Energy and exergy analysis of a CI engine based micro-trigeneration systems fueled by alternate fuel blends
Conventional energy sources are limited, whereas the energy demand is increasing exponentially. There is immediate need to develop efficient systems to extract more useful energy from the same fuel input. Cogeneration and trigeneration systems use waste heat from prime movers to produce more useful energy than conventional methods in the form of heat and cooling. In this paper, an experimental and simulation based study of compression ignition engine operated micro-cogeneration and trigeneration systems working on diesel and other vegetable oil based fuel derivatives is presented. The energy and exergy analyses of both the cogeneration and trigeneration systems were done. The results obtained with base line diesel show that the overall thermal efficiency was 79.43% for cogeneration and 78.64% for trigeneration. The exergy efficiency of the system was found to be 32.80% for cogeneration and 33.08% for trigeneration. The system was modeled and simulated using TRNSYS, and the simulation results were compared with the experimental results for the validation. The improved system model for trigeneration was developed using TRNSYS to determine the scope for improvement, and it was found that it achieved the energy efficiency of 89.20% and the exergy efficiency of 45.94%.
