[email protected]2020-3-18The cement calcination process suffers serious pollutant emission problems, especially nitrogen oxide NOx emission. Traditional methods mainly used physical modeling to optimize the operation of a cement calcination process for NOx reduction. However, physical modeling of NOx emission in the rotary kiln is too complicated because of the difficulties with determining model.

Disclosed is a bypass system for use with off gases that have exited a cement kiln utilized in a cement making process. The bypass system is adapted to remove both NOx and volatile components that are present in the off gases while the off gases are in the bypass duct.
More DetailsSNCR efficiency has been demonstrated to reduce NOx emission by up to 70 NOx emissions are not federally regulated, but State regulations vary from 50-90 reduction in cement plants. Stack Testing is the means for evaluating SNCR efficiency as it tests the levels of NOx released into the environment.

More Details2020-6-13A certain kiln operation stability may be obtained despite a less than perfect combustion when the clinker SO 3 alkali ratio does not exceed 1.2. Beyond that a locally-reducing burning atmosphere promotes an excessive sulfur volatilization, incompatible with the process stability and huge build-ups may rapidly clog the kiln.
