The transfer of heat from a stationary granular bed (packing) to a gas-particle flow has been investigated experimentally. Heat transfer experiments were carried out on an apparatus with an open gas-particle flow system. Monodisperse packing comprised of smooth steel balls or round porcelain granules was used. Particles used in the gas flow consisted of grades of sand and electrical corundum. The external heat transfer coefficient was determined by local modeling of heat transfer in the steady temperature field regime. Calorimetry was used for determining this regime as well as the temperature of the air and dusty gas. A correlation was obtained for calculating the heat-transfer coefficient in the system.
