<p>This invention provides a heat exchanger apparatus having heat exchangers(2,3) provided in an exhaust passage(8) and comprising a porous material of an improved heat exchange efficiency, and a ceramic engine(1) provided with a supercharger(4) comprising a steam turbine(7) driven by the steam generated in this heat exchanger apparatus. The heat exchanger apparatus mentioned above comprises a high-temperature heat exchanger(2) having a steam passage(26) provided in an exhaust gas passage(28) through which an exhaust gas(G) passes so as to heat steam(LS) therewith, and a low-temperature heat exchanger(3) provided in the portion of the exhaust gas passage(32) which is on the downstream side of the high-temperature heat exchanger(2) and having a water passage(34) for heating water(W) by the exhaust gas(G). The exhaust gas passage(28,32) and steam passage(9,18, 26) are packed with porous members(27,29,33) having open pores through which a gas passes. The ceramic engine(1) has a steam turbine type supercharger(4) provided with a steam turbine(7) driven by the steam(HS) from the high-temperature heat exchanger(2), and a compressor(6), and a condenser(5) adapted to separate a fluid(F) discharged from the steam turbine(7) into water(W) and low-temperature steam(LS). The pressurized air(PA) from the compressor(6) is supplied to the combustion chamber(13), and presses downa piston(14) to carry out compression work during a suction stroke. <IMAGE></p> |
