Performance evaluation of mixed RDF and rice husk gasification in a bubbling fluidized bed gasifier

Municipal solid waste (MSW) management has significant impacts on humans, ecosystems, air quality, and land. Thermal treatment is the conventional method for converting waste energy into electricity. To address these issues and increase energy production, pyrolysis and gasification methods have undergone significant evolution. Use of refuse-derived fuel (RDF) is the correct path to get more resources back from MSW in developed countries. A pilot-scale bubbling fluidized bed gasifier capable of processing 5 to 15 kg/hr has been developed for the utilization of dry solid waste and other rice husk biomass. Various categories of solid waste materials were utilized in the gasification process, and the associated gas attributes, including gas quality, gas quantity, and calorific value, were examined during the tests. The characterization of the available RDF material shows that the sulfur content of the waste material was high, and to reduce it, rice husk has been mixed in different proportions. It was found that a 20% mixing of rice husk in pulverized RDF material yields promising results. The percentage of CO increased from 12.5% to 13.4%, and H 2 rose from 11.2% to 13.2% in a produced gas with the mixing of rice husk at a ratio of 20 to 80%. Mixing rice husk with a pulverized RDF material provides a promising solution for air gasification in a fluidized bed gasifier. GRAPHICAL ABSTRACT
