CLSF MIN-EMISSIONS
Enhanced Jet Combination Flat Flame Burner
The picture (right) is of Zeeco’s Min-Emissions CLSF flat flame burners in operation in an ethylene cracking furnace burning C5 liquid.
This design allows for flat flame burners to achieve a great heat flux profile without flame rollover. Since the heat
flux profile can be adjusted for different requirements, the design is also a perfect match for coker, cabin heater,
steam super-heater, hydro-cracker, and reformer type applications.
Burner Description:
The Zeeco CLSF Min-Emissions Enhanced Jet burner is an Ultra-Low emissions flat flame combination 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
