UNCONTROLLED NOX EMISSIONS FROM CEMENT KILNS In cement manufacturing, conditions favorable for formation of NOX are reached routinely because of high process temperatures. Essentially all NOX emissions associated with cement manufacturing are generated in cement kilns. In cement kilns, NOX emissions are formed during fuel combustion by two ...
Power and fuel costs account for ~30% of the price of cement when it''s sold. As a result, power and fuel have a major impact on the company''s operating expenditure. Coal is used to fire the kiln.
In a directfired cement kiln, air used for conveying pulverized coal from a coal mill,, primary air, is typically 17 to 20 percent of the total combustion air. The amount of primary air may be reduced by separating the coal mill air from coal. A cement kiln using less than 10 percent of primary air is an indirectfired kiln.
Kiln plants with two and three station rotary kilns from KHD Humboldt Wedag are top of the line. One reason: highly efficient precalcining systems, which were developed by KHD Humboldt Wedag, revolutionizing the clinkering process. Rotary kilns no longer have to function as calciners which mean that they can be substantially smaller in size.
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.

High temperature refractory cement is used for making kiln repairs including broken kiln bricks, filling cracks in kilns, and other damage that occurs during the life of a kiln. The cement is also useful for preventing dust on kiln lid surfaces from falling into the kiln. Dilute the cement with water and apply with a brush for best results.
