Abstract

It has been observed under certain flow conditions that there is a measured increase in fine particle concentration at the center of the circulating fluidized bed riser just below the exit to the cyclone. It is hypothesized that the Saffman force might be responsible for this phenomena. Furthermore, this research paper discusses the likelihood of the existence of “Saffman” forces, or lift due to viscous shear, in cylindrical, circulating fluidized bed (CFB) risers operating in the core annular regime.

Pressure and apparent voidage profiles for riser with an abrupt exit (T-shape) in a CFB riser operating above fast fluidization regimes

Journal Article Monazam, Esmail R. ; Breault, Ronald W. ; Shadle, Lawrence J. - Powder Technology

The influence of abrupt exit (T-shaped) configuration on the riser axial pressure profile in a large-scale circulating fluidized bed (CFB) is examined. A new analysis was developed to predict the axial voidage along the length of influence in the exit region with T-shape geometry. The exit region was characterized using non-dimensional analysis of the continuum equations (balances of masses and momenta) that described multiphase flows. In addition to deceleration length due to abrupt exit, the boundary condition for the solid fraction at the top of the riser and the fully developed regions, were measured using an industrial scale circulating fluidizedmore »« less

Investigation of core-annular flow in an industrial scale circulating fluidized bed riser with electrical capacitance volume tomography (ECVT)

Journal Article Weber, Justin M. ; Bobek, Michael M. ; Breault, Ronald W. ; ... - Powder Technology

There is a paucity of riser data for industrial scale units, particularly with regard to the solids fraction. This is especially true for detailed spatially distributed values. To alleviate this problem, NETL installed a 0.445 m tall electrical capacitance volume tomography (ECVT) sensor 9.66 m from the gas distributor of its industrial size (15.45 m high and 0.3 m diameter) circulating fluidized bed (CFB) cold model. A series of tests were conducted to investigate the gas-solid flow behavior using high density polyethylene (PPE) solids. Static electricity was successfully minimized using Larostat and humidification. Time averaged radial solid fractions profiles aremore »« less

Flow Regime Study in a High Density Circulating Fluidized Bed Riser with an Abrupt Exit

Conference Mei, J S ; Shadle, L J ; Yue, P C ; ...

Flow regime study was conducted in a 0.3 m diameter, 15.5 m height circulating fluidized bed (CFB) riser with an abrupt exit at the National Energy Technology Laboratory of the U.S. Department of Energy. Local particle velocities were measured at various radial positions and riser heights using an optical fiber probe. On-line measurement of solid circulating rate was continuously recorded by the Spiral. Glass beads of mean diameter 61 μm and particle density of 2,500 kg/m3 were used as bed material. The CFB riser was operated at various superficial gas velocities ranging from 3 to 7.6 m/s and solid massmore »« less

Flow Regime Study in a Circulating Fluidized Bed Riser with an Abrupt Exit: [1] High Density Suspension

Conference Mei, J S ; Lee, G T ; Seachman, S M ; ...

Flow regime study was conducted in a 0.3 m diameter, 15.5 m tall circulating fluidized bed (CFB) riser with an abrupt exit at the National Energy Technology Laboratory of the U. S. Department of Energy. A statistical designed test series was conducted including four (4) operating set points and a duplicated center point (therefore a total of 6 operating set points). Glass beads of mean diameter 200 μm and particle density of 2,430 kg/m3 were used as bed material. The CFB riser was operated at various superficial gas velocities ranging from 5.6 to 7.6 m/s and solid mass flux frommore »« less
Solids flow pattern in the exit region of a CFB -- Furnace influence of exit geometry

Conference Johnsson, F ; Leckner, B ; Vrager, A

The effect of the exit geometry on the flow pattern in a circulating fluidized bed (CFB) riser was studied in a cold 1/9 scale model of the Chalmers 12 MW CFB boiler. The model, which is made of transparent perspex, was operated according to the simplified scaling laws proposed by Glicksman et al. (1993). 12 different exit configurations were compared at different fluidization velocities. Two bed materials were used: iron and steel. In order to verify the scaling laws, vertical pressure and density profiles, net solids flux and pressure fluctuations measured in the model were compared with corresponding results frommore »« less
