Abstract
There have been a great number of investigations on kinetic model of NOx reduction reaction. However, it was found that it is difficult to apply the reaction model conveniently in the comprehensive numerical simulation of fluidized bed combustion due to the complexity of the kinetic model. Therefore, it is necessary to establish a simplified overall reaction kinetic model to adapt to the complex simulation computation of fluidized bed. In this paper, the Arrhenius coefficients of the overall reaction of NOx reduction were obtained by comparing with detailed mechanism model and optimized by using a genetic algorithm. The result showed that the overall reaction model can predict the change of NOx reduction reaction temperature window, the denitrification efficiency and the ammonia slip accurately.
