A STUDY OF SHIPBOARD UPTAKES AND GAS TAKE-OFFS FOR INERT GAS SYSTEMS (IGS)

An experimental study was conducted using scale models of flue gas uptakes with inert gas take-offs to determine the design and operational conditions that could lead to a deterioration of inert gas oxygen content between the economizer (boiler) and the scrubber in a flue gas inerting system (IGS). Simulated operational conditions were established by a design and operation survey. A comprehensive set of experiments was performed on three models that represent recent uptake designs originally outfitted with IGS and older designs with retrofitted IGS installations. Experimental results are presented for the static pressure distribution in the uptake and take-off, velocity profiles in the uptake, and for the conditions that permit fresh air recirculation in the uptake.
