Abstract

RDF is obtained from MSW waste which cannot be used anymore, which is flammable waste and is separated from parts that are difficult to burn through the process of counting, sieving, and air classification. Refuse Derived Fuel (RDF) has potential as an alternative energy source. Comparing RDF fuel and MSW fuel with a gasification process using a downdraft multi-stage gasifier. The experimental method is the proximate test and calorific value test, then the gasification process is carried out using a multi-stage downdraft gasifier. The performance indicator for RDF biomass resulted in the syngas composition of CO gas: 18.68% v, H2: 9.5446% v, and CH4: 0% v. The maximum LHV syngas is 3365.08 kJ / kg, the efficiency of cold gas is 57.19%, and the smallest tar content is 80.24 mg / Nm3. RDF can be used as an alternative energy source by using the gasification process. The results of this study can be used to optimize the further RDF gasification process.
