Low pressure boilers are steam or hot water boilers that have a maximum pressure of 15 pounds per square inch for steam and a maximum of 160 pounds per square inch for hot water. Low pressure boilers are usually used for heating purposes.Continue Reading
Boilers provide steam or hot water energy to operate heaters, kitchens, laundry facilities, and manufacturing plants. They may operate under either high or low pressure and can be labeled as high- or low-pressure either by the pressure used in their design or the pressure under which they operate. Safety settings on the boiler are normally the same as or less than the design pressure. The operating pressure of the boiler, which is different than the design pressure, is the average operating pressure of the boiler. A low pressure boiler has both a lower design pressure and a lower operating pressure.
Steam quality is determined based on the moisture level of the steam. Low pressure boilers typically produce a lower quality steam that contains more water in liquid form than does high-quality steam. Wetter steam can cause more damage to equipment due to erosion, especially to metal parts, and can cause fittings to loosen. Lower pressure boilers require more steam to produce heat.Learn more about Heating & Cooling
