Five Common Causes of Refractory Failure and How to Fix Them
By Integrated Global Services Inc IGS
All process heaters operate at high temperatures and are constructed with process tubes inside a refractory-lined enclosure, which is heated by radiant heat from gas-firing or, less commonly, oil-firing.
Refractory linings are insulating and minimise heat loss, making them essential to retaining the
high-temperature environment. However, when subjected to high temperatures, refractory
can deteriorate and potentially lead to failure if remedial work is not carried out.
