Plate Heat Exchanger having narrow channel most probably "not recommended" for fluid contains solid and/or slurry services. However, there are still many success story of using PHE in abovementioned services.



There are some rule-of-thumbs to gage if a plate heat exchanger suitable for fluid contains solid or slurry :

i) 80% of the particles are less than 70% of the interplate gap on the heat exchanger.

ii) 100% of the particles are less than 90% of the interplate gap

iii) Flowing velocity is below erosional velocity (causes premature plate failure)

iv) The minimum wall temperature is above a point where crystal growth is expected.
