Sinter Plant
High performance combined with environmental friendly solutions
With more than 5 decades on sintering technology Siemens VAI offers a full portfolio of solutions and services which ranges from the highest competence in designing
New Sinter Plants - among the most demanding markets and customers - to customized full optimized
Modernization Packages.

Sinter Plant Modernizations: the cheapest way to grow!
Using our sinter technologies, also available through tailored modernization packages, plant operators can increase capacity of sinter machine and cooler, enhance sinter quality and consequently reduce solid-fuel and electric energy consumptions and increase productivity in the blast furnaces.
The Best Raw Mix Preparation
The Siemens VAI Intensive Mixing and Granulation System improves homogeneity of the sinter raw mix and allows fine and ultrafine ores, concentrates and revert material to be economically sintered.
This results in a better sinter bed permeability, a more equalized burn through zone and reduced energy consumption which consequently improves the overall productivity.
Furthermore the sinter mix preparation allows to eliminate blending yards and, thus, drastically reduces the area requirements and investment costs for a sinter plant due to storage reduction.
Charging Concept
The newly developed Twin-layer Charging System charges the sinter raw mix to the sinter machine by segregation in two layers with different average grain size. The top layer consists of smaller average grain size and a higher concentration of coke resulting in excellent ignition behaviour whereas the bottom layer ensures high permeability and efficient use of solid fuel.
Sinter Machine Capacity Increase
With the new generation of sinter machines, the so-called
Grate Wing Pallet Cars, it is possible to increase the capacity of the sinter machine by up to 12%.
Alongside it is possible to decrease the off-gas volume with the installation of
rim-zone covers, which reduce the
false air sucked along the side walls of
conventional sinter machines.
Cooler Design and Energy Recovery Systems
The new sinter cooler design featuring the Grate Wings Cooler Troughs permits a higher cooling efficiency resulting in decreased specific cooling air volume and subsequently decreased specific electric energy consumption, and thus lower investment and operation costs. The new design can also be applied to an existing cooler, increasing the capacity by approximately 15%, without the need to increase the cooling air volume.
The advanced design of the Cooler Charging Chute ensures a more homogeneous distribution of the sinter onto the sinter cooler, keeping the larger diameters near the bottom and the smaller at the top. This increases the cooling performance, reduces fan power consumption and prevents damage to subsequent equipment.
To further improve the energy efficiency of the sinter plant we offer different types of Heat Recovery Systems, which can be installed at the sinter cooler or in the waste gas system of the sinter machine, where the sensible heat of the off-air is used to generate an interesting amount of electric energy or process steam.
Environmental and Energy Compliance
A typical sinter plant configuration today with conventional blowers and electrostatic precipitators may not meet the latest environmental regulations, which call for a higher dust and pollutants removal (e.g. SOx, NOx, dioxins).
Therefore the Selective Waste Gas Recirculation System has been developed by Siemens VAI. The target is to re-circulate part of the off-gas from especially selected wind-boxes in the area of interest back to the sinter process and use the positive effects of filtration and post combustion in the bed layer (recirculation of combustible components, pollutants, aerosols).
Specific investment costs are paid back due to the provided savings and additional equipment for gas cleaning facilities are optimized in terms of investments and operational costs. The typical benefits of such a system is the reduction of the total off-gas volume by up to 40 percent and reduction of the coke consumption and CO2 emissions by up to 10% each.
Sinter Expert Services
Siemens VAI offers a wide range of services to help our customers keep up with the global challenges facing the ironmaking industry today. Beginning with operational consultation and plant assessment we enable our customers to maintain a high productivity at the lowest possible costs.
We also offer operational and preventive maintenance advisory services and provide valuable support to customers during start-up and shut-down periods. To ensure expert process know-how trainings on-the job and off-site is available. Furthermore research and analysis services as well as raw material tests complement our services portfolio.
Residuals Utilization at Sinter Plants
Siemens VAI´s approach considers increasing the input of recycling materials into sinter plants as a proven economical route for in-plant by-products (dusts, sludge, scales, etc) of integrated steel works. Resulting effects on sinter quality, emissions and gas cleaning facilities will be taken into consideration as well. Emission limits of the sinter waste gas and quality parameters of the produced sinter are the two most important limiting factors.
Usually the benefits of such a procedure are the reuse of waste materials which are normally rich in iron, flux and fuel value. Therefore it is possible to generate savings in disposal cost and also by the replacement of raw materials. Investment costs for residuals utilization are lowered if an existing sinter plant is used.
The SIMETAL Sinter VAiron automation expert system controls the process in order to obtain sinter with excellent stable chemical and physical properties while maintaining or improving high productivity, low fuel consumption and fulfilling environmental regulations. To achieve these goals the expert system analyzes data from charged and produced material as well as process data from the sinter plant, storage and blending yards and proposes the best operating strategies.
MEROS® - Maximized Emission Reduction Of Sintering
Siemens VAI developed the MEROS® process in order to further reduce specific emissions to within the municipally prescribed values. MEROS® is capable of lowering dust, acid gases and harmful metallic and organic components present in the sinter off gas to concentrations previously unattained with conventional gas-treatment techniques. With the Siemens VAI MEROS® technology polluting emissions can be reduced to meet environmental regulations with reasonable investment and operational costs. The MEROS® process is characterized by a series of treatment steps in which dust and pollutants still present in the sinter off gas after the primary dedusting step (e.g. electrostatic precipitator or cyclone type) are further reduced in a series of process steps.
Before and after MEROS® Start-up voestalpine Stahl, Austria
In order to enhance the gas-cleaning efficiency and to significantly reduce additive costs, the separated dust particles are recycled to the off gas stream after the conditioning reactor. A portion of this dust is removed from the system and conveyed to intermediate storage silos for subsequent use in environmentally friendly applications. Dust emissions are reduced in the MEROS® process to <5 mg/Nm3 in the clean gas and heavy-metal emissions by more than 95%. Organic compounds are virtually eliminated and SO2 emissions are also considerably reduced, controllable by reagents addition.
Siemens VAI products and solutions for the sinter technology ultimately increase plant performance in a quantifiable and sustainable way. For us the challenge starts from your plant needs.
