Abstract. The paper presents theoretical knowledge and practical experiences from the experiment on heat transfer between immersed heat transfer surfaces and circulating fluidized bed (CFB). Both theory and experiments agree that heat transfer coefficient is strongly dependent on hydrodynamics of the bed, i.e. on the bed voidage, which is the most important hydrodynamic factor. 
UTICAJ POROZNOSTI SLOJA NA RAZMENU TOPLOTE
IZMEĐU URONJENIH IZMENJIVAČKIH POVRŠINA I CIRKULACIONOG FLUIDIZOVANOG SLOJA
U radu su prikazana teorijska saznanja i rezultati realnog eksperimenta o razmeni toplote između uronjenih izmenjivačkih površina i cirkulacionog fluidizovanog sloja (CFB).
