I have two Unax cooler 4 stage SP Kiln.
Fuel 80% Petcoke & 20 % Indian Coal.
Lowst Stage Cyclone Analysis
LOI =24.44%
SO3 =2.05%
But in the III kiln which is SLC 5 stage grate cooler kiln with same fuel
Lowst stage Cyclone feeding kiln inlet sample is
LOI = 2.48%
SO3 = 5.84%
Please suggest me to use these figures & why SO3 in III kiln is very high
Does the SO3 evaporation factor helps to analyse something about buildups?
In my view we can put more percoke in Kiln 1&2 as evaporation factor is around 0.6 but in III kiln factor is 0.82 which is the limit for the buildups
Please advise
