Walt and the List:
According to Properties of Saturated Steam data from the 1991 Brooks
Instruments catalog, saturated steam temperatures for various pressures
(psig) will be:
PSIGTemp (F)
0.0 212.00
20.3259.28
40.3287.07
60.3307.60

Steve,
My fuzzy logic (Balvenie fortified) seems to think there is some sort of
temperature gradient, otherwise all the water would flash to steam unless the
increasing vapor pressure keeps the water from shifting phase, requiring
greater heat input per unit to increase the temp to make more
Walt,
I believe that your statement the increasing vapor pressure keeps the water
from shifting phase, requiring greater heat input per unit to increase the
temp to make more steam is correct. As the boiler continues to be fired the
temperature and pressure both rise until the safety blows.
