摘　　要：为了合理设计流化床蓄热装置主体外侧的电磁线圈结构,采用数值模拟的方法对流化床蓄热装置中的电磁加热线圈进行研究,分析电磁场和温度场的分布情况,优化加热线圈的结构和布置。研究结果表明:线圈的结构参数变化会导致加热效率和被加热物体壁面温度均匀度的变化,对比分析4种工况下的模拟结果,发现工况A下线圈结构设计最为合理,电磁感应加热效率较高,且加热完成后蓄热装置壁面温度分布较为均匀,有利于热量均匀的向蓄热颗粒材料传递。In order to reasonably design the electromagnetic coil structure outside the main body of the fluidized bed heat storage device,the electromagnetic heating coil in the fluidized bed heat storage device was studied by numerical simulation method,the distribution of electromagnetic field and temperature field was analyzed,and the structure of the heating device was optimized.Design,the research results show that the change of the structural parameters of the coil will lead to the change of the heating efficiency and the temperature uniformity of the heated object wall.The simulation results under the four working conditions are compared and analyzed,and it is found that the coil structure design is the most reasonable under the working condition A.Electromagnetic induction The heating efficiency is high,and the temperature distribution of the wall surface of the heat storage device is relatively uniform after the heating is completed,which is conducive to the uniform transfer of heat to the heat storage particulate material.
