OPTIMAL OPERATION OF ELECTRIC ARC FURNACES (EAF) TO MINIMIZE THE GENERATION OF AIR POLLUTANTS AT THE SOURCE
Description:
The manufacture of steel by electric arc furnaces (EAF) is continuing to
increase in usage in the United States with current production estimated to be
over 63 million tons per year. The reduction of emissions from steel producers
has been slow for two main reasons: the need to maintain or increase current
production levels and the lack of understanding and control of the steel-making
process.
The EAF holds a three-phase system of liquid (molten steel), slag (metal
oxides), and gas with both mass and heat transfer taking place amongst the
three. The furnace operations, or controls, include carbon injection, oxygen
lancing, burner operation, and air infiltration. The controls are used to
produce the appropriate grade of liquid steel at a requested temperature.

Approach
:We propose to develop a dynamic model of the electric arc furnace consisting of melting, equilibrium chemistry, and material balance sub-models. The EAF model will include all of the furnace operations involved in an industrial furnace. Preliminary investigations into the control of the furnace to minimize carbon monoxide emissions have shown that the system is extremely sensitive to carbon injection and burner oxygen controls. These results show great promise for the improvement of furnace performance, which includes environmental impact and energy consumption.
