摘要: Abstract High temperature heat transfer data in the particle diameter range 0.73 – 1.41 mm and 490 918 °C are presented. The original measurement method is based on an overall thermal balance over a 0.40 m 2 exchange surface. Experimental analyzed using results from literature ‘particle-based’ model. It found that gas convective significant for largest particles (1.41 mm) but it may be neglected 1.18 at temperatures above 700 °C. An analysis of this result basis Saxena Ganzha's powder classification scheme proposed. A general correlation Archimedes Planck numbers takes into account interaction between radiation conduction high temperatures, utilizing experimental beds corundum (0.28, 0.425, 0.6, 0.73, 1, 500 900
