NOx emission from combustion systems is still a topic of interest to many researchers. New combustion systems were designed with the latest technology to reduce the emission of NOx and other pollutants. The reburning of NOx using porous burners was studied. These burners were quite effective in stabilizing flames at wide range of operating conditions and were classified as low pollutants emission burners. An experimental porous burner was developed. The burner consists of two different pore-size of silicon carbide foams insulated using KAOWOOL paper (2600 grade) following by KAOFIL PUMPABLE. Premixed air and fuel is fed through a mixing chamber, wherein NO and other diluents such as nitrogen and CO2 can be added to the mixture. Up to 90% reburning of NO was achievable when operating at very rich conditions. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
