GLSF Free-Jet Down-Fired Gas Burner

GLSF FREE JET Down-Fired Gas Burner

The picture in our gallery is Zeeco’s GLSF FREE JET down-fired burner firing at our Combustion Test Facility located in Broken Arrow, Oklahoma. This design offers up to 90% NOx reduction as compared to conventional burner designs. Dual fuel connection versions and single connection versions of this burner can be offered. The FREE JET mixing method allows a single connection in applications when PSA fuel is mixed with fuel gas.

Burner Description:

The Zeeco GLSF FREE JET burner is a Next Generation emissions round flame burner.

Burner Design Features:

  • Stable flame over a wide range of conditions
  • High turndown of 10:1 or greater for most cases
  • 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)
  • Low maintenance cost since the tips do not have small ignition ports which are prone to plug
  • Compact design makes this burner a great choice for retrofit applications
  • Low probability of flame interaction since the burners are smaller and gas is not swirled
  • Reasonable cost and great value
  • Great heat flux profile
  • Combustion air dampers are controlled by gears for precise control
  • Bearings are used for the combustion air damper shafts for smooth, precise operation
  • Configurations available: plenum mounted or individual wind-box
  • Burners can be designed for either two fuel connections or one fuel connection
  • 304 Stainless Steel fuel gas risers
  • 310 Stainless Steel (Type HK) gas tips
