Help with Induction heating for steam

Hi,

I'm working on a project that would require the ability to heat water into steam via electric induction, preferably DC or via AC converter if necessary.

I'm thinking a monotube design with an induction coil surrounding it that could produce steam from 2 quarts of water in say 30 seconds or less.

Anyone here have experience with that kind of design?

Thanks,

Why go with induction heating? You can only heat the container holding the water, so the water still has to absorb the heat by conductive/convective heat transfer. And the induction power supply will have significant efficiency/energy losses. If you're thinking of microwave heating of the water, you're still talking big efficiency losses; just compare the power input on a microwave to the rated output.

Why not just go with bayonet resistance heating elements inside of close fitting tubes of water, you'll get 100% heating efficiency. Or resistive heating of the tube shells.

Definitely use a single tube. I would use one with vanes on the inside to maximize surface area between the water and the metal.

Get a copy of Davies & Simpson's Induction Heating Handbook through interlibrary-loan.
