Energy, exergy, and economic ( <scp>3E</scp> ) evaluation of a <scp>CCHP</scp> system with biomass gasifier, solid oxide fuel cells, micro?gas turbine, and absorption chiller

The aim of this work is to investigate a novel integrated cooling, heating, and power (CCHP) system with biomass gasification, solid oxide fuel cells (SOFC), micro-gas turbine, absorption chiller. performance analyzed by mathematical models consisting lumped SOFC chiller one-dimensional model downdraft gasifier. Effects main operating parameters such as moisture content biomass, air flow rate in the gasifier, temperature gas on overall energy exergy CCHP are evaluated. net present value (NPV) method used analyze economic prospects system. results show that higher for gasifier lower beneficial improvement output CCHP, and, accordingly, electrical efficiency well rises. Increasing mass can increase 10%. Moisture less than 0.2 could result greater 45% over 65%.The decrease exhaust further boosts production cooling heating Specifically, 10% obtained when reduced 90°C. In work, an 50%, more 40%, up 80% be achieved. Economic assessment shows initial investment above 50%-60% total payback period about 7-8 years.
