GLSF Free-Jet Flat Flame Gas Burner Video
The picture (right) 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)
- 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
- Great heat flux profile
- Reasonable cost and great value
- Combustion air dampers are controlled by gears for precise control
- Bearings are used for the combustion air damper shafts for smooth, precise operation
