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.
