Question 95Steam Plants - QMED
70% to passIn a single furnace boiler, where is the steam typically cooled for use as auxiliary steam?
ACondenser
BDesuperheater
CSuperheater
DAir ejector
AI Explanation
The correct answer is B) Desuperheater. In a single furnace boiler system, the steam is typically cooled for use as auxiliary steam in the desuperheater. The desuperheater reduces the temperature of the superheated steam to the desired temperature before it is used for auxiliary purposes, such as heating or process applications. This ensures the steam is at the appropriate temperature and pressure for its intended use. The other answer choices are incorrect because: A) Condenser is used to condense steam into water, not cool auxiliary steam; C) Superheater further heats the steam, and D) Air ejector is used to remove air from the system, not cool the steam.
