: : Maybe I should rephrase my question.I am trying to say as far as being an operator accustomed to a plant that runs 150, and going to a plant that runs 800. I understand what you are saying, but I am looking for differences as far as taking swings...the way the boilers behave...that kind of stuff...things you would do with an 800 lb system that you would never do with a 150...or vice versa. Hope I am being clear. Thankyou for your kind response, tho...:)

: Hey. :) Curious...can anyone share with me the difference between operating boilers at say....150lbs and 800lbs....pressure, of course. Just curious what the big difference is, and any different precautions or strategies...would appreciate any info...

: alot! temperture for one is much greater. volume changes,ex: the more pressure aplied to a pound of steam the less space it occupies. flow rate changes. your boiler auxilliares may have to change, feed pressure, releif valves, limit switches, may have to replace valves and lwco due to pressure ratings.
