Abstract
The DANARC electric arc furnace technology combines high-impedance technology with bottom tuyeres for oxygen and carbon injection. Together with lance injection and wall burners for both conventional operation and post-combustion, the DANARC concept provides full flexibility in the choice of energy sources. The basic philosophy with the DANARC concept is to have efficient systems for the supply of both electrical and alternative energy. Operation results from the DANARC furnace at Ferriere Nord, Italy, show that it is possible to inject high specific amounts of oxygen and carbon as a substitute for electrical energy. The electrical power supply with a fixed or saturable reactor is beneficial due to the high voltage and low current operation. High-impedance operation gives a low electrode consumption, reduced electrical losses and a reduction of the supply network disturbances, i.e. flicker.
