Conditions under which snow will form
Conditions under which snow will form
(OP)
I am exhausting 25000 cfm of air at 100% RH, 50C. This is in a northern climate and the outdoor ambient temperature will be in the vicinity of -40C at times during the winter. Do I need to be concerned about snow formation (and hence a potential maintenance nightmare in clearing it)? What about ice buildup on the discharge?
Any recommendations on how to handle this? Will dehumidifying the air prior to discharge help? Or is this just an added unnessesary expense?
Thanks!

RE: Conditions under which snow will form
Your conditions aren't unlike a large boiler flue gas discharge, and on those types of vertical stacks there is usually some type of de-icing ring system around the flue outlet to keep the icicles at bay. Yeah- you'll get a big plume of steam but it will form small discrete suspended ice crystals before they form "snow".
