This paper discusses the predictions of both emission characteristics of NO_x for various kinds of coals in single-stage combustion and NO_x reduction due to two-stage combustion upon pulverized coal combustion using the authors' method of numerical simulation reported previously. The analyses have been compared with the experiments of single-stage combustion for various kinds of coals in the laboratory of the Central Research Institute of the Electric Power Industry and our results agree fairly well with their experimental data in the laboratory. The best conditions also can be predicted with sufficient accuracy on the position of injection port as well as the injection air flow rate for over fired air in two-stage combustion.
