<P>PROBLEM TO BE SOLVED: To provide a heat recovery utilization system in which waste heat can be efficiently utilized. <P>SOLUTION: The heat recovery utilization system 100 is applied to a drying apparatus 200. A channel switching mechanism 301 is installed which switches a channel of hot air (first fluid) exhausted by a hot air exhausting mechanism 204 to a channel for introduction to the heat recovery utilization system 100, and hot air is introduced to the heat recovery utilization system 100. Hot air (second fluid) which is circulated by utilizing heat recovered from hot air is heated and applied to a heating step 302. Inside a drying chamber 203, as a material M, a paper sheet coated with a coating liquid obtained by mixing a heat sensitive material which is colored by heating and an aqueous solvent is dried by hot air at 160°C and hot air at 120°C is exhausted from the drying chamber 203. <P>COPYRIGHT: (C)2012,JPO&INPIT |
