Abstract
Herein is described a method for feeding chlorine to a heat exchanger (condenser) for biological fouling control by targeting the feed to only a few tubes at a time. The assembly comprises a manifold surrounded by a seal which directly contacts the condenser tube sheet, thereby feeding chlorine to only a few selected condenser tubes at a time and the seal serves to restrict the flow of water through the tubes, thereby increasing the contact time between the chlorinated water and the fouling mass in the tubes. The manifold, powered by a pneumatic/hydraulic drive, moves across the entire condenser tube sheet so that all tubes are chlorinated for the same duration. A principal advantage of this system is that it allows the feed of relatively high concentrations of chlorine to the selected tubes, but is designed to meet EPA effluent limitations without dechlorination.
