Domain production
The most powerful technological repartition of metallurgy is blast-furnace production. The blast furnace itself, the foundry yard and the charge yard are quite serious sources of dust emissions into the atmosphere. Our company has excellent references for all these sources and is ready to offer partners to make blast furnace production completely environmentally friendly.
Despite the gradual transition to coke-free metallurgy, blast furnaces, as pig iron smelting units, will be in operation for a long time. There are three main sources of harmful emissions in blast furnace production. The first source is the foundry. Dust is emitted from it during the discharge of cast iron and slag from the furnace. The direct points of dust emission are cast-iron and slag chutes, tapholes and places of installation and filling of cast-iron ladles. Our standard project provides for the shelter of all places of dusting and the evacuation of dusty air with further purification in a bag filter. Similarly, dusty air is removed from the dusting points in the under-bunker rooms (feeders, conveyors, dispensers, screens, etc.) and also cleaned in a bag filter.
We have also developed a unique system for dry cleaning of blast-furnace gases in a bag filter, which has a huge environmental and economic effect. We already have references for such installations, the practical payback period of which is no more than 1.5 years.
