Model of an Electric Arc Furnace Oxy-Fuel Burner for dynamic simulations and optimisation purposes.

Optimization and dynamic studies of Electric Arc Furnances have long relied on empirical models to describe the behaviour of the oxy-fuel burner during the melting stages of a batch. These models are very week for optimization purposes as they fail to describe the effect that variations on both the scrap density and the flow rate of fuel have on the heat exchanges between the oxy-fuel flames and the solid scrap. In this work, we propose a novel first principles model that tackles those weaknesses and therefore,
can be used in dynamic optimisation approaches that aim at improving the efficiency or the economics of
the EAF. The well known empirical approximation by Bergman et al.,(1990) is used for validation purposes
and an average error lower to 3% is obtained over the whole batch time.
