Main Spray Patterns

  • Solid cone — stable flame, general-purpose usage
  • Semi-solid — universal spray, more hollow at higher flow rates
  • Hollow cone — clean, quiet flame with optimal air mixing
  • Flat spray — for specific combustion chambers
  • Square pattern — even flame distribution in rectangular burners
