Abstract

In this study, energy and exergy analyzes were performed in the gasification of rice straw pellets prepared in 5 different blends. The heating value (LHV) of the pellets ranged from 12.45MJ/kg to 12.93MJ/kg. The calorific values of the obtained syngas samples were between 3885.5MJ/Nm3 and 4427.7MJ/Nm3. The energy efficiency of the pellet samples in gasification ranged from 53.44% to 58.01% and exergy efficiency varied from 49.19% to 53.48%. In all pellet samples used in gasification, the efficiency of exergy was lower than energy efficiency. The lowest irreversibility value in the gasification process was 36.74kW in PC5 pellet, the highest irreversibility value was 44.21kW in PRF pellet. As a result of the thermodynamic analysis of the pellet samples in gasification, it was concluded that there is no need to add any additives in the pelletization of the rice straw.
