Advantages of medium-pressure steam over low-pressure steam
Thread Content
The enthalpy of medium-pressure steam and low-pressure steam is roughly the same. During the operation process, in some cases people use medium-pressure steam instead of low-pressure steam to heat air to 90 degrees. Is it because of the higher pressure and temperature, which result in a greater driving force and thus less time required? What other advantages are there?

When heating, what’s important is whether the temperature can meet the user’s requirements. A higher pressure results in a higher temperature; as long as the temperature is sufficient, that’s fine. When carrying out heating, it’s not necessarily true that higher-grade steam is better than lower-grade steam
Medium and high-pressure gases can be used as a power source, while low-pressure gases can only be used as a heat source. This is why high-pressure or medium-pressure gases are not used as heat sources; they can first be used for power generation and then as heat sources.
