For addressing catastrophic failures, meeting regulatory requirements, or improving efficiency, FEECO can supply a burner to meet the requirements of your unique rotary dryer or kiln.
Common Reasons to Replace or Upgrade a Burner
Catastrophic Failure or End-of-Life
When firebox damage, flame tube failure, or combustion air issues occur, a full burner replacement is required.
To Maintain Regulatory Compliance
Producers may need to upgrade or replace their burner to maintain regulatory compliance in the face of tightening emissions limits or when feedstock composition changes.
Switching Fuel Sources
Moving from one fuel source to another (e.g., #2 oil to natural gas) due to cost or availability requires a compatible burner.
Changes in Capacity
The need to increase or decrease throughput often translates to a change in burner specifications.
Efficiency Improvements
Producers relying on older burners with poor turndown ratios or incomplete combustion often experience higher fuel costs that can be mitigated with a more efficient, modern design.
Hard-to-Source Legacy Burners
Outdated or obsolete burner models may be difficult to find parts for or challenging to repair.
FEECO can reverse-engineer replacements for discontinued or obsolete burner models.
Burner Capabilities
FEECO can design burners for a multitude of applications configurations:
- Multi-fuel capability: Accommodate natural gas, propane, diesel, fuel oil, or dual-fuel combinations.
- Flame shaping: Burners engineered to achieve specific target temperature profiles along the drum’s length in high-temperature settings.
- Custom sizing: Burners designed according to drum diameter, length, and process requirements.
- Combustion air systems: Integrated or standalone combustion air delivery options.
- Controls integration: Compatibility with existing burner management systems and fuel train controls.
Replacement Components
FEECO can also supply burner replacement parts, including:
- Gas regulators
- Valves
- Meters
- Relay outputs
- Pressure switches
- Shut-off valves
- Ignitors
- UV scanners
- Thermocouples
Frequently Asked Questions (FAQs)
A properly maintained burner can last for decades. However, as technology advances, it may be desirable to replace the burner in favor of one that is more energy efficient, that adheres to changing emissions regulations, or is being adapted to process another material.
Lead time for a burner can range from 4 to 8 weeks.
Burner replacement is a good time to consider replacing the combustion chamber if necessary. If the system does not use a combustion chamber, it may be a good time to evaluate whether or not the addition of a combustion chamber could benefit the process. During this review process, it may also be a good time to evaluate whether the system meets NFPA regulations and the burner control system meets process control strategy needs.
