Abstract :

Biomass Is A Renewable Potential Energy Source Which Can Reduces Dependency On Fossil Fuels. Gasification Of Biomass Is A Chemical Process That Converts Carbonaceous Material Such As Biomass And Coal Into Gaseous Fuel Or Chemical Feedstock. This Gaseous Fuel Is Known As Producer Gas Or Syngas Which Contains CO2, H2, CO, H2O, CH4 And N2 Compounds. The Mathematical Model Is Formulated On The Similarities Between Real And Abstract System In Which Mathematical Equations Are Applied To Abstract System To Study The Real System. The Object Of The Present Work Is To Develop Mathematical Model For The Downdraft Gasifier Based On Non Stoichiometric Equilibrium Approach To Measure Producer Gas Composition And To Study The Influence Of Moisture Content, Equivalence Ratio On The Producer Gas Composition (H2, CO, CO2, CH4, N2), Final Temperature, Lower Heating Value, Cold Gas Efficiency. The Results Show That H2, CO2 Increases, While CO, CH4, Lower Heating Value And Cold Gas Efficiency Decreases With Increasing Moisture Content. Increasing Equivalence Ratio, N2 And Final Temperature Increases, While Lower Heating Value And Cold Gas Efficiency Decreases.
