Heat exchanger apparatus using porous material, and ceramic engine provided with supercharger driven by thermal energy recorded from exhaust gas by the same apparatus

摘要

A heat exchange apparatus has heat exchangers comprising porous material of improved heat exchange efficiency provided in an exhaust passage, and a ceramic engine provided with a supercharger comparing a steam turbine driven by the steam generated in the heat exchanger apparatus. The heat exchange apparatus comprises a high temperature heat exchanger having a steam passage provided in an exhaust gas passage through which an exhaust gas passes whereby steam is heated, and a low temperature heat exchanger provided in the portion of the exhaust gas passage on the downstream side of the high temperature heat exchanger which has a water passage for heating water by the exhaust gas. The ceramic engine has a steam turbine type supercharger provided with a steam turbine driven by the steam from the high temperature heat exchanges, a compressor, and a condenser which separates a fluid discharged from the steam turbine into water and low temperature steam. Pressurized air from the compressor is supplied to the combustion chamber, which presses down a piston to carry out compression work during an intake stroke.
