In the present study thermal characterization of most abundantly available indigenous resources of low grade coal (Chamalang) and residue of agricultural waste (bagasse), and various Coal-bagasse blends (by weight) have been investigated, using thermogravimetric techniques. Proximate and ultimate analyses were also performed and heating values were measured. The operating parameters like heating rate (15, 20, & 40 0C/min), feed composition (85/15, 91/9 & 94/6), equivalence ratio (ER value 0.25,30 & 35) that affects the kinetics and thermal conversion process were tested using TGA in non-isothermal mode by maintaining sub-stoichiometric environment. TGA was operated from room temperatures to 950°C and it was observed that these parameters have very pronounced effects on the kinetics and conversion of these fuels. Coal-bagasse blends 91/9 (% w/w), heating rate of 20 ⁰C/min and ER value 0.30 gives the optimum conversion. These parameters also had shown a pronounced effect on the activation energy that was determined by the regression analyses of weight loss data of TGA. .

 TGA results contributed to the thermal characterization of low-grade coal, biomass as blended fuel for gasification. Therefore, understanding of proper thermochemical conversion processes for co-firing established the optimum operating conditions for the gasification reactor.
