Effect of functional group distribution on combustion characteristics of chars from Afsin Elbistan lignite and RDF

RDF (Refuse Derived Fuel) and lignite from Afsin-Elbistan region were subjected to carbonization to produce their chars. For this purpose, these samples were heated from ambient to temperatures of 400, 500, 600, 700, 800, 900oC by a heating rate of 10oC/min in a tube furnace under nitrogen flow. Then, the chars were characterized in terms of the calorific values and the functional groups were investigated using FTIR (Fourier Transform Infrared Spectroscopy) technique. Also, some fuel blends where the chars of RDF and lignite are blended in different ratios were prepared. Effects of the charring process on the fuel properties of RDF and lignite were interpreted.
