Characterization of Biogas-Syngas Turbulent MILD ‎Combustion in the Jet in Hot Co-Flow Burner

Moderate or Intense Low–oxygen Diluted (MILD) combustion is a promising technology with interesting ‎properties such as high efficiency and zero-emission. The biogas-syngas mixture is also considered a ‎promising new renewable biofuel with low emissions. This work aims to examine the effects of seve...
