Help with Induction heating for steam

carlos_growFebruary 2, 2008


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?

If my calculations are correct:

2 quarts of water = 4 lbs.
Temperature rise from 62F tap water to 212F = 150F rise.

1 BTU = 1 lb water 1F
so you would need 600 BTU's (but that's for 1 hour)

if you want it in 30 seconds (120th of an hour), you would need 600 BTU x 120 = 72000 BTU

1 Killowatt = 3400 BTU

72000 / 3400 = about 21 Kw

at 240 volts that = 87.5 amps

If you start with 140F water (72F rise), you could get by with half the energy needed:

240v 44 A

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.
