Which of the devices listed is indicated by arrow "H" shown in the illustration? Illustration SG-0008

AI Explanation
The correct answer is B) Economizer.
The economizer is a heat exchanger that preheats the boiler feedwater before it enters the boiler. This improves the overall efficiency of the steam generation system. The illustration SG-0008 clearly indicates the economizer as the component labeled with the arrow "H", which matches the description of the economizer.
The other answer choices are incorrect because they do not match the component labeled with arrow "H" in the illustration. The overdeck superheater, air heater, and steam soot blowers are different components of the steam generation system, but they are not the component indicated by the arrow "H" in this specific illustration.
