3D fullloop simulation of an industrialscale ...

Aug 31 2012 · Threedimensional (3D) simulations using an Eulerian multiphase model were employed to explore flow behaviors in a fullloop industrialscale CFB boiler with and without fluidizedbed heat exchanger (FBHE) where three solids phases were employed to roughly represent the polydisperse behavior of particles.

Fluidized Bed Boiler - an overview | ScienceDirect Topics

Modeling of CFB boilers requires the pressure balance over the circulating loop to be closed since this determines the solids mass present in the downcomer from the cyclone which is of importance for the overall solids population balance. This balance can be expressed as in Eq. [11.40] (the letters AE are explained in Fig. 11.6).

Bed Inventory Overturn in a Circulating Fluid Bed Riser ...

The special phenomenon nominated as bed inventory overturn in circulating fluid bed (CFB) riser with pant-leg structure was studied with model calculation and experimental work. A compounded pressure drop mathematic model was developed and validated with the experimental data in a cold experimental test rig. The model calculation results agree well with the measured data. In addition the ...

Effect of Bed Pressure Drop on Performance of a CFB Boiler ...

For this boiler at the optimum point the bed pressure was around 5.7 kPa with the overall excess air ratio of 1.06. When the boiler was operated around this optimal point not only the combustion efficiency was improved but also fan energy consumption and wear of heating surface were reduced.
