Abstract
Primary and secondary gas-duct emissions characteristics: composition, amount, temperature, physical, and chemical heat content (enthalpy). Systems for both capturing and preliminary preparing of emissions to their cleaning in bag filters. The reasons resulting in the fact that an amount of gases cleaned in bag filters exceeds 70 and even more times that of primary dust-loaded gases generated in EAF’s freeboard. Some ways of reducing unjustified high electrical energy consumption related to gas evacuation. The problems of high toxic emissions: CO, dioxins, etc.
Simplified techniques for calculations of gas parameters of the direct evacuation system: carrying capacity of the system, hydraulic resistance of its elements; examples of calculations.
Air curtains for eliminating air infiltration into a furnace slag door: theoretical grounds, calculation methods, design features.
