?? Unusual

Hello Hussaini,

Normally these are not called 'snowmen' but rather 'rhino horns' (for obvious reasons) and are the result of high-alkali dust accumulating and then solidifying on the top of the burner pipe in the shape of a horn.

If the 'horn' grows too heavy it can cause the burner to go out of alignment or in worst case even damage it internally. Where this type of buildup happens I have seen that the remedy is to carefully shoot off the 'horn' with kiln gun, blasters or other such method, before it gets too big. Excessively dusty kilns are more prone to this type of buildup.

If the burner gets too far out of alignment or is damaged, then it is not too difficult to imagine that the result would be CO in the back end of the kiln.

Regards,

Ted.

Dear Ted,

Little confusion. Alkai dust should have moved to inlet rather than outlet with air momentum.

Moreover, why reducing conditions in kiln cause dusty kiln conditions. May be FeO does not favour melt formation. Am i right?
