<p>PURPOSE:To reduce power cost, by converting the waste heat in exhaust gas to electric energy by arranging a thermoelectric converter element to recover the same and using said electric energy as the power supply of electric machinery. CONSTITUTION:After printing paper 2 is dried, the generated exhaust gas is sent into a deodorizing apparatus 3 to be reheated by a burner 5' and subjected to decompositional reaction by a catalyst to generate exhaust gas. The temp. difference between this exhaust gas and the open air passing through an open air duct arranged in close vicinity to said reaction exhaust gas is utilized and heat energy is converted to electric energy by a thermoelectric converter 6 having a thermoelectric converter element to recover waste heat. The thermoelectric converter 6 is constituted of the plate-shaped thermoelectric converter element and the heat conductors extended from both ducts are arranged so as to be brought into contact with the surface of the thermoelectric converter element. The thermoelectric converter element is a semiconductor capable of converting heat to electricity or converting electricity to cooling energy.</p> |
