Russian steel maker Novolipetsk Iron & Steel Works has started hot testing of new environmental protection equipment in steelmaking. Installation for cleaning gases from dust with a capacity of 600 thousand cubic meters of gas per hour will reduce dust emissions by five times at the mixer section of converter shop No 1. The mixing department is designed for processing molten iron coming from the blast furnaces of the plant. The metal is averaged in terms of temperature and chemical composition, after which it is transferred to the steel smelting section. During the pouring and draining operations, dust is emitted, which is captured and cleaned by the aspiration system.The new set of equipment includes an aspiration unit with modern bag filters, smoke exhausters and special trapping umbrellas over the places of cast iron overflow. The system allows increasing the efficiency of gas purification up to 5 mg of dust per cubic meter, which corresponds to the level of the best available technologies. The project is the next stage in the implementation of a quadripartite agreement on cooperation in the field of environmental development until 2024 between NLMK, the Russian Ministry of Natural Resources, Rosprirodnadzor and the administration of the Lipetsk region. Of the nine planned activities, NLMK has already implemented six projects.
