Simulation on NOx Generation of RSP Calciner for Cement Production

Abstract:

At present, cement industry will be the third major pollution source of nitrogen oxide pollution following electric power and automobile industry. According to Chinese 12th Five-Year Plan, nitrogen oxide emission must be decreased 10%. In this paper, the resources of NOx emission from cement production were analyzed. On the basis of forming mechanism of thermal NOx and fuel NOx, a simulation model was constructed to predict NOx generation process in RSP calciner. For the turbulent flow in calciner, a probability density function (PDF) describing time variation is used in model to predict NOx generation rate. The results provide important theory evidence for low-NOx calciner design and selection of its operation process parameter.
