Methoden zur Verminderung der Ablagerungsbildung in Wärmeübertragern

Methods for Reducing Deposits in Heat Exchangers. The formation of deposits has long (too long) been considered to be unavoidable and to lie outside the responsibility of the designer. Owing to the enormous operating and investment costs caused by deposit formation and to the development of new processes which are precluded by deposit formation, a number of methods have been developed for reducing or completely preventing the fouling of heat exchangers. The lowest investments are required for chemical fluid processing, which can be retro‐fitted to an existing plant. However, for long term operation with large flow volumes or on use of toxic additives this advantage can shift towards mechanical cleaning processes. Consideration of the reduction of fouling already during the design of a heat exchanger means that it becomes feasible to build much smaller (and hence also lighter) heat exchangers.
