Hot spot repair - online fired heater refractory repair

Hot Spot Repair in Live Heaters. Hot spots in the shell of the fired heater limit capacity and can cause a forced shutdown. Our experienced global team mobilizes at short notice to repair refractory online.

What is Refractory Failure?
The refractory may fail prematurely due to the failure of support/anchors holding the lining in place or an operational upset. In these cases, the operator must decide whether to interrupt production by bringing the heater off-line to make a conventional repair or continue at reduced capacity until the next scheduled shutdown.

Hot Spot Repair Procedure Online
IGS has developed a proprietary Hot-tek solution for online hot spot repair. The IGS team creates minimal openings to insert specially designed components and repair material, delivering a semi-permanent repair lasting at least until the next planned turnaround.

Online Furnace Refractory Repair Using Existing Access Points
Furnace refractory repairs may also be made using existing access points and a Hot Gunning, or Hot Fiber Spray technique, in combination with Hot-tek’s hot inspection service. If access points are not available, our Hot Access Creation may be used as an integral part of the refractory repair process. In some applications, Hot-tek’s hot inspection service is used to see hard-to-reach areas of the fired heater.
