Bütünleşik biyokütle gazlaştırma ve katı oksit yakıt pili sistemlerinin performans, ekonomik ve çevresel analizleri

In this study, an integrated system with a SOFC and a gasifier is investigated at the system level. Initially, a zero-dimensional downdraft gasifier model was built through the ASPEN Plus program. This model calculates the molar gas composition and flow rate of syngas generated during the gasification process. Depending on the outputs of this model, the effect of the gasifier temperature on the syngas content was parametrically investigated. Secondly, zero-dimensional models for SOFC and other components are developed in the MATLAB environment. The syngas results obtained in ASPEN Plus were transferred to the system-level code created in MATLAB to simulate the performance of the system. Then, a parametric analysis was performed to examine the effect of gasifier temperature on the performance of the integrated system. Exergy efficiency was used as the performance parameter. For the baseline circumstances, exergy destruction of the system components was also examined. Thirdly, exergo-economic analysis of the integrated system with downdraft gasifier and SOFC was carried out. The effects of parameters such as gasifier temperature, SOFC stack number on cost were investigated. Finally, greenhouse gas emissions were evaluated as an environmental perspective of the integrated system.
