Re: Coating formation in Kiln Inlet

Sir hello,

if you are looking to minimize build up at kiln inlet and riser duct using a preventing automatic method, i would recommend using air blasters which will be blast plant compressed air  at fixed timing (hence every 15 minutes)

 High pressure water jetting can be stressfull for refractory coating

Cardox are quite effective, but need proper storage and licence, and triggers have to be done every time manually.

  Paramount is to balance the alkali sulphate ratio but also try to avoid reducing atmosphere in the kiln . This is especially beneficial if the backend coating resulted from excess sulphur in the system. Oxidizing atmosphere wil encourage formation of SO3 which can react with the ever present CaO to form stable CaSO4 that will be expelled with the clinker.

Re: Coating formation in Kiln Inlet

Dear All ,


kindly i want to clarify info. about Alk-sulphate ( Na2SO4 & K2SO4 )

 these compounds share in build up in kiln inlet or come out with clinker ?

Re: Coating formation in Kiln Inlet


 We noticed very high sulphur content (About 3-4) % and kiln was disturbing .The increase in sulphur %  was within a period of 24 hours.What was the reason for such sudden increase in sulphur??To balance sulphur alkali ratio is it advisable to stop alkali by pass system to increase the alkali and thus balance the ratio .Pl advise.
