Solids Flux, Velocity And Local Solid Fraction Measurements In A Cfb Riser, Ronald W. Breault, Christopher Guenther
Solids Flux, Velocity And Local Solid Fraction Measurements In A Cfb Riser, Ronald W. Breault, Christopher Guenther
The 12th International Conference on Fluidization - New Horizons in Fluidization Engineering
In this investigation a fiber-optic probe and an extraction solids probe are used to measure particle velocities and solids flux values. These are subsequently used to determine the local solids fractions as a function of radial position in a cold flow circulating fluidized bed (CFCFB) in operation at the National Energy Technology Laboratory (NETL). Measurements were taken under several separate operating conditions ranging from dilute up-flow to core-annular flow to fast fluidization using nominal 800 micron cork particles. The solids properties and test operating conditions were chosen particularly to provide dynamic similitude between the test data and the operation of …
