This paper examines the inherent differences between a pulverized coal fired unit and a circulating fluidized bed unit, based on fuel properties, ash properties, and characteristics of combustion and heat transfer to determine generic advantages in fuel flexibility of a circulating fluidized bed combustor. This paper also examines how load control and fuel flexibility may be achieved based on the experience Bechtel gained from the first 650,000 pounds per hour circulating fluidized bed boiler project. The conclusion of this paper addresses the economic merits of having flexibility built in during the design phase of a circulating fluidized bed unit.
