  • Effects of Excess Primary Air in Kiln Operation - Page 1 of 1

    Re: Effects of Excess Primary Air in Kiln Operation. If the total air consumption remains the same (same %O2), the heat consumption will increase a little bit since some hot air from the cooler will be stacked. The detailled balance could be more complicated: More kiln PA should decrease the flame temperature in the kiln.

    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.

    Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the hot end where it eventually drops out and cools
