摘要：The article presents the results of studies of torrefied willow (Salix viminalis L.) compaction.Densification tests were performed using a hydraulic press with a maximum pressure of 216 MPa.The effect of basic parameters of the briquetting process (pressure and temperature) on mechanical parameters of manufactured briquettes were determined.On the basis of the research, it was found that the increase in pressure and temperature of the densification process increases the density and strength of pressed briquettes.The positive effect of temperature is particularly noticeable at lower pressing pressures (36 MPa – 72 MPa).In the case of a temperature of 300 °C, the increase in a pressure from 144 MPa to 216 MPa resulted in the decrease in the density and strength of the briquette.It was also found that the briquettes manufactured at this temperature are characterized by lower density and strength than the briquettes obtained at a temperature of 200 °C.
