Evolution of kinetic and hydrothermal study of refused derived fuels: Thermo-gravimetric analysis

Abstract

With the increase in municipal-solid-waste (MSW) production, energy usage, and the curb of the landfill, it has developed the need of our society to use local MSW under the vision of waste-to-energy (WTE). WTE conversion is an environment-friendly way for disposing of MSW around the globe, in this study examining the usage of plastic, wood, and cloth for the refused derived fuels (RDFs) production. RDF is solitary of MSW energy yields, whose reliability and superiority are analysed in the current work. Three different RDFs had been assumed from diverse waste streams accessible at the plant site to propose the best RDF based on energy-efficiency. Plastics, wood, and cloth are the principal constituents in the method of occupied RDFs like RDF-I, RDF-II and RDF-III, respectively. The results demonstrated that the RDF-I holds a high amount of carbon as-well-as hydrogen content and adequate calorific value, which leads to a better fuel-quality and have better activation energy. Thermogravimetric analysis had shown, with the increase in the volatile matter fraction of RDFs, the retention time under the combustion atmosphere has remained increased accordingly and kinetic analysis showed the great activation energy value as compared to the other samples. Regarding all results, RDF-I was recommended to be a good option for energy applications and can be used as a fuel for numerous combustion reactions.
