Making an oxygen steel factory (Basic Oxygen Furnace - BOF) more efficient focuses on maximizing energy recovery, optimizing the oxygen blow process, reducing fossil fuel reliance, and enhancing material recycling. Modern advancements allow for significant reductions in carbon footprint and operational costs. The BOF is highly energy-efficient in terms of process heat, consuming only about 1.2 GJ per tonne of crude steel, as it relies on the exothermic oxidation of impurities in hot metal. While the overall BF-BOF...

The basic argument of the present study lies in the request of the agency of the Danube Delta Biosphere regarding the regulation of travel speeds of different types of boats. One among the cases of analysis was the one that refers to a patrol vessel. The purpose of this paper aims to follow the creation and study of the displacement of a ship of maritime patrol produced by the Damen company, inside the Danube Delta on 3 channels of different sizes. To carry out this work, the patrol vessel named "Stan Patrol" it w...

The Danube Delta dynamics formation and expansion represent the motivation of the study included in this paper. The results of soil studies made possible to develop the Danube Delta genesis maps [7]. That informationпїЅs are the input data and the validation data for the numerical flow studies of the Danube River. The study of the formation of new territories has been developed by the Computational Fluid Dynamics (C.F.D.) method. There were modelled in three dimensions the maps for Danube River Basin flowing into ...
