When used for the purpose of controlling the temperature of main steam, what is the source of water and steam for the illustrated device? Illustration SG-0013

AI Explanation
The correct answer is C) The source of water is feed water and the source of steam is the superheater outlet.
This is correct because for the purpose of controlling the temperature of main steam, the illustrated device would use feed water as the source of water, which is used to cool the superheated steam from the superheater outlet. The superheater outlet is the source of the steam that needs to be tempered or desuperheated.
The other options are incorrect because they do not accurately identify the sources of water and steam for this application. Option A is incorrect as the desuperheater outlet is not the source of steam. Option B is incorrect as condensate is not the source of water. Option D is incorrect as condensate is not the source of water and the desuperheater outlet is not the source of steam.
