Novolipetsk Metallurgical Combine has begun reconstruction of the hot air heaters of blast furnace No. 4 with a capacity of 2.1 million tons of pig iron per year. The project will reduce carbon monoxide (CO) emissions by 98% at this source and by 3.5% of the gross emissions of the entire plant.
Environmental modernization will be carried out without shutting down the blast furnace. Within the framework of the project in the period 2022-2024. three air heaters will be replaced one by one - this is equipment that allows to reduce fuel consumption for pig iron production by heating and supplying oxygen-enriched air to the blast furnace. The design features of the new stoves and an improved fuel gas afterburning system will ensure the environmental performance of production at the level of the best available technologies.
This project is a new stage in improving the environmental friendliness of the furnace after the completion of a major overhaul earlier this year. Thanks to the modernization, the furnace is equipped with dust and gas collection systems with a purification degree of 99.9%. All filtered dust is returned to production in the form of iron-containing raw materials for smelting pig iron, and the purified blast furnace gas is used as a secondary energy source.
Investments in the complex of projects for the reconstruction of air heaters will amount to more than 6 billion rubles.
