摘要

The concept of periodic towers is to have sheet metal discs partially submerged in hot,power condensor effluent. As the discs rotate,they absorb heat from the effluent and discharge heat to the air. The tower can be either wet or dry,depending upon the amount of effluent carried into the air side on the surface of the plates. The advantages of the periodic tower lie in the low cost of the discs and the ability to operate dry:it is significantly less expensive than a conventional dry tower with finned tubes. Further,when operated wet,the high capacity losses incurred during warm months by dry towers can be eliminated. The 3main efforts in the periodic tower evaluation are: (1) the design and construction of a full scale model to test and optimize the overall performance, (2) an analysis of ribbing the disc to enhance air side heat transfer rates,and (3) tests on a scale model for preliminary evaluations of flow conditions for the oil,water,and air.
