Question

The steam temperature with increase in load in case of boiler fitted with radiation superheater
1. Increases
2. Decreases
3. Remains Unaffected
4. First increase then decrease

Answer 1

Correct Answer - Option 2 : Decreases

Explanation:

Superheater :

• Heating of the steam further from saturation temperature is called superheating.
• Dry superheated steam is required for proper operation of turbine.
• Work is done in the turbine by superheated steam till condensation begins.
• Superheaters are bundles of tubes located in the path of combustion gases where higher temperature is expected.
• Superheaters are classified as convestion superheaters and radiation superheaters depending upon how they receive heat energy.
• The steam temperature with increase in load in case of boiler fitted with radiation superheater decreases.
