5-2-2　Development of a predicting method for NOx generation in pulverized coal combustion

Abstract

The simulation was conducted to predict the concentration of nitrogen oxides (NOx) generated by pulverized coal combustion with accuracy and simplicity. In this study, the chemical reaction analysis software ANSYS CHEMKIN 18.2 was used to simulate a turbulent reactor. The reactor network model of the turbulent reactor was studied and the effect of Volatile N, which contributes significantly to the formation of NO, was also investigated. As a result, it was found that the NO production behavior could be roughly reproduced and that the behavior was greatly affected by the configuration of the reactor model. In order to predict the NOx production more accurately, it is necessary to establish the configuration method of the reactor network model and to study the reaction rate parameters.
