Abstract
During copper smelting, copper concentrates containing organic carbon compounds are subjected to the roasting process in a fluidised-bed furnace. The roasted concentrate formed in the process contains substances which deposit on the surfaces of the tubes present inside the furnace. The deposits contribute to the reduction of the heat flux absorbed from the bed. This study investigates the morphology, chemical composition and thermophysical properties of the deposits. The impact of the increase in the deposit thickness on the increase in the deposit surface temperature and the reduction of the heat flux absorbed by water was determined. A deposit taken from an industrial facility was analysed. It was established that, for a deposit with a thickness of 40 mm, there was an approximately 80 % decline in the absorbed energy as compared to a clean tube surface.
期刊介绍：
International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
