High temperature thermal processing is an extremely challenging industrial niche with various conflicting performance indicators demanding time and resources. At the most fundamental level, it can be difficult simply generating the temperatures necessarily to carry out key processes. Higher up – at the decision-making level – pressures range from pushing greater productivity to drastically reducing maintenance costs; all in the name of improving profitability.
Radiant refractory tubes are a novel burner solution engineered to satisfy strict demands across the full spectrum of the production chain.
Comprising a straight tube-in-tube design made using high-purity silicon-infiltrated silicon carbide (SiSiC), Saint-Gobain radiant refractory tubes can output as much as twice the energy of standard alloy radiant elements into furnace environments. To put that into context, high-temp steel alloys used in industrial heating typically reach a maximum net heat output of 25 kWatts per meter squared (kW/m2) compared to the 50 kW/m2 of our reaction bonded Silit® tubes.
They protrude into the chamber – horizontally or vertically – and radiate heat outwards as fuel gas is burned within the hollow core, providing high thermomechanical stability up to temperatures of 1380°C.
At Saint-Gobain Performance Ceramics & Refractories, we strive to deliver excellent product solutions through material expertise. Our refractory radiant tubes comprise just a segment of our total burner solutions and can be coupled with various inserts and recuperators to improve the performance parameters that matter most to you. Additional burner solutions that are compatible with our radiant refractory tubes include:
