Investigation on the Combustion Behavior of Coal at
Various Level of Washing in TGA and Drop Tube Furnace.
Transactions of the Indian Ceramic Society, 78 (4).
pp. 181-186.
Abstract
Cleaning of coal resulted in ash reduction, heat value enhancement, increased reactive maceral content and change in ash composition influencing combustion performance.
With washed fractions, trends of improved combustion behavior were observed in thermo-gravimetric analyser, which was not always reflected correspondingly in bench
scale combustor, i.e. drop tube furnace (DTF). Lower burnout efficiency in DTF was observed when top port char particles were totally masked by defused mineral matter.
Higher burnout efficiency was observed with tenui ballon/ sphere type of char structure partially covered by defused mineral matter. Overall improvement of combustion
performance also led to CO2 emission reduction.
