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 — 850oF

MARPOL Annex VI, Appendix IV, mandates that shipboard incinerators must reach a minimum flue gas temperature of 850°C (1562°F) to ensure complete combustion and minimize the release of harmful emissions. This temperature threshold is critical for the thermal destruction of shipboard waste in compliance with international environmental standards.
