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.
