Abstract - During the combustion of fossil fuel, emissions of NOx and SOx had many environmental problems like acid rain, corrosion effect due to the content of Sulphur in coal, etc. Concerning this, studies have been carried out to explore the ability of biomass to reduce the levels of nitrogen oxide (NOx) and Sulphur oxide (SOx). The existing study focuses on the impact of combustion using coal and biomass combined to produce ecofriendly energy production. Different ratios of coal and biomass have been used to study the combustion activity of coal-biomass blends and their emissions. In different ratios, such as 80/10, 70/20 and 60/30, and 50/40, four different biomass were mixed with coal. During the co-combustion of coal at a ratio of LC80 percent + BTW 20 percent, the minimum emissions were observed and maximum emissions were sorted at 100 percent lignite coal (LC). After the blending of coal and biomass characterization was done by using thermogravimetric analysis (TGA). For beneficial results about NOx and SOx emissions from the co-combustion process, it will be easy to decide on the use of biomass with coal. Finally, the researchers concluded that the utilization of biomass with Lignite coal may take remedial action regarding environmental damage and sustainable energy production. Less energy will be utilized through biomass combustion than coal to decrease the emission of pollution.
