Heat exchanger apparatus using porous material, and ceramic engine provided with supercharger driven by thermal energy recorded from exhaust gas by the same apparatus
First Claim
1. A ceramic engine comprising a combustion chamber having a heat insulating structure;
- a first heat exchanger provided in an exhaust pipe for discharging an exhaust gas from said combustion chamber to heat steam to a high temperature by the thermal energy of said exhaust gas discharged through said exhaust pipe;
a second heat exchanger provided in said exhaust pipe downstream from said first heat exchanger to heat up water to convert water to steam, which steam is fed to said first heat exchanger; and
a steam turbine supercharger driven by said steam generated by the thermal energy of said exhaust gas which is provided with a steam turbine driven by the high temperature steam from said first heat exchanger, and a compressor driven via a driving shaft of said steam turbine, and which is adapted to supply pressurized air from said compressor to said combustion chamber;
wherein said first heat exchanger comprises a first exhaust gas passage and a steam passage isolated from said first exhaust gas passage by partition walls to allow said steam fed from said second heat exchange to flow through said steam passage; and
wherein said second heat exchanges comprises a second exhaust gas passage and a water passage isolated from said second exhaust gas passage by partition walls to allow said water to flow through said water passage.

Abstract
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.
