Resumo: Using Natural Gas or Biogas in natura, containing high hydrogen (H2S) sulfide concentrations, to apply in conventional combustion processes, can cause several damages to equipment. This is due to the fact that it is a very corrosive gas that can form a sulfur acid reaction with water from combustion. In addition, using these fuels without pretreatment can cause instability on reaction, even under flame risk deletion, which implies in efficiency and oxide carbon (CO) and nitrogen oxide (NOx) emission levels. Therefore, this study refers to the experimental method of non-conventional combustion process application, the porous media combustion, also known as filtration combustion, to deal with these special fuels, impossible to use in known thermal systems. A burner all filled with alumina spheres (Al2O3) was the equipment used for these experiments. This inert porous media fills even the heat exchangers located on the ends of the burner. The equivalent ratio, flow velocity and gas composition influence in the process, are experimental analyzed. Preliminary results have suggested that when using an ultra-lean air-fuel mixture, the reaction can remain steady with a good H2S conversion and low CO and NOx emissions.
