GLSF Free-Jet Flat Flame Gas Burner

GLSF Free-Jet Flat Flame Gas Burner

The picture in the gallery is Zeeco’s GLSF Free-Jet flat flame burner in operation at our test facility in Broken Arrow, Oklahoma. The Free-Jet burner design is able to achieve great NOx emissions and heat flux profile. Wall-fired and free-standing versions are available to be tailored for the customer's specific application. For wall-fired applications greater than 6 MM Btu/hr [1.758 MW] the burner will have gas lances tailored for the heat flux profile and to keep the flame from rolling over toward the tubes.

Burner Description:

The Zeeco GLSF Free-Jet burner is a Next Generation emissions flat flame burner.

Burner Design Features:

  • Stable flame over a wide range of conditions
  • High turndown of 10:1 or greater for most cases
  • No stabilization metal used in the burner throat
  • Tips have only a single firing port and do not require a small ignition port
  • Low maintenance cost since tip mass is small and exposed into firebox less than 1" (25 mm)
