Good day fellows,
I am currently involve in the engineering of an ore processing plant located in a sub-arctic region where the min/max temperature is -20/20C and the mean ambient year round is -1.7C. With chill factor, the ambient drops to -34C (as it was a couple of days back when I check through Blackberry - Viigo Weather).
I'm scared to think that the process plant might freeze to death in this condition! It make sense to me to enclose all equipment and process facilities inside a building. With that the heating can be more controllable, as I thought. However, my initial calculations on the heating requirement using an air change rate of 2-6 at a potential delta temperature of @ 20C, runs to about 6 MW of heat!
That's enormous and it made me asking for hint from the experienced fellows;
Wat really are the considerations for sub-arctic industrial plant ventillation and process heating?
What is the trick to reduce heat loss from forced air change?
My exposures so far are in the Middle East and in the tropical regions where industrial plant heating is not of epic concern.
Thanks in advance.
