Sinter plants are sink for solid wastes generated in a steel plant. All the dusts generated in the sinter plant are recycled back, and thus no solid waste or hazardous waste is generated. Wastewater is generated mostly in sinter plants where multi-cyclone are used for cleaning process gas (Li et al. 2019b ).

Suppose a sinter plant consumes coke breeze of ~50 kg/t.sinter, and the BF coke rate is around 500 kg/t.HM . The estimated gases generated from sinter plant are SOx ~35 % and NOx ~28 % of the total emissions in an integrated steelworks (Mou 1998 ).
The function of the Sinter Plant is to supply the blast furnaces with sinter, a combination of blended ores, fluxes and coke which is partially 'cooked' or sintered. In this form, the materials combine efficiently in the blast furnace and allow for more consistent and controllable iron manufacture. Figure 1 shows a simplified diagram of a ...

The feed is placed on a sintering bed, where thermal agglomeration (1300-1480 °C) takes place to produce clustered lumps, aka iron sinter (5-20 mm in size). At a common sinter plant, the following sinter quality parameters need to be controlled: Basicity, CaO/SiO2 – FeO (Fe2+) Sinter strength index, SSI. Tumbler index, TI.

Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an open-grained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.
It is evident from table 4 that the thermodynamic efficiency of the sinter plant calculated according to equation 7 is 45.1%. The product gases represent the principal exergy flow from the plant, 20 MJs −1; of this 92% is due to the SO 2 content. These gases pass to the Acid Plant.
