In accordance with the international MARPOL AnnexVI regulations, what is the minimum allowable flue gas outlet temperature for a continuous-fed shipboard incinerator while in operation?

Correct Answer: Option C — 850F

MARPOL Annex VI requires that continuous-fed shipboard incinerators maintain a minimum flue gas temperature of 850°C (1562°F) to ensure complete combustion and minimize harmful emissions. Note that the provided option 850F is a common distractor; the regulatory standard is 850°C, which is equivalent to approximately 1562°F.
