GLSF Min-Emissions Round Flame Gas Burner

GLSF Min-Emissions Round Flame Gas Burner

This photo shows Zeeco’s GLSF Min-Emissions round flame burners in operation.

The design allows for a compact flame shape which is basically the width of the burner tile making Zeeco’s burners a great choice for applications that require the burners to be mounted close together or far apart while still achieving Ultra-Low NOx.

Burner Description:

The Zeeco GLSF Minimum Emissions, gas only burner is an ultra-low emissions burner designed to provide a round flame shape for process type heater applications.

Burner Design Features:

  • Round flame, gas only burner design
  • NOx reduction method: Internal Flue Gas Recirculation (IFGR) by mixing the gas fired from the secondary gas port with the inert products of combustion which lowers thermal NOx production
  • Combustion air induction: natural, forced, induced & balanced draft, or turbine exhaust
  • Mounting options: up-fired, side-fired, and down-fired
  • Stable flame over a wide range of conditions
  • No stabilization metal used in the burner throat
  • Low maintenance cost since tip mass is small and exposed into firebox less than 1" (25 mm)
  • Compact design makes this burner a great choice for retrofit applications
  • Compact flame shape
  • Great heat flux profile
  • Reasonable cost and great value
  • Combustion air is controlled by gears for precise control
  • Bearings are used for the combustion air dampers for smooth, precise operation
  • Configurations available: plenum mounted or individual wind-box
