Mechanical aspects analysis of the cyclone gasifier design via finite element method

Abstract

Cyclone gasification systems is an efficient energy recovery system from biomass. The strength of the cyclone gasifier is crucial to ensure the functionality and safety during the operation. The aim of this research is to investigate the mechanical aspects of the cyclone gasifier by using the finite element analysis. Finite element based software was employed to analyze the mechanical aspects of the cyclone gasifier. The stress and strain of cyclone gasifier’s structure was studied when increasing in the wall thickness under the different internal pressures. The maximum stress of the cyclone structure decreases to 76.2MPa from its original model when exposed to 20atm of pressure. The reduction of maximum strain was from 4.66×10−3 to 2.75×10−4 and the deformation of the cyclone body reduces to 0.217 compared to the original cyclone body at 20atm pressure. These research findings provide the information for further optimization through finite element technique without consuming a high production cost and time.
