Comparison of CO and NO Emissions from Propane, n-Butane, and Dimethyl Ether Premixed Flames

We report a comparison of CO and NO emissions from dimethyl ether (DME), propane, and n-butane laminar premixed flames. Measurements were made with a water-cooled stainless steel sampling probe situated above the visible reaction zone of a co-flow burner. Species were measured by a Nicolet Magna 550...

Zusammenfassung:We report a comparison of CO and NO emissions from dimethyl ether (DME), propane, and n-butane laminar premixed flames. Measurements were made with a water-cooled stainless steel sampling probe situated above the visible reaction zone of a co-flow burner. Species were measured by a Nicolet Magna 550 FTIR spectrometer. The fuels were compared on the basis of constant mass flow, constant C-atom flow, and constant firing rate. Results were corrected for dilution by entrained air. Our results indicate that on all bases considered, DME demonstrated lower CO emission than propane and n-butane over a broad range of stoichiometries. NO production from DME was generally less than or similar to propane and n-butane over the same stoichiometric range. We conclude that in terms of its relative CO and NO production, DME is a viable alternative utility fuel.
