Heat loss due to steam pressure reduction without temperature drop
Thread Content
Can 3.6MPa steam achieve pressure reduction without a temperature drop? By checking the enthalpy values, it was found that the enthalpy still increases after depressurization. . . . . Is there any heat loss, and how is it calculated?
Normal pressure reduction involves a small amount of energy loss, which occurs at the throttling device; steam at lower pressure levels has a higher phase change enthalpy. I hope this is helpful to you!
If it is superheated steam in the first place, then its temperature certainly will not drop (ignoring heat loss). If that 3.6 MPa steam is saturated steam, there are also two possibilities: whether the temperature will drop depends on its dryness and the pressure after depressurization; knowing both values is necessary to determine whether a temperature drop will occur.
