摘要
针对SCR系统建立κ-ε湍流计算模型,通过研究速度场、温度场及NH3浓度分布场得到硫酸氢铵的生成条件。结果表明喷氨系统后氨-烟气混合温度低于硫酸氢铵露点,是造成系统硫酸氢铵生成的原因。
The formation mechanism of the ammonium bisulfate in the SCR flue gas denitrifieation process was studied. Based on the characteristics of ammonium bisulfate, the model of SCR was built through the standard formulation of the κ-ε. The distributions of the velocity, temperature and concentration of NHs were calculated to study the formation eondi- tions of ammonium bisulfate. The results showed that the temperature of NH3-flue gas mixture ejected from the ammo- niainjeetion pipe was below the clew point temperature of ammonium bisulfate, which generated liquid and adhesive am- monium bisulfate.
