Fluidized Bed Boiler - an overview | ScienceDirect Topics

The circulating fluidized bed boiler (CFB boiler) is the second-generation fluidized bed boiler, the updated version of the bubbling fluidized bed boiler (BFB boiler). In this chapter, fundamental concepts of fluidized beds (including the definition and characteristics of “fluidized bed,” basic CFB boiler structure, several types of CFB

The relevance of design and feed-stock parameters to the operation of a CFB boiler are also examined, along with their impacts on designs of mechanical components, including cyclones, air

BASIC DESIGN OF CIRCULATING FLUIDIZED BED BOILER

Estimate of solid flow rate from pressure …

The effect of bed pressure drop and bed inventory on the performances of a circulating fluidized bed (CFB) boiler was studied. By using the state specification design theory, the fluidization state of the gas-solids flow in the furnace of conventional CFB boilers was reconstructed to operate at a much lower bed pressure drop by reducing bed inventory and control bed quality.

Evaluation of the performance of a commercial circulating

2013-4-22 · The Yeosu CFB boiler is different from recent CFB boilers in Korea. It is the largest CFB boiler and generates electric power only, which means that the steam quality, in terms of its temperature and pressure, is higher than other CFB boilers in Korea. The CFB boiler has been operated commercially since October 2011; however, there
