Deposits formed on heat exchangers in directly fired thermoprocessing plants impair their operation. Experiments and analysis of the deposits were performed to examine their origin and impact in steel treatment furnaces. Experimental volatilization rates were obtained for chromium and molybdenum and in the case of chromium, rates were also calculated. For the calculations, knowledge of the structure of oxide scale on the steel is required. By reproducing the deposits in a burner rig, recommendations were derived concerning prevention and removal of deposits.
