This study aims at investigating the influence of hydrothermally treated municipal solid waste (MSW) on co-combustion characteristics of different rank coal. MSW blends of various proportions (on %wt), with different rank coal were tested in a Thermogravimetric analyzer (TGA). Combustion characteristics like volatile release, ignition were studied. The result shows that even though the blending of MSW with coal is favorable to initiate the early release of volatile, different ignition behavior was observed depending on the blends composition and coal rank. It is found that the effect of early volatile release by MSW on coal ignition differs and depends on quality of coal. The TGA combustion profiles showed that the combustion characteristics of some of the blends can be predicted from the weighted sum of the blend components. These experimental results help to understand and gain confidence among plant operators to promote MSW as an energy source for blending with coal.
