Important: This is essentially the same as a 'from and at' rating, so using feedwater at lower temperatures and steam at higher pressures will reduce the amount of steam generated. In practice: A BoHP figure of 28 to 30 lb / h would be a more realistic maximum continuous rating, taking into account the steam pressure and average feedwater

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-pressure system for the same heat load. Figure 10.1.2 illustrates this point.
