Description: Coal and Lignite are important fossil fuels, used for electric power generation, besides usage in the boiler of industries. They are the most demanded energy sources and their consumption has been increasing. However, there is a need to improve coal combustion performance to enhance the efficiency of the furnace and boiler. Addition of additives to both the fuels is an option and has led to focus by researchers for developing an additive. Such additives can effectively improve the combustion performance of coal and lignite. A study on the subject would contribute to providing information about the impact of additives on combustion properties, calorific value, and a hybrid technology that may use additives to modify the coal/lignite surface. Thus, the objective of this study is to relate the effect of additives on utilization and combustion performances of both the fuels. Improved efficiency and reduced emissions from coal/lignite power stations would lead to development of present and future efficient coal/lignite combustion technologies. Upgrading coal, reducing emission of NOx, SOx and particulate matter, and corrosion are some of the factors in the development of efficient coal technologies. The process may be developed through bench, pilot and full scale. It would be tested at lab scale and in actual operation.
