EXPERIMENTAL AND THEORETICAL STUDY OF DRYING OF POROUS BIOFUEL MIXTURE

The paper presents a study of the drying kinetics of a porous mixture of biofuel based on the solid residue of peat after extraction and corn stalks. Experiments were performed on a convective drying stand. The effect of temperature on the duration of drying was determined. As the temperature rises, the drying process intensifies. Effective modes of drying the porous mixture of biofuel have been determined. The most adequate model was chosen for numerical simulation. A comparison of the obtained numerical results with our own experimental data showed a sufficient coincidence. The difference does not exceed 3% in temperature and 4% in humidity. The obtained results indicate that the selected model allows numerical calculations of the dehydration of porous media with sufficient accuracy.
