摘要
针对粮食烘干热风炉试验成本投入大、煤粉燃烧配风控制严重依赖手工调节的问题,设计了热风炉燃烧通道结构,优化了配风参数,并进行了数值模拟试验。为了验证仿真结果的正确性,建立了热风炉实际模型,按照设计参数进行了煤粉燃烧试验。通过数值仿真结果和现场采集数据对比,发现数值模拟测得温度值与现场试验测量值误差低于5%。该结果对该粮食烘干用热风炉的设计、运行和改造具有一定的参考意义。
Aiming at the problems of high test cost of grain drying hot blast stove and heavy dependence of manual adjustment on pulverized coal combustion air distribution control, this paper designs the combustion channel structure of hot blast stove, calculates the air distribution parameters, and carries out numerical simulation test. In order to verify the correctness of the simulation results, a practical model of hot blast stove is established, and pulverized coal combustion test is carried out according to the design parameters. By comparing the numerical simulation results with the field data, it is found that the error between the numerical simulation and the field test is less than 5%. The results have certain reference significance for the design, operation and transformation of the hot stove for grain drying.
