Digital image analysis of bubble flow – influence of operational parameters
Paper in proceedings, 2010

In a first step towards investigating the horizontal fuel mixing in fluidized bed (FB) boilers, this work applies digital image analysis to study the bubble flow properties in a 2-dimensional FB unit. The work investigates the influence of fluidization velocity, bed height and gas-distributor pressure drop on the volume fraction and horizontal distribution of bubbles.
