Projeto básico de queimador tipo flare autoaspirante operando com biogás

Abstract

Atmospheric burners are devices that carry out combustion under low gage or atmospheric pressure, and may be self-priming or with air supply. The requirements and regulations that demand the reduction of greenhouse gas emissions are becoming increasingly strict and atmospheric burners can help to mitigate this effect and provide safety in many cases. The present study carried out through the Laboratory of Combustion and Renewable Energies was carried out the design and simulation of this type of burner in order to analyze the equivalence ratio (Φ) of the primary fuel air mixture, pressure and velocity along the burner. The burner is designed for a pressure of 17 mbar and a flow rate of 0.5 m³/h. The analysis was performed through calculations from empirical parameters and computer simulation using COMSOL software.
