Proximate and Calorific Value Analysis of Selected Industrial Waste

The choice of a solid fuel depends on its characteristics, combustion system, operating cost, maintenance, transportation and storage. Proximate analysis and calorific value are among the most important ones. Selected Combustible industrial wastes samples collected from different industries were analyzed for their proximate and calorific value analysis according to ASTM (American Society for Testing Materials) standards. The higher calorific value which is due to higher volatile matter and fixed carbon in the sample is desired for power generation while low moisture and ash content should be there. The ash contents are highest for polymer and leather wastes so instead of having higher calorific values have the problem of ash handling which is undesirable in combustion system and increases the cost too.
