The purpose of this work was to analyze the physical and chemical characteristics of charcoal briquettes, produced in three countries, and to evaluate their performance during the combustion process. To evaluate the behavior of these briquettes, it was developed a “combustion index”, which correlates the time combustion, temperature generate during the combustion, and used up mass. The physical and chemical characteristics studied were: moisture content, fixed carbon, volatile matter, ashes content, calorific value, apparent, actual and bulk densities, friability, and compression strength.
