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.

Good topic. Can you share some case studies and success stories?
Thanks for your comments.
Unfortunately the information can not be disclosed. Hope you understand.
