MODELING OF ENERGY CROPS GASIFICATION BASED ON EXPERIMENTAL DATA

The paper presents a mathematical model of the selected energy crops gasification. Firstly, the experimental study of the biomass gasification process using fixed-bed reactor was conducted. The highest calorific value was obtained from the gasification of Miscanthus x giganteus (3.84 MJ/m³_n). Based on the experimental results, a model of the gasifier built in Aspen Plus was verified. The developed mathematical model of the gasification system properly reflects the processes occurring in the analyzed gasifier. The relative differences of the lower heating values from the model and experiment did not exceed 1%.
