The picture (right) is of Zeeco’s GLSF flat flame burners in operation in an ethylene cracking furnace. The design allows for flat flame burners to achieve a great heat flux profile without flame rollover. A major advantage is that the heat flux profile can be changed as required for the specific application with different tip drilling configurations without adversely affecting NOx emissions. The design is currently in service in over 100 ethylene cracking furnaces. Since the heat flux profile can be adjusted for different requirements, this design is also a perfect match for coker, cabin heater, steam super-heater, hydro-cracker, and reformer type applications.
Burner Description:
The Zeeco GLSF Min-Emissions Enhanced Jet burner is an Ultra-Low emissions flat flame burner.
Burner Design Features:
- No flame rollover makes this design a great choice for ethylene cracking applications
- Great heat flux profile that can be modified for the particular type of application
- Stable flame over a wide range of conditions
- High turndown of 8:1 or greater for most cases
- 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
- 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
- Configurations available: plenum mounted or individual wind-box
- Mounting configurations: Horizontally mounted, vertically fired and vertically fired
- 310 Stainless Steel (Type HK) gas tips
