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.

A waste-to-energy conversion apparatus comprising a primary combustion chamber capable of holding a load of waste, and the primary combustion chamber further comprises a heat source to heat the waste and generate a syn gas stream, grates, within the primary chamber, capable of supporting the load of waste during heating, a mixing chamber wherein the syn gas is mixed with additional combustion gas, a multi-chambered secondary combustion chamber for combusting the mixture of syn gas and additional combustion gas, and an energy extraction system for extracting the heat energy generated by the combustion of the mixture of syn gas and additional combustion gas.
