re leakage measurement

Dear Sir, 

To find out the false air across the mill, we need to carry gas analysis,i.e. Oxygen analysis at Mill inlet, at Mill outlet and at Mill fan inlet after Baghouse or ESP.

Based on the oxygen content at these locations you can find out amount of false air across the mill circuit.

Generally flase air is through the Rotary feeder at mill inlet, Mill body, mill door, tie rod seiling is a major false air source..

Formula is (O2 mesured at  point 2-O2 measured at Point 1)/(21-O2 at point no 1)= false air in %

 

Regards

 

SRP.
