Assuming that the high‐gradient magnetic separation (HGMS) system based on a superconducting magnet can reduce iron oxide scale in boiler feedwater and contribute to the efficient operation of thermal power plants, we design a new matrix structure, which should efficiently capture iron oxide particles in boiler feedwater. We then evaluate their practicability experimentally and confirm that this HGMS system with the newly developed matrix is applicable to thermal power plants with the desired efficiency. On the bases of the results, we designed practical large‐scale HGMS systems for boiler feedwater with a superconducting magnet and new matrices, which has long cleaning cycles and low‐pressure loss. © 2020 Institute of Electrical Engineers of Japan.

火力发电厂磁选系统的开发

假设基于超导磁体的高梯度磁选（HGMS）系统可以减少锅炉给水中的氧化铁垢，并有助于火力发电厂的高效运行，我们设计了一种新型的矩阵结构，该结构可以有效地捕获氧化铁颗粒在锅炉给水中。然后，我们通过实验评估其实用性，并确认具有最新开发的矩阵的HGMS系统适用于具有所需效率的火力发电厂。根据结果​​，我们为具有超导磁体和新基质的锅炉给水设计了实用的大型HGMS系统，该系统具有长清洁周期和低压损失的特点。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
