摘　　要：设计一种高倍率蓄热体结构,通过改变加热孔相对位置及增加加热孔数量,降低蓄热体结构的砖隙比,与传统型蓄热体结构的蓄热容量及最终时刻的蓄热温差进行比较及应用分析。结果表明:高倍率蓄热体结构引入正三角排列的加热孔和将砖隙比降至3.7后,目标温度下蓄热容量增加12%,最终蓄热状态的温度分布更加均匀,与传统蓄热体相比较整体温度降低9.2%,蓄热体温差降低13.6%;应用高倍率蓄热器的工程项目运行结果良好,两台高倍率蓄热器都达到理论热容量的77.5%和80.0%,仿真和实验结合方法确定合闸、跳闸温度可靠,符合设计需求。A high-margin heat storage body structure is designed to reduce the brick gap ratio of heat storage structure by changing the relative position of the heating hole and increasing the number of heating holes.The thermal temperature difference between the heat storage capacity and the final moment of the traditional heat storage structure is compared and analyzed.The results showed that after the introduction of the heating hole in the positive triangle arrangement of the heating hole and the reduction of the brick gap ratio to 3.7,the heat storage capacity at the target temperature is increased by 12%,the temperature distribution of the final heat storage state is more uniform,the overall temperature is decreased by 9.2%compared to the traditional heat storage body,and the temperature difference is decreased by 13.6%.The engineering project with high-margin heat accumulator spree is running well,and both high-multiplier accumulators have reached 77.5%and 80.0%of the theoretical thermal capacity.The simulation and experiment combination methods determine that the closing and tripping temperatures are reliable and meet the design requirements.
