Abstract
In method for enhancing heat transfer in a bed of powder comprising cohesive Geldart type C particles confined by a wall of a vertically oriented container and being fluidized by the upward flow of fluidizing gas through the bed of powder, heat is transferred between the bed of powder and the wall of the container, and, prior to fluidizing the particles, the fluidizing gas is selected so as to comprise a sufficient amount of helium, hydrogen, or mixtures thereof for obtaining a thermal conductivity of the fluidizing gas of at least four times that of nitrogen for enhancing heat transfer between the wall and the bed.
