13. Assessment of the Potential Implementation of Solar Energy Generation in State Schools in Curitiba/PR
ABSTRACT Solar energy as a form of electric power generation is gaining ground in Brazil, being the subject of worldwide discussions on sustainability. The electric energy, a right of all citizens, represents a consumption of natural resources on a large scale. State schools in Paraná invested more than R$ 46 million to guarantee electricity and thus provid

15. Analysis of the Impacts of the Electrification of the Vehicle Fleet in the Electric Power System in Curitiba
ABSTRACT The Market share of electrical vehicles has been rising in the past few years and tends to rise even more. According to the International Energy Agency, an increase of 50% in the number of electrical vehicles is expected. Whilst that increase is beneficial from a greenhouse gases emissions drop point of view, that rise could, on the other hand, repr

16. Electroremediation of deactivated catalysts from fluidised catalytic cracking for vanadium removal - the effect of a dual cathode chamber reactor
Abstract The aim of this study was to evaluate the quantity of vanadium removed through electrokinetic remediation applied to catalyst waste used in a fluid catalytic cracking process. In excess, vanadium affects process efficiency by reducing the catalyst’s activity, causing deactivation and reducing its useful life in petroleum cracking during refining.

17. Study of the electricity consumption reduction of a compressed air system: the case of a steelmaking company
Abstract This work aims to reduce the energy consumption and thus increase the availability of blast furnace compressors of a steelmaking company, located in Alto Paraopeba region in Minas Gerais state, Brazil, through the elimination of waste points in the compressed air distribution. In order to develop this work, an ultrasound test in the compressed air l

18. MgO Saturation Analisys of CaO-SiO2-FeO-MgO-Al2O3 Slag System
Electric arc furnace (EAF) slag has a range of functions, including improving energy efficiency through the "slag foaming" phenomenon. As such, the study of slag is important in EAFs. One of the factors that determine foaming quality and efficiency is the presence of solid particles. MgO saturation is highly significant since, in addition to ensuring the pre

19. SPACIAL ILLUMINANCES VARIABILITY AND ENERGY CONSUMPTION IN AVIARIES FOR LAYING HENS EQUIPED WITH COMPACT FLUORESCENT LAMPS AND LIGHT EMITTING DIODE
ABSTRACT The spatial illuminance distribution interferes in the commercial production of eggs and electric energy consumption, being considered the second major source of costs in the production chain. Therefore, in this study the objective was to evaluate the spatial distribution of the illuminance level and electric energy consumption in two commercial avi

20. Slag Evaluation to Reduce Energy Consumption and EAF Electrical Instability
In steel mills that operate with electric arc furnaces (EAF), it is interesting to ensure greater stability to the electric arc to aim at less distortion in the electrical system, with consequent reduction in electric power consumption. The slag foaming increases electric arc stability by reducing the total harmonic distortion (THD) between EAF phases. In th

21. MicrogeraÃÃo de energia elÃtrica com gÃs de sÃntese de um gaseificador concorrente utilizando ItaÃba mazilaurus / Microgeneration of electricity with syngas from a downtraft gasifier using ItaÃba mazilaurus
The use of biomass as energy source is one of the most promising, because it contributes to reduce emissions of carbon dioxide in the atmosphere and allow the decentralized energy generation. Gasification is a technology of processing biomass energy into a gaseous biofuel of low calorific value. The gas can be used in Otto cycle engine for power generation i

22. THE DEMAND FOR RESIDENTIAL ELECTRICITY IN BRAZIL: 2011-2020 / A DEMANDA POR ENERGIA ELÉTRICA RESIDENCIAL NO BRASIL: 2011-2020
This work aims to quantify the relations between the electricity demand and some of its determinants in the Residential sector of Brazil. To begin with a short discussion is carried out on the Residential energy consumption in the country throughout the last four decades so as to get to know the residential consumption within a wider context. After, we adopt

23. Aplicação de redes inteligentes nas instalações elétricas residenciais / Application of smart grid in residential electrical installations.
Electricity as an energy resource acquired vital importance in modern society because it allows relatively easily meet the demand for their services. Thus the demand for electricity increases with the evolution of populations who benefit from. The electrical system that produces this input is limited in its ability to available resources for generation, tran
