Practical primer on design of electric arc furnace emission control systems
- Hatch Associates Ltd., Mississauga, Ontario (Canada)
The paper will cover the methodology for designing environmentally acceptable and cost-effective emission control systems in modern electric arc furnace meltshops. Fundamental requirements for effective direct evacuation control (DEC) of electric and ladle furnace melting operations and canopy/local hood control of secondary emissions from electric arc furnace charging and tapping emissions will be addressed. The following topics will be included: considerations in selecting appropriate DEC exhaust rates for effective emission control; water-cooled elbow, combustion gap and water-cooled duct design for maximizing post combustion and minimizing slag deposit build-up; off-gas cooling; deep storage-type canopy hood design for electric arc furnace charging emission control; local hood design for control of EBT emissions; furnace enclosures for improved secondary fume control and meltshop environment; off-gas system control philosophy; selecting appropriate equipment such as baghouses, fans and material handling systems; and common shortcomings of fume control systems. Emphasis will be on practical design aspects of meltshop emission control systems with guidelines on typical gas flow rates, system configuration, sizing and costs for effective fume control. The objective is to provide steelmakers with a practical guide toward improved electric arc furnace meltshop emission control system design.
