Filtrabit’s flow-dynamic filter is installed inside the 15-metre-high filtration unit of the coking plant, where a traditional textile filter can reduce only part of all the microparticles below 2.5 micrometres in diameter.
The SSAB steelworks in Raahe, together with subcontractors, employs more than 4 000 people and uses over a million tons of coal per year.
Filtrabit’s flow-dynamic filter is installed inside the 15-metre-high filtration unit of the coking plant, where a traditional textile filter can reduce only part of all the microparticles below 2.5 micrometres in diameter.
Air flows through the flow-dynamic filter at a rate of 2 400 cubic meters per hour. From the air, up to 100 kilograms of coal dust per hour is separated directly into a container. Most of the dust collected is in the sub-2.5 micrometre range, that is especially harmful to breathe.
The flow-dynamic filter has markedly improved the working conditions of process workers at the filtration unit.
The system has been in use since 2020 and has not had a single instance of clogging.
