- Abstract
The work has as its theme the analysis of the flammability limit of a solution of ethanol in water and the safety of the combustion of this mixture. The work was developed using the ethanol produced at UFSM, where the final product concentration is approximately 90% pure. Through the ethanol was carried out the procedure of analysis of the characteristics of temperature, time of burning, color of the flame. These characteristics were determined from different concentrations, starting at 90% and moving towards a lower value, every 5% until the flash point was reached for the ambient pressure, humidity and temperature conditions. The analyzes seek the flammability limits of hydrated ethanol and guarantee the safety of the use of biofuel. The final volume of the mixture for all tests was constant. The research is characterized as experimental, applied, descriptive and quantitative. With the analyzes it was concluded that the sample combustion time decreases as the water concentration is increased and that the samples are ignited at room temperature to 35% ethanol in water. And also, the maximum radiation dosage is 5 kW / m² for 60 s for people and equipment.
