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.
