what should be the allowable SO3% in kiln feed?
wilfredzieri
the max. SO3 level has to be seen with several other indicators
preheater kiln: alkali/sulfur ratio = 0,5 ; max. %SO3 in clinker = 1,7
calciner kiln: alkali/sulfur ratio = 0,4 ; max. %SO3 in clinker = 2,0
total of Cl% + SO3 % in hot meal = 3,1%
Please note this is based on experience only and may vary from kiln to kiln or operating philosphy; therefore it shall be taken as a starting guidline
