QUATRO-GENERATION SYSTEM

摘要

In order to provide a novel quatro-generation system having a higher total thermal efficiency than a conventional cogeneration system, this quatro-generation system (1) is equipped with: a generator engine (2) driven by fuel gas; an exhaust heat boiler (4) that uses the energy of exhaust gas discharged by the generator engine to generate steam; a boiler water recirculation device (8) that supplies steam generated by the exhaust heat boiler to a steam energy recovery means (6) and returns condensation water from that steam to the exhaust heat boiler; a condensation economizer (10) that uses condensation latent heat from the exhaust gas discharged from the exhaust heat boiler to heat a heat medium; and a heat medium circulation device (14) that supplies the heat medium heated by the condensation economizer to a heat energy recovery means (12), and returns the heat medium to the condensation economizer.
