Thermogravimetric Assessment of Combustion Characteristics of Blends of Lignite Coals with Coal Gangue

In this paper, the co-combustion behaviour of lignite coal with coal gangue and coal are investigated by a thermogravimetric analysis (TGA) in the temperature range from ambient temperature to 1000 degrees C. The thermal characteristics and kinetics of lignite coal, coal gangue and their blends are evaluated under combustion conditions using a non-isothermal thermogravimetric method (TGA). Lignite coal is blended with coal gangue in the range of 25-75 wt. % to evaluate their co-combustion behaviour. Such attempts of Combustion characteristics index under different proportions of analysis may help to identify appropriate blend proportion for a given coal gangue and to derive some specific advantages with respect to particular combustion practice.
