Abstract:
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; anda 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; andwherein 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.
