PURPOSE: To produce a large electrical output by arranging a thermoelectric module directly in discharge gas and heating the heating face thereof with the discharge gas.
CONSTITUTION: An engine 13 operating with fuel being fed from a fuel feed system 17 provides the output through a shaft 14 to a generator 15 in order to produce power and discharges gas after combustion. The discharge gas is led to a thermoelectric generating section 20 where the heating face of a thermoelectric module 2 fixed on the outer wall face 3a of a flat cooling pipe 3 is heated to a high temperature, then the discharge gas is discharged through a smokestack 12. Cooling water is flowing through the flat cooling pipe 3 and cools the cooling face (outer wall face 3a side of the flat cooling pipe 3) of the thermoelectric module 2. Consequently, current is produced according to the temperature difference between the opposite faces of the thermoelectric module 2 and a large electrical output can be produced.
