Implementation and testing of the use of vegetable oils as fuel diesel generators in the Amazon isolated communities; Implantacao e testes de utilizacao de oleo vegetal como combustivel para diesel geradores em comunidades isoladas da Amazonia.

The project PROVEGAM calderass and test of a unit demonstration of energetic utilization of vegetable oil’, tested in operational conditions of field, the functioning of a conventional diesel engine, adapted to operate with palm oil ‘in natura’ in the community of Vila Soledade, city of Moju, Para State.

The Vila Soledade is an isolated community caldefas has, approximately, inhabitants and it’s located at one hundred kilometers from the city hall by car and more 30 minutes by boat. The electric energy of this community was previously generated, by a conventional diesel engine, obsolete and very expensive to the community, because the fuel price and the transport of the diesel oil from the city to the community.

Because of the viscosity of the palm oil and its combustion point, it was necessary to heat the vegetable oil before its injection into the engine. The operation begins and finishes with diesel oil, in order to heat the palm oil and to clean possible residues deposited in the interior of the engine. The use of the palm oil justifies itself for being produced in the region, which means that it doesn’t have to be imported.

Currently, the generating group is working in pirrotubulares community during 5 hours per day with palm oil, and 1 hour per day with diesel oil and it already has more than hours of testing. The results of this project, so far, have confirmed the conceived premises, and this electric model of generating energy is already recommended to be implemented in other communities in the Amazon region.

Directory of Open Access Journals Sweden. The study of mineral diesel alternatives, such as biodiesel, a renewable fuel, is important for the environment and to diversify energy sources. Specific fuel consumption, calorific value and the overall efficiency as a function calderqs the system load was measured, using diesel oil and biodiesel blends. The engine that was used during the test has a power of 7. The group was submitted to resistive loading, in the range: The results have shown.

In the current scenario of constant power drops in Brazil and an imminent crisis in the electricity sector, the use pirotubullares generators and biofuels such as biodiesel has been quite common in rural areas represents an option for diversification of the energy matrix. This study evaluated the use of soybean biodiesel in different concentrations in a diesel engine cycle under different demands of engine loads.

Tests were conducted to quantify. Comparative analysis between two systems to generate electric energy for isolated community in the interior of the Amazon state: Although great part of the domestic territory is already supplied with electric energy, still there are many regions where the system is precarious or nonexistent, generically called isolated communities.

In the majority of the cases these communities are supplied with Diesel oil generators and the substitution of this fuel for available alternative energy in the localities has been object of study of some institutions of research spread throughout the country.

Currently, the use of fuel cells has been strongly argued in the generation of electric pirotubulards associated with the local energy necessity, from the use of a regional fuel and this is due to the high efficiency of allied energy conversion to the low ambient impacts that this equipment offers. Most of the different types of fuel cells use hydrogen as a fuel to produce electricity, calferas it is extracted from renewable or non-renewable sources of energy. Then, the article has the objective of comparing in first analysis the energy efficiency and the cost between the two systems: This article reports on a case study which applied the model called Map for the Identification of Potential Intangible Asset Generators.

In Brazil the trend that biodiesel be used with regular diesel is increasing. As a result feasibility studies are becoming more necessary. The objective of this study was to evaluate use of biodiesel in different concentrations with diesel B3, B5, B10, B20, B50 and B in a generating group diesel.

Assays for quantification of the hourly consumption of fuel and emission of noise in different variants of the engine had been carried out. This was pirotuhulares through the electrical charge, connected to the generating group, and carried out through the analysis of the degree of Bosch blackening of the gases of exhaustion in the different concentrations. The equations of regression had good correlation with the real data.

Justificando la confianza desde 1949

In conclusion the electric charge applied to the group generator increases proportionately with the time consumption and the emission of noise. However Biodiesel B is different in comparison to other mixtures in the Bosch blackening test, presenting a lesser emission in relation to the other mixtures.
