Abstract:

We have been developing a scale removal system utilizing a superconducting magnet that can remove the iron oxide scale from the boiler feed-water in the thermal power plants. Scale removal can prevent a decrease in the power generation efficiency and contribute to reduce the carbon dioxide emissions. In our previous study, we conducted the large-scale experiments for practical use, but model particles were intensively captured by the inflow side filter. In this paper, we succeeded to homogenize the distribution of captured particles in the filter stacks by controlling the applied magnetic field strength. In addition, magnetic field strength dependency of filter blockage was examined in the lab-scale experiments to clarify a detailed mechanism of blockage.
