co-combustion analysis of lignite coal and groundnut shell using tga

The technology of co-firing was used to study the combustion of groundnut shell and coal at three different ratio of biomass (10%, 20%, and 30% in weight) and combustion of miscanthus and coal at three different ratio of biomass(10%,20%,30%) using thermo gravimetric analysis (tga). when compared to firing of coal, the co-firing of coal and biomass (groundnut shell, miscanthus) has shown a good combustion result. the ignition temperature (ti) burnout temperature (tf) is reduced in the co-combustion when compared to the combustion of coal alone. the best blend ratio of coal/groundnut shell is 80%/20%. the best blend ratio of coal/miscanthus is 70%/30%.
