Cofiring of Coal and Biomass in a Travelling Grate Boiler in India

K.V. Narayanan and E. Natarajan

Concerns regarding the potential global environmental impacts of fossil fuels used in power generation and other energy supplies are increasing worldwide. One of the methods of mitigating these environmental impacts is increasing the fraction of renewable and sustainable energy in the national energy usage. A number of techniques and methods have been proposed for reducing gaseous emissions of NOx, SO2 and CO2 from fossil fuel combustion and for reducing costs associated with these mitigation techniques. Some of the control methods are expensive and therefore increase production costs. Among the less expensive alternatives, cofiring has gained popularity with the electric utilities producers. The present study discusses about the emission characteristics namely NOX, SO2, suspended particulate matter and total cost of fuel from a 18.68 MW power plant with a travelling grate boiler, when biomass was cofired with bituminous coal in 3 proportions of 200 and 60%, respectively by mass. Bagasse, wood chips (Julia flora), sugarcane trash and coconut shell are the biomass fuels cofired with coal in this study.
