What would be the best, cheapest way to generate steam intended for introduction to a device for testing? I would use a standard American 110v three-prong outlet as a power source for the steam generator. All I really need is a steam source with an absolute pressure of 2 atm/202650 Pa/29.39 psi. The intended mass flow out of the generator would be 20-28g. I've looked at commercial/industrial boilers, but they generally operate at much higher power than the limits imposed by using a standard 3-prong outlet. They're also hauled on the back of trucks and produce much greater quantities of steam than indicated by my needs. I've examined the possibility of using dental sterilization equipment, but such would need modification to serve as a steam source, since they don't generally have any kind of outlet or blow-off valve (that I can tell). There's also the question of whether or not any of them can serve as a steam source for any non-trivial amount of time. All I'd really need is a reservoir with a blow-off valve to maintain maximum internal pressure of 2 atm, a pressure gauge, and an outlet. I could tailor a throttle plate to control flow through the outlet. Something as simple as a hot plate could provide heat for the reservoir. Maybe I should take a stovetop presure cooker to a shop and have them modify it or something? I know typical pressure cookers have at least one blow-off valve to maintain pressure, though the valve might need to be replaced unless it's designed to maintain an absolute pressure of 2 atm.
