The denitrification rate of the cross-flow activated coke flue gas purification facility varies with operational parameters. According to the simulated experiments, the denitrification rate with the height drop of the denitrification unit experiences 100%, rapid decreasing, and gradual rising to the equilibrium. According to the correlation analysis results based on production data, several operational parameters affecting the denitrification rate have been obtained. The denitrification rate has negative relationships with the activated coke bed temperature, the flue gas flow, the H₂O content, the SO₂ content and the NH₃ slip, and has positive relationships with the O₂ content, the NO_x content, the NH₃–NO_x molar ratio, the flue gas pressure and the regeneration temperature. Properly increasing the sintering air leakage or the cooling air added into flue gas is beneficial to increase the denitrification rate. Priority should be given to O₂, NH₃–NO_x molar ratio and flue gas flow to improve the denitrification rate. Additionally, a linear model, which had been validated, was developed and can be used to predict and control the denitrification rate.

错流活化焦炉烟气净化设备的反硝化率随运行参数而变化。根据模拟实验，随着反硝化单元高度的下降，反硝化率达到100％，迅速降低，并逐渐上升到平衡状态。根据基于生产数据的相关分析结果，获得了影响脱氮率的几个运行参数。脱氮率与活性焦床温度，烟道气流量，H ₂ O含量，SO ₂含量和NH ₃泄漏呈负相关，与O ₂含量，NO _x含量，NO ₃含量呈正相关。NH_3- NO _x摩尔比，烟气压力和再生温度。适当增加烧结漏气或增加烟道气中的冷却空气有利于提高反硝化率。应优先考虑O ₂，NH ₃ -NO _x摩尔比和烟道气流量，以提高反硝化率。此外，还开发了一个经过验证的线性模型，该模型可用于预测和控制反硝化速率。
