W-TUBE
Radiant W-tube combustion systems are an industry standard for the indirect heating of metals in a protective atmosphere. The W-tube, modular burner and plug-in type recuperator typically operate at temperatures up to 1,000°C and efficiencies of 70%.
Leveraging the power and reliability of Saint-Gobain Performance Ceramics & Refractories’ twisted channel HeatCor™ recuperator, twisted tape PyroCor™ flame tube, SpyroCor® radiant tube insert and NOxBuster® internal exhaust gas recirculatory can enable increased throughput, energy savings, reduced emissions and lower maintenance frequencies.

FAQ
The HeatCor™ is a new heat exchanger design that incorporates a higher surface area twist channel versus traditional fins and bumps. This increased surface area allows for an increase in effectiveness of over 10%.
PyroCor™ utilizes a specialized design and variable twists to optimize temperature uniformity in the radiant tube.
These infiltrated SiSiC high performance, non-porous ceramic materials can accommodate application temperatures of 1,380°C. They also offer excellent thermal strength properties.
The thinnest possible wall thickness is approximately 4 mm with Silit® and 2 mm with Amasic-3D™.
