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.

Age and condition of the kiln shell: Old kilns shells have been exposed ... It is an oxygen injection system connects to kiln burner or precalciner burner to enhance the combustion of the fuel. In ... The oxygen enrichment technology is established in some cement plants in order to improve production capacity. An increase of 25 ...
Kiln: Big oven for making of cement. LSF: Lime saturation factor. A higher LSF means higher specific energy consumption, the material becomes harder to burn. Clinker: The product is taken out of the kiln and is later on ground to cement. Clinker factor: This is a fraction of what is put into the cyclone system as raw meal and taken out as clinker.
The advanced burners reduce the loss in production. during kiln disturbances and also reduce NOx in the burning zone as the primary air ratio is low. The NOx. emissions can be reduced a s much as ...
Position Of Cement Kiln Burner. Burner Positions. Sep 09, 2010 Re Burner Positions The optimum position depends on many factors In the past, it was common practice to point the burner a little bit down compared to kiln axis, in direction of the chargeThis was primarily done to compensate the tendency of the flame to go upward due to convection and entrainement by the secondary air.
