will a sloped 8" pipe freeze?
(OP)
Hello all,
As you can see I'm not a civil, but I've been tasked with designing a drain system for a coal power plant. My issue is, do I need to heat trace the drain line for winter use? Here's some points about the drain:
- 8" diameter carbon or stainless steel pipe; still haven't decided on material
- 20-30 degree slope down a coal conveyor belt enclosure
- About 700 feet long
- Will be a coal dust and water slurry; not sure of the coal dust to water ratio
- Belt enclosure is not heated
- We get down to the single digits or negatives (in Farenheight) for several days at a time, and stay below freezing for weeks in the winter
- Will use the system once a day; approx. 200 gallons over two hours each use
I can't tell if the slurry will build a small layer of ice each use until it clogs and bursts without heat trace, or if it will be ok. Any thoughts are welcome and thank you in advance!

Yes you need to trace it.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way
