We designed the dual emissivity coating system to maximize benefits based on the coking pattern of the Delayed Coker firebox.
The process consists of the application of coatings to the refractory. We also remove all tube scale, and install a uniform ceramic coating system to the tube surfaces.
This dual emissivity coating system effectively shields the tube surfaces in high heat flux areas but increases heat absorption in lower heat flux areas. This prevents rapid coke formation while at the same time eliminating uneven scale formation, thus allowing accurate tube metal temperature measurements.
The coatings are applied by Cetek’s highly trained, experienced technicians, following thorough cleaning of the tube surfaces. Coating systems are available for every type of metal and refractory substrate as well as process temperature.
The coatings are inert, non-catalytic, and water-based, offering a complete environmentally safe process improvement. The service is supported by a superior Health & Safety Program, yielding a safety record better than industry standards.
