Kiln Inlet Coating - Page 1 of 5 - International Cement .

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.

Secondly, unstable cement coating or sudden detachment of coating material easily leads to problems with the refractory material and can cause refractory bricks to fall off. As the protecting layer is then damaged and its thickness reduced, hot spots are formed inside the shell, which results in loss of energy and disturbed kiln operation.

Cement Kilns: Wet and semi-wet process kilns

Material spilled at the kiln inlet and cyclone dust, both of which were plentiful, were usually returned at the kiln inlet. The partly dried material produced by the calcinator was intended to be fairly wet (around 12-15% water) in order to retain "nodule strength" and minimise dust generation in the kiln.
