MARINE FOULING OF TITANIUM HEAT EXCHANGERS

A series of marine fouling experiments were conducted at Freeport, Texas, on two single-pass titanium heat exchangers. The exchangers, which were constructed with commercially pure titanium tubes (5/8-inch (1.59- centimeter)) outside diameter by 30-inch (76.3-centimeter length) and 6Al-4V alloy tube sheets and headers, were operated on natural seawater. One of the exchangers was fed electrolytically chlorinated seawater while the other was run with untreated seawater feed. Velocity and chlorination levels were varied to determine the effect of these two variables on fouling of the titanium surfaces. Operating conditions similar to those that might be expected in shipboard heat exchanger/condenser usage were modeled.
