“…On the other hand, heat exchangers that can be used in non-clean environments are critical in recent applications. For example, the scale of geothermal utilization [8][9][10] and the solidified layer in latent heat storage (LHS) 5,6,[11][12][13][14] cover the heat exchange wall heat exchange wall and impede efficient heat transfer. The heat transfer rate decreases significantly due to the thermal resistance in the covered layer, as shown in Fig.…”

To establish a low-carbon society, it is necessary to break away from dependence on fossil fuels, and the utilization of geothermal energy/waste heat is one of the key methods. When using geothermal energy, the rate of heat transfer decreases with time due to the precipitation of scale on the heat transfer surface, and periodic maintenance is required. Therefore, the running cost of utilizing geothermal energy is high. We focused on a rotary heat exchanger consisting of a rotating cylinder as the heat transfer wall and a fixed blade attached to the rotating cylinder for scraping the heat transfer surface. In this study, the heat recovery characteristic from chloride hot spring was experimentally evaluated. The results showed that scale formation on the heat transfer surface could be suppressed and the heat transfer characteristics could be maintained for one month.
