BRegenerative air heater
CIntegral or interdeck superheater
DRetractable soot blower
AI Explanation
The correct answer is C) Integral or interdeck superheater. The illustration SG-0008 shows a boiler cross-section, and an integral or interdeck superheater is the device depicted. This type of superheater is incorporated directly into the boiler design, as opposed to a separately fired superheater (option A) which is a standalone component. The illustration does not show a regenerative air heater (option B) or a retractable soot blower (option D), which are different boiler components not featured in this particular diagram.
