I’m seeking help regarding **the gas velocity of water vapor under negative pressure**
Thread Content
A newcomer is seeking advice from experienced professionals regarding three-effect evaporation: the first effect operates at atmospheric pressure, the second effect at -0.05 MPA, and the third effect at -0.09 MPA. What should be the steam velocity in each effect?
The gas velocity only needs to meet the pressure drop requirements.
For the evaporation chamber, the requirements for gas-liquid separation are generally the key factor; there are standards for designing gas-liquid separators, and calculations are carried out with reference to these standards. However, in actual design, consideration is also given to whether the material tends to form bubbles; if it does, the diameter should be increased appropriately
