Australian subbituminous coal loaded with the single and mixed catalysts of the alkali and transition metal salts [K 2 CO 3 , Ni(NO 3 ) 2 , K 2 SO 4 , Ni(NO 3 ) 2 +K 2 SO 4 ] was gasiยฎed in an internally circulating ยฏuidized bed (0.3 m-I.D. ร 2.7 m-high) with a draft tube (0.1 m-ID ร 0.9 m-high) at
Ahatract--In order to study the role of particles in augmenting heat transfer from the wall of a circulating fluidized bed (CFB), simultaneous heat and mass transfer experiments were carried out. For heat transfer, particles are important hydrodynamically, augmenting gas convection, and are a source
An inviscid model is developed to describe gross solid circulation and gas backmixing in axisymmetric fluidized beds. Two distinct cases arc shown to arise: (1) interstitial gas moves upwards everywhere; and (2) interstitial gas circulates giving rise to loop formation in an annular region near th
