Calcination degree of hot meal

Dear all,

The calcination degree is calculated from the L.O.I of kiln feed and L.O.I of hot meal. What if a significant amount of clinker dusts with low L.O.I is carried over from the kiln and contaminate the hot meal sample?

How to estimate the error and estimate the real calcination degree?

Kind Regards,

First of all u shuld calculate the %age of Kiln dust in flue gases.

Then find the L.O.I of Kiln dust (X) then subtract it from the L.O.I of Hot meal then calculate D.O.C

X= (L.O.I of Kiln dust* %age of Kiln dust) /100

For academic purpose it is OK to know the amount of kiln exit dust but otherwise si do not understand how it will help you in operation. Generally 2% is dust load in kiln exit gas
