Abstract:
A cogeneration system using micro gas turbine waste-heat gas, comprising:a micro gas turbine; a driving portion comprising a high-temperature-side hydrogen storage alloy container and for absorbing hydrogen through heat exchange between said high-temperature-side hydrogen storage alloy container and a cold-heat heat medium, said driving portion being capable of releasing hydrogen through heat exchange between said high-temperature-side hydrogen storage alloy container and waste-heat gas from said micro gas turbine; and a cold heat output portion, connected to said driving portion so that hydrogen can move therebetween, comprising a low-temperature-side hydrogen storage alloy container and being capable of absorbing and releasing hydrogen by use of said low-temperature-side hydrogen storage alloy container in accordance with the operation of said driving portion to generate cold heat, and transmit said cold heat to a cooling heat medium to thereby externally supply said cold heat through said cooling heat medium, wherein said heat exchange between said high-temperature-side hydrogen storage alloy container and said waste-heat gas from said micro gas turbine is a direct heat exchange.
