Ecological elements of the electric arc furnace

The Electric Arc Furnaces (EM) for making steels, as powerful energy aggregates, are naturally important polluting agents. The paper presents a theoretical and experimental analysis of the polluting generating mechanisms for steel making in the EAF. The scheme for the environment's polluting system through the EAF is designed and presented in this paper. The ecological experimenting consisted of determining by specialized measures of the dust percentage in the evacuated gases front the EAT and of there of gas pollutants. From the point of view of reducing the impact on the environment, the main problem of the electric arc furnace (EAF) is the optimization of the powder collecting from the process gases, both from the furnace and from the work area. This optimization is both for the work conditions improvement and for the following of the limits imposed by the work and environment protection legislation. The paper deals with the best dependence between the aggregate's constructive, functional and technological factors, which are necessary for the furnace's ecologization and for its energetically-technologically performances increasing.
