As an example, when steam is taken from a boiler and the boiler pressure drops, some of the water content of the boiler will flash off to supplement the "live" steam produced by the heat from the boiler fuel. Because both types of steam are produced in the boiler, it is impossible to differentiate between them.

Aug 22, 2017 · How do low pressure steam boilers work. Low-pressure steam heating is just what it sounds like: the steam from the boiler is pushed out to the building at a low pressure as opposed to high. Low-pressure boilers generally stay between 10 and 15 psi and the temperature is maintained under about 300 degrees F.

What Should the Boiler Pressure Be Under Normal Boiler Operation? The pressure for hot water boilers will vary from the boiler system to the boiler system. Most boilers operate with a pressure of 12 PSI. Again, that pressure will differ from one boiler to boiler. Additionally, within the loop, the pressures will vary.

The boiler is firing and making steam pressure. The pressure is rising, and the boiler is in low fire due to low load. The operator control will shut down the boiler to prevent too much steam pressure from building up. However, the operator control is not the same as the boiler steam pressure setpoint. These are commonly confused.

During periods of low steam demand, or when all the use points require pressure-reducing stations, boilers are often operated at substantially less than design pressure. While operating at lower pressure can, in some boilers, provide slightly higher energy efficiency, low-pressure operation also reduces steam quality.
