2018-3-21 Kiln coating reasons. Usually coatings or buildups in this area are due to an elevated sulphur cycle caused by either poor combustion in the main flame, or use of high SO3 fuels such as petcoke. The key is to ensure enough O2 at the kiln inlet to control excessive SO3 recirculation. High sulphur levels in the raw materials can also be a cause.. Also an excessive alkali/chloride cycle can be ...

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.

2019-4-25 downwards only to re-enter the kiln. Again they get driven out towards the in-let. In this way a gas cycle is created towards the inlet side of the kiln. Sulphur mixes with lime to form a spurrite-like compound (CaSO 4) resulting in coating or ring formation which obstructs movement of material inside the kiln.

Refractories play a critical, if unseen, role in both the rotary kiln lining, and the lining of the high volume static equipment areas that comprise a modern pre-calciner kiln system. The durability of the rotary kiln brick lining generally determines the duration of a kiln operating campaign.

Increasing the Alumina to Iron ratio restricts coating build-up. A similar effect is ob-served when Silica to Iron ratio is increased. A stable operation is critical for main-taining stable coating in ...
