Looking for a 400-600 C electric burner / heating element? Answered

Im working on building a stirling engine which is powered by heat. The bottom cylinders will need to be heated to 4-600 C.  A burner similar to an older spiral stove burner would work but I'm afraid it wouldn't be able to reach the required temperature range.  The diameter of the burners surface needs to be at least 3 inches. Ive searched and searched but am unable to find much that looks like it will work.  Could someone explain how to possibly make something with some sort of heating element?  Any ideas?

You need to know how much POWER you will need, as well as the maximum temperature. You can readily buy heating elements you can wind around your cylinder.

Well for a power source i have purchased this:

Which might not even be able to power a heat source that ill need in the first place..

As far as maximum temperatures, the cups are 304 stainless steel which has a melting point of approx 1400 degrees C. Id say at a certain point that the engine will be at maximum power, but I don't know what that point is yet.

You'd get more power by simply pressurising the engine than the problems you'll get with losses running at 1000C.

Don't even THINK of solar-electricity to power it - just focus the sun on the hot end !

Thats one of my solar sources - via a fresnel lens. This is a gradate project for school so I would like to do a second type of solar energy for comparison.

Since this specific engine requires such high temps the only other way I could come up with would be solar panel to electric heat.

I think you're on a hiding to nothing using solar electric which is ~20% efficient if you're lucky.

Try a parabolic reflector instead.

There are some ibles about your sterling engine

The engine works on a temperature  difference,
what are you doing about the cooling end ?

One side is heated, the other is just air cooled. Thats why im looking for a surface heat rather than placing the engine in an oven so to speak.

Stove burners will get hot enough to melt led, zinc, tin, and aluminum. However they will not last very long and may burn out on every use.

So they should work good enough to test your engine.
