Fluid Bed to Wall Heat transfer

[DrSmile]

Hello dear colleagues,

I am looking for data on bed to wall (and immersed surface) htc in fluidized beds of lime (and / or limestone) at Temperatures >500C. FB combustor data are typically the ones i'd need. Does anyone know where to look or at least a ballpark figure i can use to have a rough idea of the size?

Thanks everyone

Dr.
