The combustion of coal creates many environmental and health problems, apart from it has many problems associated with the power plant combustor during the use of coal with the impurities. Biomass utilization could be the best option for the use as co-feed with coal. Coal biomass co-combustion was observed in this work, and different blends of coal and biomass were prepared. Banana tree waste, cow dung, and tree leaves were selected as biomass fuel for this study. It was observed that the coal biomass blend has less emission gases as compared to raw coal, and the amount of CO, CO2, and SO2 was reduced that was in higher amount in raw coal. At a ratio of 60% of Lakhra coal and 40% of cow dung manure, the lowest of CO emission was observed, that was 580 ppm, and at the ratio of 60% of Lakhra coal, 40% of tree leaves. The SO2 emission was reduced from 377 to 170 ppm. Minimum carbon monoxide was observed for the blend of 70% Lakhra coal and 30% cow dung manure. The calorific value of biomass was increased with coal bland the bland of 70% Lakhra coal and 30% cow dung has the highest calorific value. Also, the thermogravimetric properties were increased in the coal biomass blend. The mass reduction was slow at the start while it was suddenly increased in zoon one from temperature 0 to 200 ?. while zoon two from 200 to 800 ? mass reduction was increased with higher rate and zoon three mass reduction was stopped.
