Question:
_______ increases the steam raising capacity of a boiler.
_______ increases the steam raising capacity of a boiler.
Show Hint
Every \(6 ^\circ\text{C}\) rise in feed water temperature achieved by an economizer saves approximately \(1\%\) of fuel consumption in the boiler.

- Water level indicator
- Economizer
- Pressure guage
- Steam stop valve
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Boiler accessories are auxiliary devices installed in a steam generation system to improve thermal efficiency and increase steam output.
Step 2: Detailed Explanation:
An economizer is a heat exchanger that recovers waste heat from the flue gases leaving the boiler and transfers it to the incoming feed water.
Preheating the feed water reduces the thermal energy required to boil the water inside the drum, which increases the boiler's overall efficiency and steam raising capacity.
A water level indicator and pressure gauge are safety mountings used for monitoring, and the steam stop valve regulates steam flow.
Step 3: Final Answer:
Therefore, an economizer is used to increase the steam raising capacity of a boiler.
