A304 DEVELOPMENT OF AN ENVIRONMENT SYMBIOTIC MICRO COGENERATION SYSTEM FOR SUSTAINABLE MARINE CITY

Abstract

Feasibility of a novel environment symbiotic micro cogeneration system for residential purpose has been investigated for Sustainable Marine City that we call SuMaC. SuMaC is a fictitious reclaimed island (800-900 ha) on Osaka bay coastal zone with 39,000 residents. Thermodynamic analysis was carried out for the micro cogeneration systems consisting of a micro gas turbine, a micro gas engine and a polymer electrolyte fuel cell as topping and a single effect absorption chiller as a bottoming, in which natural energies are highly utilized. And their performances and efficiencies were predicted quantitatively. Total efficiency of the system exceeds 80% when the micro gas turbine or micro gas engine was used as a prime mover. And feasibility of the proposed environment symbiotic micro cogeneration system was verified by computer simulation.
