Coating formation in Kiln Inlet Page 1 of 3

Jun 11, 2008 Re: Coating formation in Kiln Inlet. Hi. Coating at kiln inlet ia mainly due to the volatiles like Chlorides, alkalies ( Na2O and K2O) and SO3. To minimise the coating formation, the alkali sulfate ratio should be around 1.1 so that these volatiles will come out as alkali sulfate along with the clinker so that the recirculation inside the kiln circuit will be less.

Re: Kiln Inlet Coating. Hello Dogra, 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.

Cement kiln Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

When the kiln moves radially or wobbles, tensioning ropes fitted with counterweights press the graphite blocks onto the slide ring. An air-cooled sealing casing minimizes thermal effects on the graphite blocks. The fastening system on the inlet and outlet sides of the kiln compensates for age-related wear irrespective of the make of kiln.
