Elevated Flares

Steam Assisted Flares (EnviroMist Series)


  • Provides smokeless combustion of heavy waste gas vapors
  • Steam is injected into the combustion zone to induce atmospheric air
  • Upper ring and / or lower induction tubes used to deliver steam
  • High velocity steam injection creates a turbulent mixing zone for greater combustion efficiency

Selection Criteria / Advantages

  • Smokeless flow rates of up to 100% of total waste gas flow
  • Steam is a readily available utility
  • Center steam sparger used to minimize flame burn-back thus increasing tip longevity
  • Stable and reliable combustion
  • Petroleum refining
  • Chemical processing industry (CPI)
  • Flame retention devices(s) ensure stable combustion
  • Designed to accept a wide range of waste gas pressures
  • High temperature rated materials in the heat affected area
  • Includes velocity type purge seal to prevent flashback and minimize operating expense
