The result of the project is a demonstration technology that has a positive impact on the environment through a cleaner production process of iron iron with simultaneous energy recovery of blast furnace gas pressure. As a result, there will be a solution leading to: first of all: reduce the volume of waste generated in the form of sludge, and secondly: increase the energy efficiency of the blast furnace process. In order to increase the efficiency of dust removal ArcelorMittal Poland S.A intends to use a modern cyclone to replace the static dust collector with approx. 85 % (I degree of purification) and scribe for cleaning of blast furnace gas with a 10 % reduction in water consumption (II degree of purification) and reduced noise emissions. This system will be applied for the first time in national blast furnaces. The project will result in: — increase the efficiency of dry dedusting from 50 % (static duster) to 85 % (cyclone) – reduction of sludge by 70 % – reduction of water necessary for wet gas cleaning by 10 % – development of excess steam during the summer season (May to October): 10 tonnes per hour – eliminating the source of noise emissions up to 96 dB – choking group – raising the target gas temperature at the outlet of the treatment plant by 10 °C – increase the power generated in the turbine by 330 kW.
