在国内外研究基础上，依据循环流化床锅炉炉内氮氧化物（ＮＯ和Ｎ２Ｏ）的生成与分解特性，建立了一个以化学反应动力学为基础的炉内ＮＯ和Ｎ２Ｏ的生成和分解模型，模型有机地结合在已有的循环流化床锅炉总体数学模型之中。模型对一台７５ｔ／ｈ循环流化床锅炉炉内氮氧化物的生成和分解特性的模拟预测结果与工业试验结果吻合良好。模型的预测和工业试验表明循环流化床锅炉的氮氧化物（ＮＯ和Ｎ２Ｏ）的排放受锅炉运行参数如温度、一二次风比例等的影响，可以通过调整锅炉运行参数来控制锅炉氮氧化物的排放。
Based on the domestic and foreign research, based on the formation and decomposition characteristics of nitrogen oxides (NO and N2O) in the circulating fluidized bed boiler, a model of formation and decomposition of NO and N2O in the furnace based on chemical reaction kinetics , The model is organically integrated into the overall mathematical model of the existing circulating fluidized bed boiler. The model predicts the formation and decomposition of nitrogen oxides in a 75 t / h circulating fluidized bed boiler in good agreement with the industrial test results. The model predictions and industrial tests show that the emissions of nitrogen oxides (NO and N2O) from circulating fluidized bed boilers are influenced by boiler operating parameters such as temperature and primary and secondary air ratios. The boiler operating parameters can be adjusted to control nitrogen oxides Emissions.
