为了研究不同几何参数(如风口位置、送风形式等)和操作参数(如风速等)对旋流炉内流场的影响,对粉煤燃烧旋流炉的结构和操作参数进行优化,本研究是优化研究的部分内容,即用Fluent软件中RSM模型对不同进风方式、不同风口布置方式和不同操作参数下旋流炉内的流场进行数值模拟,以确定理想的结构和操作参数,其中从切向速度和轴向速度两方面证明了当旋流炉为双侧切向进风布置方式时,有利于提高旋流炉的颗粒分离率,减少壁面和风口处的结渣现象,并延长了颗粒在旋流炉的停留时间,有利于提高旋流炉的燃烧效率,为旋流炉的热态实验提供了参考。
In order to study the influence of different geometric parameters (such as tuyere position, blowing mode) and operating parameters (such as wind speed) on the flow field in the cyclone furnace, the structure and operating parameters of the pulverized coal combustion cyclone furnace are optimized. Is a part of optimization research. That is to say, using the RSM model of Fluent software to simulate the flow field in the cyclone furnace under different inlet modes, different outlet arrangements and different operating parameters to determine the ideal structure and operating parameters It is proved from the tangential velocity and the axial velocity that when the cyclone furnace is arranged in a double tangential direction, the separation rate of the cyclone furnace is increased, the slagging at the wall surface and the tuyere is reduced, and the lengthening The particle residence time in the cyclone furnace is conducive to improve the combustion efficiency of the cyclone furnace, which provides a reference for the hot state experiment of the cyclone furnace.
