Hi there, Im trying to design a heating module to quickly heat a small particle (~1-2mm) to around 1500C in air. Im going to use a MoSi2 coil or similar to do this. The coil i am considering has a diameter of 25mm with wire diameter 3mm, 5 turns and hot zone length 50mm. This equates to a total of around 20cm of hot wire.
I am a mechanical engineer and so am a bit lost with the electronics side of things. Could anyone give me a hand?
The way i figure it is, thermodynamics tells us that
Q=Aσε(T^4) and Q=hΔT
and Q=I²R
So does this mean we can deduce the required current if we know the properties of the element (surface area A, convective heat transfer coefficient h, emissivity ε, temp T and resistance R)
I would like to use Uk mains voltage and I understand that I will need a thyristor and transformer of some sort. Does anyone know of any beginner guides to designing a system like this?
I was planning on using a feedback system with a series, cooled resistor in order to approximate the resistance and hence temperature of the element.
If anyone has any advice or comments, they would be much appreciated!
