Note: Heating fluid passing through an alumina tube

Objective:

To heat an alumina tube to heat magnetic particles in a fluid passing through the tube 

End Product:

Fluid heating

Equipment:

Ambrell EASYHEAT 2 kW, 150-400 kHz induction heating power supply with a remote workhead containing one 0.17‚ μF capacitor
A single-position, fourteen turn helical induction heating coildesigned and developed for this application 

Materials:

Nanoparticles
Alumina tube (0.5 in 12.7 mm diameter)
Thermocouple to measure temperature

Temperature:

150 °F (66 °C)

Frequency:

295 kHz

Testing:

The alumina tube was placed in the coil and water was sent through it at a rate of 80 ml per 40 seconds. The energy delivered from the EASYHEAT was sufficient to heat the fluid to temperature at a rate of 120 ml per minute. 

Benefits:

  • Speed: Induction was able to achieve the client’s targeted speed/production rate

  • Repeatability: Induction will be able to achieve an identical result consistently

  • Energy savings: The speed at which induction heats the fluid to temperature meets/beats the client’s speed objectives which will result in energy savings
