Abstract
A cremation system has an exhaust gas/warm water heat exchanger which exchanges the heat of exhaust gas from a re-combustion furnace with the heat of a medium, and a buffer tank and flow rate regulating valves for suppressing temperature changes of the medium. A medium turbine is driven by an evaporator which generates working medium steam by heating and evaporating a low-boiling working medium with the heat of the medium, and power is generated by a power generator. A buffer tank is further provided to suppress temperature changes of the medium flowing from the evaporator into the exhaust gas/warm water heat exchanger. A power control device supplies the generated power to devices constituting the cremation system, while covering any shortfall in power required by the devices with power from an external power source.

(canceled)
A cremation system comprising:
- an incineration furnace for combusting a body;
- an exhaust gas/medium heat exchanger into which exhaust gas from the incineration furnace flows and which exchanges the heat of the exhaust gas with the heat of a medium;
- a first buffer tank into which the medium is injected and which controls temperature fluctuations of the medium;
- an evaporator which generates working medium steam by heating and evaporating a low-boiling working medium with the heat of the medium from the first buffer tank;
- a medium turbine which is driven by the working medium steam;
- a power generator which is driven by the medium turbine and generates power;
- a second buffer tank into which the medium flowing out of the evaporator is injected, and which suppresses temperature fluctuations of the medium and supplies the medium to the exhaust gas/medium heat exchanger;
- and
- a power control device which supplies power generated in the power generator to devices constituting the cremation system, while covering any shortfall in power required by the devices with power from an external power source.
