Abstract

Biomass gasification is the thermo-chemical conversion of biomass into a combustible gas mixture (producer/synthetic gas) through a partial combustion process with restricted air supply that is less than that required theoretically for full combustion. The status of biomass gasification has grown to be recognized as a renewable source of energy, partly because of its sustainability and carbon neutrality. Many gasifiers have different operating conditions and parameter giving each model its unique identification. System identification is about building models from data. The data set is characterized by several pieces of information relating to the gasifier. This study applied the experimental data which have four inputs from the air inlet velocity, radial temperature distribution within the combustion zone of the gasifier1,2,3 and one output is operating temperature using response surface method (RSM). Response Surface Method was used in an effort to identify an efficient operating temperature during changes in predictors.RSM explores the relationships between several explanatory variables and one or more response variables. The response surface model, multiple linear regression, quadratic model as well as cubic model were used to identify the gasifier system and results are presented. In the result, cubic model was better way from three methods to get the answer.
