Abstract

The following report describes the work performed over a two month period at a company called Ecofogão. Ecofogão produces wood burning stoves that utilizes a new design to increase efficiency and reduce emissions. Many individual projects were worked on during the internship. This report has been divided into sections for organizational purposes. Projects discussed included fan implementation and gasification, griddle design, efficiency testing, cost analyses, design analysis, a social project, website translation, and a photography project.

Some conclusions regarding the projects were obtained. The implication of a fan in the stove for gasification proved to be unsuccessful. A new griddle design was proposed, which includes employing an orifice with a detachable plate to maximize the efficiency. Efficiencies for different models of the Ecofogão were found to be 12%, 21% and 28%. The cost analyses yielded slight increases in the production costs for three stove models, and a decrease for a fourth model. Also discussed are vast improvements in the marketability of the stove through slight alterations of the design. The social project has helped participating families economize an average of 294% of money they formerly spent on fuel.
