US5728357A Reduction of NOx emissions from rotary cement

The use of urea injection SNCR is enabled for rotary kilns of the type used to produce cement clinker. Rotary kilns are long cylinders that rotate about an inclined axis, with cement premix fed in at one end and a burner for heat at the other end. The geometry of the kilns and temperatures at the ends make introduction of ammonia or urea solutions ineffective or totally impractical.
