Abstract
A simple method for the rapid generation of superheated steam using a water-containing porous material was proposed in a previous paper (Mori and Okuyama, 2007). The start-up and cut-off responses are of the order of second, and the maximum energy utilization efficiency for input power is more than approximately 0.9. In the present paper, in order to clarify the process of the rapid generation of superheated steam, the steam temperature, the surface temperature of porous materials just below the wire heater, and the surface roughness of porous materials have been measured. As a result, it is found that narrow space between heater and porous material which is formed by surface roughness of porous material is one of important factors to generate superheated steam rapidly.
