PURPOSE:To upgrade the conversion efficiency from thermal energy to radiation energy and improve its generation efficiency of electricity by lowering the temperature of a combustion exhaust gas and reducing the principal part of sensible heat difference to radiation energy on the upstream side having a low temperature heat receiving body when the combustion exhaust gas passes the inside of a radiator. CONSTITUTION:The radiator 3 made of a porus solid is centered in the thermoelectric and photoelectric generation part and a combustion chamber 19, a vacuum space (or air preheating space) 20, a photoelectric conversion element 5, a reflecting mirror 21, a cooling water path 22 are formed at the periphery of the radiator. The reflection mirror 21 allows a radiation energy having wavelengths which are not absorbed in the photoelectric conversion element 5 to return to the side of the radiator 3 and its radiator 3 is heated and then, heat retaining energy is produced. In other words, when the exhaust gas passes through the radiator 3, the temperature of its exhaust gas is lowered and also the principal part of sensible heat difference is reduced to the upstream side having a low temperature heat receiving body as radiation energy. As a result, the conversion efficiency from partial energy corresponding to the above reduced one to radiation energy is upgraded and the generation efficiency of electricity is improved. |
