Objective: |
Determine the emissions formed in DME diffusion and premixed flames and compare to propane and n-butane |
Approach: |
Measurements were made of NO and CO emissions from DME, propane and n-butane flames using a water-cooled sampling probe and two burners: an annular co-flow diffusion flame burner and a premixed flame (McKenna style) burner. |
Results: |
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. DME burns with a non-luminous flame and the DME flames were typically much more compact. |
