Abstract

This study reports the simulation of rice husk pyrolysis units in various sizes of chimneys to investigate the effect of chimney diameter on temperature and heat distribution. The modeling design was carried out using Solidworks 2020 software with 3d modeling, and flow simulation features where the diameters of the chimneys were varied, namely 3, 4, 5, 6, and 8 inches. Simulation of the pyrolysis process with an input temperature of 450 °C and an average fluid velocity of 2.344 m/s for chimney diameters of 3, 4, 5, 6, and 8 inches has resulted in a condenser heat-temperature (TH) of 169.84 °C, 170.04 °C, 171.36 °C, 170.31 °C, and 168.05°C. It produces cold-temperature (TC) of 41.97 °C, 42.88 °C, 42.31 °C, 42.38 °C, and 45.35°C, respectively. The simulation results also show that the larger the chimney size of the pyrolysis tank, the greater the need for heat from the stove fire; conversely, the tank capacity of the husk becomes smaller.
