The report gives results of a laboratory study to develop basic information on the emission of organics from iron ore sinter beds. Samples of sinter bed mix components (including several types of iron ore fines, blast furnace flue dust, rolling mill scale, anthracite coal, and limestone) were obtained from three sinter producers. Small samples were heated in a tube furnace under a 100 m1/m in flow of N2 or air. A combination of total organic analysis and full chromatographic analysis was used to determine the rate of organic emissions as a function of temperature and to characterize the nature of the emissions. Maximum emissions were observed between 300 and 500C. Substantial emissions occurred as low as 100C and as high as 800C. They were less in air than in N2, indicating that combustion occurred even at comparatively low temperatures where the fixed carbon does not burn. Mill scale and blast furnace dust were shown to be the major sources of the organic emissions. These results suggest procedures for recycling the hydrocarbon-bearing gases through the hot sinter bed to produce complete combustion and for thermally pretreating the offending components.
