Selection of exhaust fan air volume
Thread Content
Gentlemen, there is a production unit here with an operating pressure of slight negative pressure; the exhaust gas is drawn to the exhaust gas absorption tower by an exhaust fan, and the reactor has an open inlet for continuous feeding. How should the air volume be calculated?
The air volume should include a 10% margin on top of the total exhaust volume, in addition to a 10°C temperature margin. If the device has been in operation for a long time, these coefficients can be increased appropriately

Theoretical calculations provide values for the exhaust volume and leakage amount, but there is also a pipe opening that remains open – should the air flow through that opening be taken into consideration?
Do you mean there’s a gap that stays open, sucking air in?
Yes, it is used for reactive feeding, with belt conveyor feeding
Do you mean the amount of flue gas at the exhaust fan, or the amount of air entering the production unit?
HCL exhaust volume + air volume at the feed inlet (temperature corrected)
