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.
