The coke breeze has high fixed carbon content (83.37 wt.%) and low volatile matter content (1.57 wt.%). 2.2 Methods. The double-layer sintering process is …

Iron ore sintering is known as an important source of organic pollutants, such as PCDD/Fs ... The most common equipment for treating flue gas from sintering plants is ESP. This equipment works by generating an electrostatic field in the dust path. A voltage of thousands of volts is applied ionizing the gas around the electrodes.

Thermo Fisher Scientific offers advanced systems and equipment for all aspects of iron and steel manufacturing, particularly for measuring and controlling sintering process fluctuations, inhomogeneous mixtures, and other parameters that affect productivity, physical and metallurgical quality, and raw material consumption and costs.

For the ferrous burden of blast furnaces in China, sinter generally accounts for more than 70% and the sintering process accounts for approximately 6–10% of the total energy consumption of the iron and steel enterprise. Therefore, saving energy during the sintering process is important to reduce the energy consumption in the iron and steel …

The iron ore sintering process is the main source of VOCs emission in the iron and steel industry, and its VOCs emission accounts for about 69.6% . The organic compounds in the solid fuel and the oil components from the raw materials such as rolling oily sludge are pyrolyzed in the preheating layer (150–900 °C) to produce VOCs [ 9, 10 ].

The sintering process can be defined as a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke) with the objective of obtaining a product with the suitable characteristics (thermal, mechanical, physical, and chemical) to be fed to the …
