PURPOSE:To efficiently recover sensible heat of waste gas as electric energy by disposing a thermoelectric element in a circulating system for circulating heat medium and recovering the pyroelectric power. CONSTITUTION:Heat medium is fed through tubes 30, 31 to a heat exchanger 4, but a thermoelectric element electrically coupled to the outer periphery is disposed in the exchanger 4, a plurality of single tubes having water passages at the center are gathered to form a multitubular heat exchanger. Accordingly, the medium supplied through a heat medium dump tank 8, a supplying pump and a circulating pump becomes high temperature medium of approx. 300 deg.C in a heat receiver 3, is circulated to the exchanger 4, thermally exchanged and electric energy is recovered. |
