Análise técnica e econômica da utilização da energia solar e eólica em uma propriedade rural para geração de eletricidade, bombeamento e aquecimento de água

This paper is about a case study of using solar energy and wind energy in a farm. For this purpose were collected from the property, such as water consumption and amount of residents. So, we estimate how many conventional panels or PET bottle panels and boiler needed to supply the farm with warm water. It also calculates the amount of photovoltaic panels and the main accessories for converting solar energy into electrical energy. For the pumping of water using photovoltaic panels is dismissed and dimensioned to be a watermill

Implementação de um tuboexpansor na refinaria do Planalto Paulista – REPLAN com objetivo do aproveitamento da energia contida nos gases residuais do FCC – Fluid Catalytic Cracking na geração de energia elétrica

The steel type AISI 4130 (ultra-high strength steel) is an alloy of low carbon and its main alloying elements are chromium and molybdenum, which improves the toughness of the weld metal. It has numerous applications, especially where the need for high mechanical strength. It is widely used in equipment used by the aviation industry, such as cradle-tomotor, and this is the motivation for this study. Cots are of fundamental importance, because the engine supports and maintains balance in the fixed landing gear. This equipment is subjected to intense loading cycles, whose fractures caused by fatigue are constantly observed. Will be determined the effects caused by re-welding the structure of aeronautical equipment, and will also study the microstructure of the metal without welding. The studies will be done on materials used in aircraft, which was given to study. The results provide knowledge of microstructure to evaluate any type of fracture that maybe caused by fatigue. Fatigue is a major cause of aircraft accidents and incidents occurred, which makes the study of the microstructure of the metal, weld and re-solder the knowledge essential to the life of the material. The prevention and control of the process of fatigue in aircraft are critical, since the components are subjected to greater responsibility cyclic loading

Geração de energia elétrica a partir da concentração solar

The current world's need for clean and renewable energy sources aligned with the strong Brazilian growth looking to diversify its electric power generation sources, highly dependent on hydropower and petroleum encourages the implementation of technologies that reach this growth with diversity and cleaning. The sun energy source is considered inexhaustible and can meet the demand for energy through thermo solar plants to generate electricity. Several technologies are being studied and developed in the world and they can be used to generate electricity from the solar concentration, but in Brazil its use is still not found commercially. It is therefore essential to understand these technologies and develop knowledge about them so they can be implemented in Brazil. This work brings an overview of the thermo solar generation in Brazil, showing the different technologies and a thermodynamic simulation of one of such technologies considering a hybrid plant with complementary generation biomass, aiming at the generation of 1 MW in the Brazilian Northeast

Análise da viabilidade do uso de biogás gerado a partir de dejetos bovinos em microturbinas para fins de geração, cogeração e trigeração de energia

The use of digesters has become an important alternative for the proper disposal of organic agricultural wastes, serving as a solution to some environmental and health problems. Furthermore, the process of digestion provides commercially valuable by products such as biogas and bio fertilizer. The generation of biogas from agricultural waste, and its use in power generation systems has aroused great interest in rural areas because it enables supply in whole or in large part the energy demand of ownership by reducing production costs. The advent of technology has brought new forms of energy conversion of biogas, as the use of micro turbines specifies to be fuelled with biogas derived from the decomposition of organic matter in digesters, since it has a low level of methane in its composition, and high degree of impurities such as hydrogen sulphide, which are harmful to equipment and reduce the calorific value of biogas. The use of micro turbines behind other advantages like low emissions, great fuel flexibility and low maintenance. This paper presents an analysis of the feasibility of using biogas generated from cattle manure in micro turbines to generate electricity. Behind also an assessment of the energy potential that each animal has on various uses of biogas, and forms of energy recovery from the exhaust gases of the micro turbine. Also conducts an evaluation of the energy savings that the use of biogas aggregates properties.
