This paper aims to analyze the information about protection of technologies related to distributed generation (DG) of electric energy, available in the Brazilian patent bank, in the period between 2011 and 2020. Considering that the energy sector has strategic role for companies and countries, analyzing technological trends in the area can help management and decision making. As a methodological procedure, (1) data were collected from the national database of the Instituto Nacional de Propriedade Industrial - INPI (National Institute of Industrial Property) -- in July 2020, (2) associated with keywords and the Classificação Internacional de Patentes - IPC (International Patent Classification) for research and (3) treated with the aid of Microsoft Excel and IBM SPSS Statistics version 25 software. The variables found and analyzed were: nature of the patent; order status; international classification; year of filing; publication of request; countries of origin of depositors; main depositors; state of origin of depositors; electrical system structure; and types of energy sources. The results demonstrated that the number of patent filings fluctuated over the years; that there was a significant growth in the number of deposits in the years that normative resolution n° 482/2012, responsible for regularizing DG in Brazil, was published or revised and that most of the technologies deposited are intended for power generation, with emphasis on that use wind energy.

This paper presents the history of actions taken byArcelorMittal Monlevade that contributed to the blast furnace A reaching the national record of use of small coke in the fuel rate in 2008. In parallel, the reduction of the total consumption of metallurgical coke has achieved one of the best values in the national steel industry. This study was evaluated using an analysis of the beginning of operations of the blast furnace A, using low level of small coke in the fuel rate, associated with a coke + small coke balance in the Monlevade plant and with the actions of the control process developed over the time. The results showed a higher consumption of small coke in the charge, decreasing consumption of a coarse metallurgical coke and a better working stability of the blast furnace A. These results lead in productivity increasing and reducing the coke rate of the blast furnace A in the recent years. [ABSTRACT FROM AUTHOR]

This paper describes the latest big Consteel® applications around the world and the perspectives of utilization of this recognized technology on the recovery of the growth of the Brazilian Steel Industry, with particular attention to the utilization of hot metal as main part of the charging mix. The Consteel® EAF process represents the extension of the advantages of continuous charge feeding and melting process - typical of EAFs charged with 100% DRI - to the charging of scrap. This with the additional benefit of an "environmentally friendly" preheating of the charge help the reducing energy requirements of the process. Moreover the possibility of injecting oxygen for 100% of the power-on time makes the Consteel® process the best option for taking most of the advantages coming from hot metal charging in an EAF. Process details and technological peculiarities of this particular type of operation are described. [ABSTRACT FROM AUTHOR]
