摘要
在本文中,对某4 t/h工业煤粉锅炉进行了仿真模拟。实验变量为风率、旋流强度、煤粉粒径、循环风和计算模型。试验结果表明:风率、旋流强度与燃烧温度非线性相关;煤粉颗粒越小,燃烧效率越高;循环风和SNCR系统可有效降低NO_(x)生成;最后利用仿真结果与工程实验结果对比来验证仿真的准确性。文章对比得出了锅炉运行的最佳参数,对实际燃煤锅炉的设计和运行提供一定的理论指导。
In this paper,the simulation model of coal-fired industrial boiler was utilized.The experimental variables are wind rate,swirl intensity,pulverized coal particle size,circulating wind and calculation model.The experimental results show that:the wind rate and swirl intensity are nonlinearly related to the combustion temperature.Circulating wind and SNCR system can effectively reduce NO_(x) generation.Finally,the simulation results are compared with the engineering experiment results to verify the accuracy of the simulation.In this paper,the best parameters of boiler operation are obtained by comparison,and provide certain theoretical guidance for the design and operation of actual coal-fired boilers.
