Steam temperature issue at 3.5Mpa
Thread Content
A certain medium is heated using steam at 3.5 Mpa. If the temperature of the steam at 3.5 Mpa is around 270 degrees, then is this 270-degree temperature the temperature under a pressure of 3.5 Mpa? If 2 tons of steam are used, is the temperature of these 2 tons of steam also around 270 degrees? Thank you; please explain this to me if you understand
This steam is superheated steam; the saturation temperature of steam at 3.5 MPa is 242 degrees. 2 tons of steam were used, so the temperature is naturally 270 degrees. Don’t you have a way to lower the temperature?
Saturated steam at 3.5 MPA cannot reach 270 degrees; it must be superheated.
If 0.2 tons are used, is the heat value of that 0.2 tons of steam also 240 degrees?
0.2 tons were used; what does this steam turn into? Water, or does no phase change occur? If there is a phase change, the heat is the enthalpy of the superheated steam, plus the sensible heat resulting from the change in water temperature.
“If the temperature of steam at 3.5 Mpa is around 270 degrees, well, such assumptions can lead one astray; if one’s knowledge about steam is insufficient, it’s better not to add one’s own interpretations, as that will only mislead people. Posting the original question increases the chances of it being resolved
You have confused a concept here; the unit of heat is the joule. In other words, the amount of heat cannot be measured using temperature. At around 35 kilopounds of force, the temperature of saturated steam is approximately 240 degrees, and this has nothing to do with its mass. It can only be said that the greater the amount of saturated steam, the more heat it carries. First, clarify these concepts.
