fluidized bed boiler in fluid mechanics

2013-4-2 · The term circulating fluidized bed was first applied to alumina calciners (Reh, 1971), but many other synonyms have been used to describe this system: fast fluidized bed, riser reactor, entrained bed, transport bed, pneumatic transport reactor, recirculating solids

Based on the Eulerian multiphase fluid model,3D numerical models were established to simulate the coal gasification in fluidized bed.The gas phase was modeled with k-ε turbulent model and the particle phase was modeled with kinetic theory of granular flow

This book provides practicing engineers and students with insight into the design and operation of circulating fluidized bed boilers through a combination of theoretical concepts and practical instruction. Numerous examples from actual operating plants illustrate key concepts in combustion, hydrodynamics, heat transfer, and materials.

In a bubbling fluidized bed, the fuel fed from either the top or the sides mixes relatively fast over the whole body of the fluid bed (Figure 5.7). The gasifying medium (air, oxygen, steam, or their mixture) also serves as the fluidizing gas and so is sent through the bottom of the reactor.

In the 2nd Generation PFB plant coal is partially gasified in a pressurized fluidized bed reactor to produce a coal derived syngas and a char residue. The syngas fuels the gas turbine and the char fuels a pressurized circulating fluidized bed (PCFB) boiler that powers the steam turbine and supplies hot vitiated air for the combustion of the syngas.

The bed of solid particles exhibits the properties of a boiling liquid and assumes the appearance of a fluid "bubbling fluidized bed". At higher velocities, bubbles disappear, and particles are blown out of the bed. Therefore, some amounts of particles have to be recirculated to maintain a stable system "circulating fluidized bed".
