摘要/Abstract

摘要： 针对水泥窑炉生产过程中分解炉和回转窑NO_x产生的全过程,采用Aspen Plus软件建立系统仿真模型,并通过现场试验数据对模型进行可靠性验证;采用模型模拟研究分解炉中温度和燃烧气氛对NO_x的影响规律。结果表明:分解炉中温度从804 ℃变化到1 050 ℃,NO_x浓度从242 mg/m³变化到800 mg/m³,分解炉温度超过900 ℃之后,NO_x浓度会急剧上升;分解炉中CO浓度从26 mg/m³变化到990 mg/m³,NO_x浓度从585 mg/m³下降到154 mg/m³。分解炉中NO_x的浓度受回转窑中烟气温度影响较大,当回转窑中的烟气温度由900 ℃上升到1 400 ℃时,分解炉中的NO_x浓度从260 mg/m³变化到430 mg/m³。应用Aspen Plus模拟水泥窑炉NO_x的变化具有一定可行性,模型设置灵活,可为水泥窑炉NO_x控制提供参数优化和数据支持。

Abstract: Aiming at the whole process of NO_x generation in the calciner and rotary kiln in the production process of cement kilns, the Aspen Plus software was used to establish a simulation model of the system, and the reliability of the model was verified by field test data. Then the model simulation was used to study the influences of temperature and combustion atmosphere in the calciner on NO_x. It is concluded that the temperature in the calciner changes from 804 ℃ to 1 050 ℃, and the NO_x concentration changes from 242 mg/m³ to 800 mg/m³. After the calciner temperature exceeds 900 ℃, the NO_x concentration rises sharply. The CO concentration in the calciner changes from 26 mg/m³ to 990 mg/m³, and the NO_x concentration drops from 585 mg/m³ to 154 mg/m³. The NO_x concentration in the calciner is greatly affected by the flue gas temperature in the rotary kiln. When the flue gas temperature of the rotary kiln rises from 900 ℃ to 1 400 ℃, the NO_x concentration in the calciner changes from 260 mg/m³ to 430 mg/m³. It is feasible to use Aspen Plus to simulate the NO_x changes of cement kilns, and the model setting is flexible, which can provide parameter optimization and data support for the NO_x control of cement kilns.
