抛煤机链条炉增拱冷态空气流场实验与数值研究

摘要

某厂65 t/h抛煤机锅炉增设前拱后,通过数值模拟得到炉内冷态空气流场的模拟结果,并与实验测得数据相比误差较小,因此可以验证该数值模型的正确性及可靠性.并以数值模拟的结果研究增拱后炉内冷态空气动力场的特性.%After setting up the front arch on a 65 t/h stoker boiler, the numerical results of in-furnace cold air dynamic field is gotten with the help of numerical simulation. Compared with the experiment results, this model has smaller error, so the correctness and reliability of this mathematical model is beyond suspicion. Further, according to the numerical result of numerical simulation, the feature of the cold air dynamic field in the stocker boiler added front arch could be studied.
