Is there a recommended practice about min. tube dia for Heat Exchangers in slurry duty (5% solids w/w) to avoid plugging of tubes?
I've seen velocity recommendations of 2m/s to 4 m/s so I will definitely keep my velocities in that range but is there an independent tube size suggestion too?
Perhaps based on ease of cleaning if plugging occurs? I was considering a 1.25" tube. Comments?
This is a vertical steam heated, titanium tube evaporator for boiling (18 ft tubes). Crystalline inorganic salt is the dissolved component.
