Impact of Fuel Variability and Operating Parameters on
Biomass boilers provide up to one-third of the energy requirement in pulp and paper mills by burning hog fuel, which is a mixture of wood-waste available at the mill site. The quality of this fuel varies significantly depending on its source and storage conditions. This fuel variability often causes biomass boiler operation to be unstable and unpredictable. This study consists of two parts
