NBBOKLPOB low pressure - Ohio
Apr 27, 2015 · The definition of low and medium pressure is somewhat discretionary. For the purposes of this discussion, low pressure shall apply to boilers up to 150 psig. These boilers are typically used in space heating applications where the percentage of return condensate is high. Medium pressure boilers fall in the range of 150 to 650 psig.

Water Handbook - Steam Purity | SUEZ
Low-capacity, low-pressure boilers (usually fire-tube boilers) rely principally on simple gravity separation of steam and water. At 200 psig and saturation conditions, the density of water is 115 times greater than that of steam. Because the steam is typically used for heating, steam purity requirements are …
