Numerical Study on the Performance of a Cogeneration System of Solid Oxide Fuel Cell Based on Biomass Gasification

In order to solve the environmental pollution problem caused by winter heating of rural residential building in northern China, this paper a biomass gasification (BG)-solid oxide fuel cell (SOFC) combined heat and power (CHP) system has been establishedand numerically investigated. Taking village around Xi’an which is an ancient city located at central China as study object, according electricity output electrical load characteristics village, energy saving ratio economical efficiency CHP under three different operation schemes compared with traditional have analyzed. The results show that scheme for designated rooms buildings meeting average demand users most energy-efficient way. primary rate annual cost can reach 18.0% 10.3%, respectively. When user’s clear, closer system’s ratio, more significant effect.
