About rated steam pressure of industrial boilers

1.25MPa, 12.5kg, which can represent the steam pressure of the boiler. What does this parameter mean in industrial boilers, let's take a look today, and learn the conversion method of steam boiler pressure by the way.

1. Definition of rated steam pressure of boiler

The rated steam pressure refers to the steam boiler pressure at the outlet of the main gas valve of the boiler superheater that must be guaranteed for long-term continuous operation of the steam boiler under the specified boiler thermal efficiency, steam temperature, feed water temperature and rated steam temperature. pressure.

Note:

①. The working pressure of the drum is greater than the rated pressure of the boiler.

②. In fact, the rated pressure refers to the working pressure, which is marked on the nameplate of the boiler. The actual working pressure is generally not allowed to exceed the rated pressure.

2. Conversion of rated steam pressure units

As we often say "kg" of pressure, in fact, strictly speaking, it should be "kg force/square centimeter". If the acceleration of gravity is about 10, then 1kg force/square centimeter = 10 N/square centimeter = 10×10000 N/square meters = 100,000 Pascals

Then 1MPa=1000000Pa=10 kilogram force/square centimeter, which is simply 10 kilograms, that is, 1Kg/cm2=0.1Mpa
