Patent ID: 7377107

Claim:
A cogeneration system, comprising: a combustion chamber; a burner installed to said combustion chamber, and inducing exhaust gas-generating combustion within said combustion chamber; a liquid media jacket enveloping said combustion chamber and containing a liquid medium to be flowed therethrough, the liquid medium being heated by the exhaust gas generated by said burner; a Stirling engine having a heater installed within said combustion chamber and disposed in opposite to said burner so as to be struck by the flow of exhaust gas in said combustion chamber, and being operated by means of being supplied a thermal energy from said heater to an operating fluid sealed therein; an exhaust gas flow channel discharging exhaust gas which flows toward said heater from said burner and supplies the thermal energy to said heater; and an exhaust gas passage having an inlet connected to said exhaust gas flow channel and directing the flow of exhaust gas along said liquid medium jacket; wherein the exhaust gas generated by burner-driven combustion flows against said heater as means of transferring the thermal energy thereto, and then flows into said exhaust gas passage, via said exhaust gas flow channel, as means of transferring the thermal energy to the liquid medium, thereby providing a mechanism through which the exhaust gas is able to simultaneously transfer the thermal energy to said heater and the liquid medium.
