Automatic Tube Cleaning Systems for Condensers and Heat Exchangers

Abstract

The on-line Automatic Tube Cleaning Systems (ATCS) for condensers and heat exchangers provide a positive means for automatic cleaning on a continuous basis, while the exchanger or condenser remains "on stream" and at its full operating potential. Condenser tube fouling contributes up to 50% of the total condenser tube heat transfer resistance. This fouling results in reduced heat exchanger performance, reduced production, increased operational cost, increased back pressure, increased tube failure and increased maintenance. In this paper the two types of on-line cleaning systems, i.e. the Brush and Basket and the Sponge Rubber Ball type for various industrial applications will be discussed. Case studies will be used to demonstrate the actual plant operating and maintenance cost savings from these systems.
