Montagem de um grupo gerador a partir de um motor a gasolina de 18 hp e um gerador elétrico de 2 kw, para funcionar com gás pobre

Abstract

Nowadays world-wide fossil fuel dependency brings out the need of searching for alternative sources of energy. In this work we tried to use a generator set as auxiliary source of energy. In fact, this generator set came from an assembly of an internal combustion engine, powered by gasoline, of 18 HP, and a generator of 2 kW already existing in the Laboratory. Seeking agility, the engine and the generator were mounted on different platforms. Since our purpose was to operate the engine with the lean gas produced by a gasifier. With the engine being powered by gas, it was necessary to install an air / gas mixture controller, developed in the Innovation Lab itself. When it was found that the double base support for the generator set caused immense vibration problems, we sought to correct the problem in a simple way, by adopting a single base, capable of facilitating the alignment of the equipment axes. This base was supported by cushions with the generator set put in a single platform and, we once having mastered the regulation of the air / gas mixer, it was possible to assure the power generation in a scale above the expected.
