Dedusting technologies
We install the world’s most advanced technologies at our operations. In the steel sector these are bag filters which collect even the finest dust particles including benzo(a)pyren and dioxins. The EU mentions them as the best solution and considers them the best available technique (BAT).
The exhaust gas from operations is sucked off into the bag filter where it goes through tens of thousands fabric hoses which collect dust particles of all sizes. Dusted hoses are cleaned up on a regular basis by means of an air stream and the blown-out dust is transferred into a silo. Thus, the smoke rid of dust particles comes out of the chimney.
In 2015 several bag filters were installed at the mill. The most significant one of them is the bag filter for two sintering belts at the sinter plant south. The filter worth of 365 million CZK collects nearly 100 tons of dust a year! The remaining three sintering belts at sinter plant north have been de-dusted by a bag filter since 2011. It cost 1 billion CZK and reduced dust emissions by 270 tons a year.
