A techno-enviro-economic assessment of a biomass fuelled micro-CCHP driven by a hybrid Stirling and ORC engine

Stirling engines (SE) offer good part load performance and high heat sink temperatures which make it a suitable candidate to serve as prime mover in micro-combined cooling, heating power (?-CCHP) applications. In this study, novel ?-CCHP configuration hybridising SE with an ORC utilise the waste from produce additional is proposed. Additional was recovered flue gas dry biomass feedstock, fire thermal chiller hot water. Further, non-ideal model formulated implemented MATLAB while models of other subsystems were Aspen plus®. Also, control achieved by establishing connection between software A detailed sensitivity analysis conducted study influence cooling loads, rotational speed quality fuel on energy utilisation factor, primary savings (PES), CO2 emissions reduction (CO2ER) exergy efficiency system. It found that increased output standalone 66% 63.4%, respectively at its operating 2500 rpm, also improved speeds. deployment hybrid movers design yielded PES CO2ER 55% 43%, when system utilised woodchips containing 10% moisture. The proposed performs better than conventional systems producing only one vector over wide range engine frequencies, ratios compositions.
