Which of the following methods is used to supply inert gas from a flue gas system to the cargo tanks?

Correct Answer: Option D — High capacity fan

Flue gas systems utilize high-capacity centrifugal fans to draw inert gas from the boiler uptakes, scrub it, and deliver it to the cargo tanks. These fans provide the necessary pressure and volume to maintain an inert atmosphere, preventing the formation of explosive mixtures within the cargo spaces.
