Assertion (A): Fire tube boilers have quick response to load changes.R...
Answer:
Assertion (A): Fire tube boilers have quick response to load changes.
Reason (R): Fire tube boilers have large water storage capacity and hence small pressure changes can meet sudden demands.
Explanation:
Fire tube boilers are a type of boiler in which hot gases from the combustion process pass through tubes that are surrounded by water. This design allows for efficient heat transfer and quick response to load changes.
Reason (R) is a correct explanation of Assertion (A) because of the following points:
1. Large water storage capacity: Fire tube boilers have a large water storage capacity due to the presence of numerous tubes that are filled with water. This large water storage capacity allows the boiler to respond quickly to changes in load demand.
2. Quick response to load changes: The large water storage capacity of fire tube boilers enables them to respond quickly to load changes. When there is a sudden increase in demand for steam, the large water storage capacity allows for a small pressure change to meet the sudden demand. This quick response is due to the fact that the water in the tubes absorbs the heat from the hot gases and quickly generates steam.
3. Efficient heat transfer: The design of fire tube boilers allows for efficient heat transfer between the hot gases and the water in the tubes. The hot gases pass through the tubes, transferring their heat to the water, which then generates steam. This efficient heat transfer further contributes to the quick response of fire tube boilers to load changes.
Conclusion:
In conclusion, both Assertion (A) and Reason (R) are individually true, and Reason (R) is the correct explanation of Assertion (A). Fire tube boilers have a large water storage capacity, which allows for quick response to load changes. The efficient heat transfer in fire tube boilers further enhances their ability to respond quickly to sudden demands.
