Note: Heating a Tube to Heat Gases
Objective:
To heat an Inconel tube for a gas heating application
End Product:
Equipment:
Ambrell EKOHEAT 20 kW, 15-40 kHz induction heating power supply with a workhead and coil specifically designed for this application.
Materials:
Inconel, 1.375 in (34.9 mm) outer diameter, 1.0 in (25.4 mm) inner diameter
Temperature:
1,472 °F (800 °C)
Frequency:
27 kHz
Testing:
A custom-designed multiple-turn helical coil was developed for this tube heating application. Initial tests were conducted to optimize the power delivered to the tube. laboratory evaluation confirmed the feasibility of the process for heating the customer-supplied tube to the target temperature with an Ambrell EKOHEAT solid state induction power supply.
Benefits:
-
Repeatability: Induction delivers the same result every single time, making it a repeatable solution which is critical to processes like this one.
-
Speed: Induction has no warm-up time like an oven and can quickly come up to temperature. Induction met the client's timing objectives.
-
Footprint: Induction takes up a modest amount of floor space, especially when you consider that the workhead can be placed a distance away from the power supply.
-
Safety: Not only is induction heating efficient, it also offers safety advantages as there is no open flame.
