Abstract

Diethyl ether (DEE) is being considered as a promising biofuel. The combustion chemistry of DEE in a fuel-rich low-pressure laminar premixed flame was studied. The laminar flame speeds of DEE iwas measured n a constant-volume chamber at elevated pressure. A new detailed kinetic model was proposed to describe the combustion of DEE in particular with respect to intermediates and pollutant formation. DEE flames yielded low concentrations of aromatic species. However high acetaldehyde emission was observed originating from the dominant pathways of DEE consumption via H-abstractions from C positions followed by β-scissions.
