COOLING WATER FOULING IN PLATE HEAT EXCHANGERS
Аннотация
Heat exchangers using cooling water are designed with fouling resistance applicable to tubular equipment, in most cases ТЕМРrecommended values. Plant experiences indicate that plate heat exchangers produce substantially lower fouling rates due to turbulence induced by the plate corrugations. Furthermore, plain exchangers are more severely penalized by fouling resistance than tubular exchangers due to the high heat transfer coefficients typical of plate exchangers. To supply reliable fouling data to the designer, APV Company, Limited sponsored a research project to study fouling in plate exchangers with Heat Transfer Research, Inc. (HTRI). The test fluid was a typical, treated cooling tower water. Results of these experiments are described in this paper, showing that at typical operating conditions the fouling resistances for plate exchangers are substantially lower than those used for tubular equipment.
