Sinter Plant

High performance combined with environmental friendly solutions

 

 

 

Requirements for availability, product quality and productivity of sinter plants are continuously growing, and can only be met with rugged designs suitable for the harsh iron and steel making environment. At the same time, a growing number of environmental regulations necessitate extensive investment.
 

Siemens VAI, offering design solutions with integrated process knowledge, is a global full-line supplier, and our technologies meet local and market specific requirements.


With more than 5 decades on sintering technology Siemens VAI has successfully supplied, modernized and upgraded several sinter plants worldwide among the most demanding markets and customers.Our business is to reach more from ore.

Using our sinter technologies, also available thru tailored modernization packages, plant operators can increase sinter quality and consequently reduce coke consumption and increase productivity in blast furnaces.

The IMGS (Intensive Mixing and Granulation System) sinter mix preparation eliminates blending yards and thus drastically reduces the space requirements and consequently investment costs for a sinter plant. Also, sinter bed permeability and consequently productivity is improved with this system.

Our Twin Layer Charging, in combination with IMGS, even further increases plant productivity, also with increased bed heights.

 

With the Pallet Width Extension Technology and Selective Waste Gas Recirculation we offer solutions capable to reduce the off gas quantity in sinter plants up to 50%. This significantly lowers not only environmental pollution but power consumption as well.


Decision makers around the globe are always pursuing the best performance for their investments plans and with Siemens VAI Selective Waste Gas Recirculation technology we are able to decrease investment costs and also operational costs for waste gas cleaning plant.

Integrated automation and process control systems for the sinter technology lead to a maximized plant availability achieving full process transparency. Easy to train and easy to handle operating systems provide stable and reproducible sinter process conditions. With the Sinter VAiron the successful closed-loop expert system for blast furnaces has been adapted for the sinter process in order to obtain high productivity and low fuel consumption.

Sustainable solutions matching the most strict environmental regulations:

 

MEROS® (Maximized Emission Reduction Of Sintering)

 


MEROS, voestalpine Stahl, Linz, Austria:
The most environmentally friendly sinter plant in the world.


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 electrostatic precipitator are further reduced in a series of process steps.



 

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 <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.
