Study of the cascade system model for waste heat recovery from the flue gases of the electric arc furnace

International Journal of Thermofluids
The paper deals with methods for recovering a significant part of the thermal energy consumed by the metallurgical industry and discarded as waste heat from the electric arc furnace. One of the main sources of heat removal from an electric arc furnace is

Potential of Organic Rankine Cycles (ORC) for waste heat recovery on an Electric Arc Furnace (EAF) [PDF]

, 2017
The organic Rankine cycle (ORC) is a mature technology to convert low temperature waste heat to electricity. While several energy intensive industries could benefit from the integration of an ORC, their adoption rate is rather low.

About the Possibility of Power Controlling in the Three-Phase Electric Arc Furnaces Using PSCAD EMTDC Simulation Program

Advances in Electrical and Computer Engineering, 2007
The electric arc is a nonlinear element. For this reason it must be used special techniques of modeling the electric arc that should reflect as closely as possible the behavior of the real electric arc.

Applications of thermal energy storage to process heat and waste heat recovery in the iron and steel industry [PDF]

The system identified operates from the primary arc furnace evacuation system as a heat source. Energy from the fume stream is stored as sensible energy in a solid medium (packed bed). A steam-driven turbine is arranged to generate power for peak shaving.
