What is the temperature of the superheated steam?
Thread Content
Let me think about what the normal temperature of superheated steam is
In my opinion, this is a difficult question to answer for the following reasons: 1. Whether steam is superheated is determined relative to its saturated temperature at a certain pressure; if it is higher than that corresponding saturated temperature, then it is superheated steam； 2. The temperature of superheated steam under the same pressure also varies depending on the user’s requirements ； It is recommended that the poster specify the steam pressure and the application for this superheated steam, so that others can suggest an appropriate temperature for you.
This is a great question: 1.0 MPa, superheated to 250°C; 3.82 MPa, superheated to 425°C...... Why is it this way and not something else? That is, the study of superheat. For example: Is it possible to superheat 1.0 MPa to 425°C? Please ask a thermal engineering expert to talk about it. Haha,
Not necessarily; it depends on the pressure. Turbines use superheated steam
Superheated steam leads to energy waste; it’s really useful to study superheated steam
Our steam pressure is 8.0 MPa
The pressure and temperature control of superheated steam is worth studying by many technical experts.
How much should the medium-pressure steam be controlled at? Is there a range? Come and learn*.
There is a slight issue with the way it is phrased; the temperature of superheated steam can be high or low. For example, at 4.0 Mpa, the temperature of saturated steam is 250 degrees, while when it is superheated, the temperature can be either 300 degrees or 450 degrees. The key factor is the requirements of the process as well as the capabilities of the equipment. Appendix: Table of temperatures and pressures for saturated water vapor. Pressure in Mpa, Temperature in °C: Pressure Mpa, Temperature °C, Pressure Mpa, Temperature °C. 1.0 181, 1.1 184, 1.2 188, 1.3 191, 1.4 195, 1.5 198, 1.6 200, 1.7 204, 1.8 207, 1.9 209, 2.0 212, 2.1 214, 2.2 217, 2.3 219, 2.4 221, 2.5 224, 2.6 225, 2.7 227, 2.8 229, 2.9 231, 3.0 233, 3.1 235, 3.2 237, 3.3 238, 3.4 240, 3.5 242, 3.6 244, 3.7 245, 3.8 247, 3.9 248
This question is a bit vague. So-called superheated steam refers to steam whose temperature is higher than the saturation temperature at its pressure. The superheat level can be high or low, and is adjusted according to process requirements. Superheated steam is widely used to drive turbines. In general chemical plants, the pressures of superheated steam used for turbine drive are 2.5 MPa, 4.0 MPa, 10.0 MPa, etc., while their temperatures range from approximately 350–380 degrees Celsius, 400–425 degrees Celsius, 500–520 degrees Celsius, etc.; these values vary from plant to plant.
Simply put: when economic benefits are not taken into account, you can overheat as much as you want!
