Thanks for the info, here are some clarifications:
1: The liquid to be boiled; The starting temp will usually be about 160 F, and boiled for a maximum of 2 hours. That being said, I would like enough steam to heat and boil from 50 def F to be safe. It needs the capability to raise the temperature 3 degress F per minute. So from 50 deg F to 212 deg F should take about an hour.
2: The heating from 50-180 is a seperate vessel or unit. This vessel should have the same heating properties as the boiling vessel. So I guess in effect doubling the requirement.
I was hoping to acheive this with an operating pressure of 15 psi (low pressure).
PS. How does pounds per hour correlate to BTU's. I think I read that 34.5 pounds equalls one HP? Should just buy a book huh? :)
Thanks a lot!!!!
