Restoring production efficiency & NOx reduction by eliminating SCR fouling
Problem: SCR fouling is typically caused by refractory or insulation fibers that accumulate and block the face of the catalyst, eventually leading to substantial flow disruption and excessive pressure drops, typically worsening over time. This pressure drop and flow maldistribution will cause production rate limitations, unplanned outages, and environmental compliance issues, as well as reduce he catalyst life.
Solution: Proven methods for keeping SCRs operating efficiently include:
- Immediate Relief to Keep System Online: Hot-Tek Online Vacuuming Services
- Long Term Solution: Fine Particle Filtration Screen System
- Removal of the Captured Material: Screen Online Cleaning System
- Reducing the Volume of Fibrous Material: Refractory Encapsulation

Eliminate convection section fouling by encapsulating refractory
Problem: Over time refractory ceramic fiber becomes friable. This friable dust is entrained in the post combustion flue gases and gets carried downstream, fouling convection section tubes and catalyst banks. Fig 1 shows new ceramic fiber under SEM. Fibers are continuous and intact. After heat exposure, ...

Eliminate fouling of radiant tubes
Problem: An increase in Bridgewall temperature can be a symptom of excessive fouling of the fired heater’s radiant tubes. These tubes tend to oxidize under operating conditions. Solution: Our patented Hot Tube Descaling service removes radiant section process tube fireside soot, scale, and fouling ...
