boiler assisted steam pressure

What I've learned about steam pressure - Heating Help

Jun 24 2014 · High pressure steam moves slower than low-pressure steam. Isn't that wild? You can see this so clearly on the steam-velocity charts. For instance let's say you wanted to move 200000 BTU/Hr. out of a into a three-inch main. The charts show that at 0-psig the will be moving along nicely at 30.44 feet per second.

Introduction to Steam Distribution | Spirax Sarco

A kilogram of steam at a higher pressure occupies less volume than at a lower pressure. It follows that if steam is generated in the boiler at a high pressure and also distributed at a high pressure the size of the distribution mains will be smaller than that for a low- system for the same heat load. Figure 10.1.2 illustrates this point.
