The primary function of a "flue gas type" inert gas system is to _________.

Correct Answer: Option A — supply conditioned gas with reduced oxygen content

Flue gas systems utilize boiler exhaust, which is scrubbed and cooled to remove soot and sulfur oxides. The primary objective is to supply a large volume of gas with an oxygen content below 8% to inert cargo tanks, ensuring the atmosphere remains non-flammable throughout the cargo discharge and ballasting process.
