Abstract
These days, industrial waste recycling becomes more important and inevitable for environmental aspects. For example, the black powder called "Itomuka Zinc Calcine" which is produced in the recycling process of used dry-cell battery, has been unused for long period, because its effective reuse method has not been found. As for thermal power stations, some portion of clinker ash which is ordinarily produced from coal-fired boilers has not been wholly-recycled. Therefore, we tried to find effective utilization of two sintered porous materials, Itomuka Zinc Calcine and clinker ash, respectively. In the present study, water evaporation rates of those materials have been investigated on the point of thermal and physical properties. As a result, it is found that both sintered porous materials had higher evaporative performance, compared to the commercial water retention block.
