Simulation of Biomass Gasification

Abstract:

This paper deals with the modeling and analysis of drying of biomass in gasification. Biomass is a potential alternative for fossil fuels like coal, oil etc., to sustainably meet the increasing energy needs of the world. The different methods of conversion of biomass are anaerobic and thermo chemical conversion. Since, thermo chemical conversion is a reliable one we opted to choose it. The paper deals more with the analysis of the biomass drying and heat transfer towards the inlet air for combustion. The proposed work increases the efficiency of the drying chamber by increasing the temperature of the inlet air and also it analyses on increasing the effectiveness of the heat exchanger by changing the input values by simulation. Simulation is the initiation of the real world process or system overtime. It is also used with the scientific modeling of human system to gain insight. Here simulation is carried out using MATLAB. It is user friendly and adds real time values in coding.The results are plotted in the graph shows the comparative performance before and after preheating.
