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 is a water tube boiler?
A watertube boiler has pipes (tubes) filled with water which are surrounded and heated by hot gases, whereas a firetube boiler’s pipes (tubes) are filled with fire and heat the water that surrounds them. Overheating will result in the failure of individual small tubes rather than a single massive furnace tube.
What is the difference between fire tube and water 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.
How long do water tube boilers last?
With proper maintenance, they are expected to last at least 15 years or longer.
What are the advantages and disadvantages of water tube boiler?
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. |
Which of the following is an example of water tube boiler?
Water tube boiler: The water circulates inside the tubes which are surrounded by the hot flue gases from the furnace. It generates steam at a higher pressure up to 165 bar. Examples: Babcock and Wilcox boiler, Stirling boiler, La – Mont boiler, Benson boiler, Loeffler boiler etc.
Which is better water tube boiler or fire tube boiler?
Between the two types of boiler designs, water tube boilers are remarkably more efficient than their fire tube counterparts. 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.
