Cofiring of Biomass with coal: A Perspective

摘要

Depletion of fossil fuels and its associated environmental hazards necessitated the attention towards renewable energy generation. Biomass is one of the renewable sources and available throughout the year. It includes wastes from farm and field, agro and allied industries. Utilization of these resources can generate a significant energy contribution as solid, liquid and gaseous fuels, chemicals and electricity. It had low sulfur content and reduces the reliance on fossil fuels and emissions. It can be used directly or indirectly in the existing and retrofitted systems as a substitute fuel for coal by the cofiring technology. The combined use of biomass and coal can reduce the emission as well as coal use and give value addition to the biomass. This paper reviews the cofiring of biomass with coal, technological issues and the emission reduction benefits of cofiring.
