PURPOSE: To improve power generating efficiency by reducing heat being diffused outside. CONSTITUTION: A lower radiation converting body 5 which is arranged in an internal structure 1 used so far and is formed of a porous body to heat supply air, is newly arranged at intervals under an upper radiation converting body 4, and an air preheating porous body 7 is arranged under it by interposing a first header 8. Supply air introduced under the lower radiation converting body 5 from outside is newly heated by passing it through the lower radiation converting body 5 and the air preheating porous body 7 heated at a high temperature in the upper internal structure 1. It is introduced to an air side regenerative heat exchanger 12 by a second header 9 arranged under the air preheating porous body 7, and is further heated by exhaust air, and is supplied into the internal structure 1 in which a power generating part is formed. |
