A semi-empirical approach to the thermodynamic analysis of downdraft gasification

For most commercial biomass gasifiers the cold gas efficiency makes up 50–70%. However, thermodynamic modeling demonstrates the possibility of its increase to 80–85%. Thermodynamic models predict an optimal composition of flows coming to the gasifier, and a temperature. These parameters are hard to reproduce at gasifier since they often depend on the operating parameters. This paper proposes a semi-empirical approach which makes it possible to carry out a thermodynamic analysis of operating parameters...
