Customized Silicon Carbide Ceramic Pipe Burners Finned Radiant Tubes

Feature

1. Wear resistance.

2. Oxidation resistance.

3. Corrosion Resistance.

4. High temperature tolerance.

Heat flow: 110 BTU/in²

Si/SiC radiant tubes can be used in all heat treatment processes in gas or electrically heated hardening or tempering furnaces and adapt to your existing burners. The tubes can be supplied with open ends, closed ends (recuperative system) and with corresponding flanges. Exchange systems ready for installation with radiant and flame tubes up to 6” diameter made of Si / SiC composite material for recuperative burner equipment are available immediately.

Si/SiC recuperative radiant tubes are absolutely maintenance-free.

Finned Tubes + Uniform Temperature = Considerable Energy Savings

Open tube systems have been used for many decades, primarily for tempering furnaces. The recuperative burner systems, however, are relatively new.

AVION finned radiant tubes offer a larger surface area considerably improving their heat efficiency and distribution.

Because the fins are thread-shaped, an optimum flame distribution from the burner tip to the tube exit is achieved.

Further advantages of Si / SiC radiant tubes are:

• Durability and reliability at temperatures up to 2450°F
• Outstanding resistance against:
• Thermal shock
• Overheating
• Oxidation
• Carburization
• Creep elongation
• Corrosive atmospheres
• Vibration
• Magnetization
• Residues of detergents

Heat flow: 125 BTU/in²

SILICON-CARBIDE INSERTS for Radiant Tubes

ZG Industrial. is a supplier of radiant tube inserts made of Silicon-Carbide. The patented twisted “Y” design produces non-turbulent high convection flow. The subsequent radiated heat from the SpyroCor™ results in the highest rate of uniform heat transfer possible.

In a traditional radiant tube, 45% more energy is released in the burner leg than the exhaust leg due to the highly luminous flame. Both radiation and convection heat transfer are present in the burner leg. The hot gases in the exhaust leg have an emissivity of less than .05. Thus, convection heat transfer is dominant in the exhaust leg.

To Save Fuel ,with an emissivity of .95, are installed in the last 2/3’s of the exhaust leg. Radiation and convection heat transfer are now present. The exhaust leg and burner leg are now balanced from a heat transfer standpoint. Input into the radiant tube burner is reduced by 20%. Energy available to the load is maintained.
