Abstract
The circulating bed combustor represents an alternative concept of burning coal in fluid bed technology, which offers distinct advantages over both the current conventional fluidized bed combustion system and the pulverized coal boilers equipped with flue gas desulfurization. This paper presents the conceptual design of a circulating fluidized bed coal combustor to be used as a steam generator for a power plant. The design variables are selected to optimize the combustor's performance, size and cost. Some advantages of the combustor include good turndown capabilities, high throughput and simplified feeding. The combustor may also be used for burning various dirty fuels in industrial applications.
