Concepção e construção de um fogão solar do tipo parabólico para cozimento dos alimentos

Abstract

The problem of destruction of mangrove forests to obtain wood fuel has had a negative impact on the estuarine environment. A parabolic stove based on local material has been designed and built to reduce pressure on the mangrove cut. The stove was built with a Tv dish with length 88cm and a width of 82cm and the concave part overlaid with aluminum foil usually used for food preservation. The stove in study when compared with others already constructed by other authors in which two parabolas were used for the reflection of the solar radiation demonstrated to be competitive because with the obtained temperature it is possible to cook certain foods. This stove was built to reduce the environmental damage caused by the massive use of firewood for the cooking of food mainly for communities living in areas of mangroves that in recent times has increased population and also intensified the killing of mangrove trees. Although this energy technology is environmentally friendly to nature, it has its drawbacks that it can not be used on cloudy days and at night, as well as taking care of reflected rays at the time of use.
