In accordance with the international MARPOL Annex VI 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 requires that continuous-fed shipboard incinerators maintain a minimum flue gas outlet temperature of 850°C (1562°F) to ensure complete combustion and minimize the emission of harmful pollutants. This temperature threshold is critical for the effective thermal destruction of waste and compliance with international air emission standards.
