logical 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.

A drying process and its apparatus utilizing a refrigeration cycle. The drying apparatus is constructed to interpose a heat exchanger between an evaporator and a heater so that air in a drying chamber may be dried and heated in a cycle of introducing hot air in the drying chamber into the heat exchanger to pre-cool hot air, guiding precooled air to the evaporator to dry it due to dehumidification by cooling, introducing cooled and dried air into the heat exchanger again to increase the temperature, introducing the air to the heater to further heat it and returning dried and heated air to the interior of the drying chamber.
4532721 TEXTILE DRYER HEAT RECOVERY SYSTEM
A cooler made of aluminum for use in Stirling engines comprises a multiplicity of cooling tubes, a pair of headers joined to opposite ends of the cooling tubes, inner fins provided in the interior of the cooling tubes, a multiplicity of plate fins intersecting and attached to the group of cooling tubes, and a shell surrounding the cooling tubes and the plate fins. The shell is joined to the headers and has an inlet and an outlet for cooling water.
