sulphure ring in kiln 14 to 22 meter

Dear Ted

Please find enclosed sulphure balance for our pyro section which is clearly shown 22% sulphure not balalnce in system and recirculate.

we are continue facing coaing and ring formation in kiln between 14 to 22meter and every 7 to 8 days we have to stop the kiln and clean the coating manually.

please suggest what are the measures we have to take to control the coating formation, We have KHD pulsjet burner but by adjusting swirl and axial still there is no impact on reduction in coating formation.

 

please suggest any specific burner setting required.

please ask in case any specific data required foranalysis

please find the sulphure balalnce:-

There is one simple way, you control volatile factor below 2 , ie. VF=clinker SO3/ previous hour KF DC sample SO3.
