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.

  • Furnace convection section robotic cleaning improves energy efficiency

    Excessive fouling in the convection section of fired heaters and furnaces results in higher fuel consumption to achieve the required output. This causes high stack temperatures, reduced heat transfer, and increased emissions, which can lead to government fines and environmental damage. Fouling occurs ...

  • Optimizing heat flux distribution to prevent heater tube coking with dual emissivity Cetek coatings

    Cetek’s patented Dual Emissivity Ceramic Coating technology manipulates and optimizes the heat flux distribution in DCU heaters which would otherwise be susceptible to coking inside tubes.

    We designed the dual emissivity coating system to maximize benefits based on the coking pattern of ...

  • How to fix a tube in a fired heater furnace without SD - Hot Tube Stabilization

    Occasionally, tube supports (wall and roof) in the radiant section of process heaters fail, allowing the process tubes to potentially get out of alignment (sagging or bowing) or even worse, rupturing.

    IGS Hot-tek provides on-line repair service to stabilize the process tubes while the heater ...
