Influence of RDF MSW Composition Percentage on Fuel Conversion Rate during Coal Co-Firing in a Dual Fluidized Bed Co-Gasification Reactor

Abstract

Gasification using the Dual Reactor Fluidized Bed (DRFB) technology has emerged as a promising alternative for converting
various types of fuels—including waste, biomass, and low-calorific fossil fuels—into usable energy. This technology utilizes
two reactors: a combustion reactor and a gasification reactor. In the combustion reactor, an exothermic reaction occurs to
generate heat, which is then utilized to support the endothermic gasification process in the second reactor. This research aims
to evaluate the performance of co-gasification in a Dual Reactor Fluidized Bed system by co-firing coal with RDF derived
from Municipal Solid Waste (RDF MSW) in varying composition percentages of 0%, 5%, 10%, 15%, and 20%, using a total
fuel mass of 600 grams. Based on the results of the study, the following conclusions can be drawn. The greater the addition of
RDF in the coal co-gasification process, the higher the Fuel Conversion Rate (FCR) achieved
