Down-Fired GLSF Free-Jet Burner Video
The picture (right) 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
