Thermal behaviour study of senakin coal and Refuse Derived Fuel (RDF) blends during pyrolysis using thermogravimetric analysis
Preliminary Thermogravimetric (TG) studies of pyrolysed Refuse Derived Fuel (RDF)–coal blends (20 to 80%) at various heating rates, 20, 40, 60 °C•min–1 have been performed to develop an efficient locally sourced renewable solid fuel. The characteristics of the coal/RDF blends followed those of the parent fuels in additive manner. Among the tested blends, 50:50 blends showed the optimum blend ratio but no synergistic effect was observed between the coal and RDF during co–pyrolysis. However, the kinetic analysis using modified Arrhenius equation indicates the existence synergistic effect between the RDF and coal, which induces lower coal pyrolysis activation energy.
