The mechanism of NO release in the cement precalciner was analyzed and a mechanism model was developed.The NO release was simulated based on full-scale modeling for the precalciner
and the modeling results were compared with measurements to validate the simulation method.The cement raw meal inlet was relocated.Without affecting the operation
simulation was made to predict the decrease of NO under staged air
staged fuel and simultaneous staged air-staged fuel.It was found that the case of staged fuel was more effective.The results are useful for decreasing NO release in the precalciner.
