Abstract:
The biomass densification process of wood particles in an industrial stamp briquetting machine with a throughput of 60 kg/h was investigated numerically. The aim was to analyze the influence of pressure and retention time on particle density. Furthermore, for the study, the pressure distribution in the forming mold was calculated. Systems of equations were created using Newton's law and Hooke's law. The resulting nonlinear system of equations was solved iteratively using the Taylor function. Due to wall friction, both increased (upper region) and decreased (lower region) pressures occur on the walls of the forming mold. These effects decrease towards the center of the forming mold. Validation was performed using the densification pressure of the briquetting machine, which was determined during the agglomeration process, and the briquette density. The agreement between the calculation results and the validation tests is 99.8%.
