Question 1052 Deck General

The correct answer is C) High capacity fan. In a flue gas system used to supply inert gas to cargo tanks, a high capacity fan is employed to draw the inert gas from the stack and deliver it to the cargo tanks. This fan provides the necessary pressure and flow rate to effectively displace the cargo vapors and maintain an inert atmosphere in the tanks. The other options are incorrect - exhaust gas pressure from the stack (A) is not sufficient to provide the required flow, an inert gas compressor (B) is not typically used in this application, and natural aspiration (D) does not generate enough pressure to deliver the inert gas to the cargo tanks.
