A5.4 - Clean or not clean - Detecting fouling in heat exchangers

E. Wallhäußer, M.A. Hussein & T. Becker
Fouling describes unwanted deposits on heat transferring surfaces leading to reduced heat transfer and increased heat transfer resistance. Hence, fouling is a severe issue particularly in food processing because product quality and safety cannot be ensured, and plant efficiency is reduced. As a result, cleaning is performed which limits processing time and increases plant downtime as well as costs because usually it cannot be adapted to amount and type of fouling present. Monitoring of cleaning...
