  "id": "MLC-T-CHM-010753",
  "term": "Separated flame",
  "field": "Chemistry",
  "definition": "A premixed flame whose observed region is shielded from room air mechanically, by a tube fitted around the flame on top of the burner, which creates a zone boundary between the flame gases and the air. When the shielding is done instead by a curtain of inert gas flowing out of holes in the rim of the burner, the result is called a shielded flame.",
