Effect of O2 gas injection on SRF solid waste of dual reactor of fluidized bed gasifier.

This study uses solid refused derived fuel (SRF) from municipal waste in a dual-reactor fluidized bed (DRFB) for the gasification process. Gasification which separates the process of endothermic and exothermic reactions is the focus of the development of gasification technology today. In addition to optimizing fuel conversion, the DRFB system can also recirculate the combustion gas, namely CO2, to the gasification reactor as a function of the gasification agent (CO2 loop). In this study, oxygen (O2) was used as an agent gas to reduce the appearance of NOx emissions when using air and to increase the production of CO syngas. The gas composition of the agent was varied from no oxygen (I), 25% oxygen (II), 50% oxygen (III) and 75% oxygen (IV). The city waste RDF used has a composition of 94% organic and 6% inorganic with a size of 1-5mm. The performance results were obtained in variation III with the highest solid to gas conversion (FCR) value of 0.685 kg/hour with a syngas composition value of CO=4.25%; CH4=1.73% and H2=16.43% and a gasification efficiency value of 48.99%.
