Abstract:

This report summarizes the results of a two year project led by the Naval Facilities Engineering and ExpeditionaryWarfare Center to demonstrate the potential for the patented I2 infusion system to reduce the rate of foul within Department of Defense shipboard heat exchangers. Fouling of DoD shipboard heat exchangers is a chronic and costly operating problem that requires significant maintenance. The heat transfer performance and efficiency decreases due to the fouling of the heat exchanger plates and tubes resulting in additional fuel consumption and increased greenhouse gases. Costly and labor consuming, remedial chemical cleaning protocols currently used produce considerable hazardous waste. Through the infusion of air containing elemental iodine vapor into the heat exchanger, this demonstration has shown that the formation of biological foul has been reduced and the period between physical cleanings extended while maintaining acceptable system parameters.
