Yes, there is a relationship between low kiln inlet O2 and the appearance of boulders. Low O2 in the kiln inlet is known to increase the volatilisation of sulphur in that area. This subsequently increases the chances of buildups, which often fall into the kiln inlet as solid slabs.

Jan 30, 2018 · Boulder formation mechanism: Large clinker balls initiate and grow behind a thick coating or ring. Build up often fall and slide into the kiln as large slabs and coming to rest behind a ring (if it is large enough). The slab can roll around behind the ring forming a ball which can then grow larger due to accretion.

Sep 11, 2009 · The kiln need to be stopped for every week to break the ring. This was overcome reducing the hot primary temprature from 150 deg C to 90 degC by diluting with fresh air. Higher burning zone temperature would cause the liquid phase formation in the preburning zone itself which would be cooled and formed as ring.

Therefore, when SM is too high, nodulization becomes weak and clinkerization reaction (C3S formation) rate slows down, kiln becomes dusty and difficult to operate. While as when SM is too low, more melt is formed in kiln, issues like thick kiln coating, kiln melting, snowman formation in cooler are more prone. Normal range of SM is 2.3-2.7.
