    Sep 15, 2021 · A boiler refers to a system in a building that heats water into steam to produce hot water or central heat. While it is more likely that you will encounter problems with low pressure, it is not uncommon to run into issues with high pressure as well.Get Price

  • 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.Get Price
