Cetek high emissivity coating for fired heater refractory
Is your fired heater limited by bridge wall temperature, or firing duty? Instead of a full scale revamp, we may address these issues may by the application of Cetek’s High Emissivity Ceramic Coatings to the refractory surfaces. Cetek High Emissivity Ceramic Coatings provide improved efficiency of radiant heat transfer from refractory surfaces in gas-fired heaters. Coating application results in: Typical Productivity Benefits Raging From 2.5% to 5% Fuel Savings Capacity Increase Reduced CO2 and NOx Emissions Fiber Encapsulation Decreased Bridgewall Temperatures Rapid payback on investment.

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 ...

IGS Cetek catalytic reformer heater process tube coating
Thermal Inefficiencies. In a high temperature environment, steel alloy process tubes will oxidize immediately and scale will develop. This oxidation scale layer acts as an insulator and will lead to a decrease in heat transfer as the scale increases in thickness. To compensate for the insulating effect ...
