Figure 1 shows a simplified diagram of a sinter plant. Materials enter the sinter plant from storage bins. They are mixed in the correct proportions using weigh hoppers, one per storage bin, except for the return fines for which an impact meter is used instead. Weighing is continuous, as is the whole sintering process.

In coal, lead is mainly associated with organic compounds. It volatilizes at approximately 850°C in the form of PbO (g).Between 730°C and 820°C, it can be transformed into PbO (s) and below 730°C, solid lead sulphate is formed. The presence of chlorine can result in the Pb remaining in the form of vapor (Zhao et al., 2018).On the …

Abstract. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described to identify the key steps of the process, that is, granulation and thermal densification. Discussion is then focused on the effect of the chemical, physical ...

This reduces off-gas volumes by about 40–50% without affecting the sintering process. In an emission optimized sintering plant, the whole sintering gases are collected and then forced to recirculate on the sintering surface to contribute to the material heating (Fig. 3.18). In this way <50% of the waste gas is emitted in the atmosphere.
