HEAT EXCHANGER DESIGN FOR FOULING SERVICES
摘要
The procedure by which fouling is generally
included in heat exchanger design originated over
forty years ago. It is based on guessing a time-independent
oversurfacing factor without identifying
the characteristics of fluids or exchangers
which promote fouling. As a result, very little
has been learned about fouling and its suppression
through rational exchanger design.
In the present paper a time-dependent procedure
is developed using classical fluid dynamics
and heat-exchanger design variables. With
only fragmentary information at hand it is possible
to generate fouling equations for various streams
under different operating conditions.
