Electric boiler with highly variable pressure
Electric boiler with highly variable pressure
(OP)
Hello,
The lab I do work for has asked for a boiler system that will create steam at anywhere they choose from 60psi to 1400psi, for some experiments they would like to run. Ideally, it would have an electric boiler, as it will be working in a lab environment. I have limited background in this area, and I was hoping you guys could answer a few questions for me:
1) Is it even possible to build a boiler system with that much variation in the operating pressures?
2) My research seems to indicate that electric boilers generally top out around 500psi, although this thread (http://www.eng-tips.com/viewthread.cfm?qid=288304) names a few companies that may be able to produce it. Still, a boiler designed to run at 1400psi will be hilariously overdesigned when running at 60psi, correct?
Thanks for your help. If the answer is "It's just not possible," then that's probably a good thing. I'll have to talk them into lowering their requirements somewhat.

Good luck with your search.

You won't get one set of controls which will handle that whole range, though. That's a tremendous range in volumetric flowrate. You'll need multiple control valve trims and flowmeter ranges, assuming you need to measure how much steam you're generating.

The organization I used to work for has a steam testing facility in Philadelphia that may meet your needs. I know they've performed testing for several other government organizations in the past and some private concerns that were building equipment for the USG. If interested I can put you in contact with the right folks.
RE: Electric boiler with highly variable pressure
then I would recommend a boiler from 0 to 600 and a second 600 to 1400. being that a lower pressure boiler is cheaper to run.
now that you say 600 to 1400 gets more real.
