G0801-2-1 Performance Analysis of Cogeneration System at Sewage Treatment Plant of Cold Region

Abstract

This study shows basic performance analysis and challenge of cogeneration system (CGS) operated by micro gas turbine (MGT) at sewage treatment plant of cold region. Especially, when biogas produced by the fermentation process in the facility is assumed to be used as fuel, whereas tendency of excess biogas is shown in summer, shortage energy for heating is shown in winter. In this study, as a one solution to the unbalance occurred, excess biogas is assumed to be stored by the methane hydrate (MH) storage method which is integrated with the whole system. While adopting an actual data as a part of the calculation procedure, results of the performance analysis are shown in this paper.
