Silicon Carbide Radiant Tube Inserts
Silicon carbide is the preferred material for radiant tube inserts due to its high thermal conductivity, thermal shock resistance and high-temperature capability. These properties improve heat transfer and furnace efficiency while reducing energy demand. As a result, manufacturers can achieve long-term energy savings and lower greenhouse gas emissions in heat treatment, galvanizing and annealing processes.
SpyroCor® has a patented twisted-fin design that boosts turbulence inside the radiant tube. This helps transfer more heat from combustion gases to the furnace chamber. By increasing turbulence of combustion and exhaust gases inside the radiant tube, SpyroCor® improves heat transfer and helps manufacturers improve efficiency while reducing energy demand.
By improving thermal efficiency, SpyroCor® helps manufacturers:
- Reduce fuel consumption by up to 15%
- Increase productivity by up to 10%
- Lower CO₂ emissions
- Reduce operating costs
- Improve furnace performance
Its retrofit-friendly design allows installation in existing furnaces without major modifications, delivering measurable energy savings with limited downtime.
NOxBuster® has been specifically developed to reduce nitrogen oxide (NOx) emissions generated during combustion processes. The reduction of NOx emissions and other greenhouse gas emissions helps manufacturers lower their carbon footprint and support decarbonization strategies.
Its innovative design can lower NOx emissions by up to 50% while maintaining efficient furnace operation and productivity.
For manufacturers facing increasingly stringent environmental requirements, NOxBuster® offers a practical solution to support decarbonization initiatives and improve environmental performance.
Radiant tube inserts can be installed in various radiant tube configurations, enabling straightforward integration into many industrial furnace designs.
Available configurations include:
- U-Type radiant tubes
- W-Type radiant tubes
- Straight radiant tubes
- Tri-Type radiant tubes
This flexibility makes SpyroCor® and NOxBuster® suitable for a broad range of furnace upgrade projects.

FAQ
What sort of materials are used to create radiant tube inserts?
Silicon carbide tends to be used in radiant tube inserts, because of its extensive thermal stability and ability to withstand oxidation, however there are other materials that can be used as well. These include aluminum, steel, ceramics, and alloys.
Are there any temperature limits for radiant tube inserts?
The temperature limits of radiant tube inserts depend on the materials they are made out of. For instance, a radiant tube insert made out of silicon carbide could be used in temperatures that meet 1,250°c. But a radiant tube insert formed from cast steel is different and can only resist temperatures reaching 1,100°c. SpyroCor® radiant tube inserts can be utilized till temperatures hit 1,380°c.
Are there any environmental benefits to using radiant tube inserts from Saint-Gobain Refractories?
The SpyroCor® radiant tube insert has a patented twist fin design. Its design helps it to take in heat and move it back to the furnace. By utilizing this design, the amount of carbon generated and energy used can be lowered by around 5-15%. Moreover, the NOxBuster® radiant tube insert can be used to lower NOx emissions by 50% at most.
Why Improve furnace thermal efficiency?
Rising energy costs and increasing pressure to reduce carbon emissions are driving industrial manufacturers to optimize furnace operations.
Even small efficiency improvements can generate substantial annual savings across heat treatment, galvanizing and annealing operations.
SpyroCor® provides a practical solution to improve furnace performance without major capital investment.
