Analysis of the Effect of Inlet velocity on Pressure drop on Cyclone separator to be used in Pyrolysis system

Abstract Pyrolysis is a process of chemical decomposition of biomass through heating at high temperatures (above 300°C), with no or little oxygen, which produces green fuels such as: syngas, bio-oil, and bio-char. The most important component of a pyrolysis system is the cyclone separator. The function of the cyclone separator is to remove solid particles from the syngas formed, so that the syngas becomes cleaner. Therefore, to improve the performance of the cyclone separator, it is necessary to test it experimentally. Pressure drop is an important variable in determining the performance level of the cyclone separator in the pyrolysis system. The cyclone types tested are Stairmand and Lapple types. Based on the experimental results, inlet velocity is very influential on the pressure drop of the cyclone separator. The greater the inlet velocity value, the higher the pressure drop value. The highest-pressure drop is in the Lapple type of 16.26 mbar compared to the Stairmand type of 12.16 mbar with each inlet velocity of 13 m/s.
