|
| The overall efficiency of this boiler is up to 75% | The overall efficiency is up to 90% with the economizer |
| Water doesn’t circulate in a definite direction | Water circulates in a well – defined direction |
What are the comparative advantages and disadvantages of fire tube and water tube boilers?
Advantage:
| 1. | Fire tube boiler is in simple design and has a low maintenance cost. |
|---|---|
| 5. | No pure feed water is required in FTB, So cost can be minimized because pure feed water is costly. |
| 6. | For the same power output, the cost of a fire tube boiler is less as compared to a water tube boiler. |
What are the advantages of water tube boiler?
Advantages of water-tube boilers:
- They have a small water content, and therefore respond rapidly to load change and heat input.
- The small diameter tubes and steam drum mean that much higher steam pressures can be tolerated, and up to 160 bar may be used in power stations.
Which boiler is more efficient?
The most efficient boiler models
| Type of boiler | Model | Efficiency rating |
|---|---|---|
| System | Vitodens 100-W | 97% |
| Conventional | Ideal Evomax | 96.20% |
| Oil | Grant VortexBlue Internal | 94.6% |
| Biomass | Grant Spira (& 200kg single hopper and feed auger) | 93.1% |
Which boiler is best for fluctuating demand of steam?

|---|---|
| C. | Babcock and Wilcox boiler is a water tube boiler. |
| D. | all of the above |
What are the disadvantages of water tube boilers?
Disadvantage:
| SL NO | Disadvantage |
|---|---|
| 1. | Complex design and High maintenance cost. |
| 2. | A skilled operator is required for operation. |
| 3. | This is used in large power plants and it is uneconomical for use in small industries. |
| 4. | For the same power output, the cost of a water tube boiler is high. |
What is the disadvantage of fire tube boiler?
Fire Tube Boiler Disadvantages: The fluctuation of load cannot be easily handled. The rate of steam generation is low. A Fire boiler is used in small power plants. The maximum working pressure is up to 20 bar which is a less comparatively water tube boiler.
What is water tube boiler advantages and disadvantages?
Where are water tube boiler used?
Water tube boilers can generate saturated or superheated steam, which is useful for applications such as steam turbine power generation. In addition, these boilers are commonly used in process industries, including chemicals , refining, and pulp and paper manufacturing.
Which type of boiler is best?
Condensing boilers
Pros: Condensing boilers are the best types of boilers for the environment. Condensing boilers allow you to heat your home in a way that’s much more efficient, and that means you’ll save money on your heating bills and save energy as well.
Which boiler is best 2021?
Ideal Logic Plus system boiler
Taking the crown for the best system boiler in 2021 is the Ideal Logic Plus system boiler, retaining its crown from last year. As with the Ideal Logic in the combi range, this boiler comes with an 8-year guarantee, giving you peace of mind for years to come.
Are water tube boilers safer than fire tube boilers?
Most importantly, water-tube boilers are inherently safer in operation than their fire-tube counterparts where a serious problem may result in an explosion of the fire-tubes boiler; while the water-tube boiler may result in a tube leak.
Which kind of water tubes are used for boilers?
The main types are: Screen tubes: Placed before the super-heater, these tubes are adjacent to the furnace and absorb the flame as well as the generated hot gas heat. Superheater tubes: They are placed behind the screen tubes to carry the superheated steam from the boiler Generating tubes: These tubes connect the water drum and the steam drum.
What is a fire tube and water tube boiler?
Pros&Cons of Fire&Water-Tube Steam Boilers
Why is a water tube boiler more efficient?
This stems from a number of factors: Water turns to steam more quickly. When the water flows through the tube, it is surrounded by the heat source, rather than the other way around. Water-tube boilers require less water. Water-tube boilers can adapt to shifting loads more easily. Water-tube boilers tend to last longer.
