The basis of vacuum evaporation - Environmental engineering

Vacuum evaporation is a technique which is characterized by transforming liquid effluent into two flows, one of high quality water and the other comprising a concentrated waste. The water obtained is of sufficiently high quality to be re-used, whereas the waste can be concentrated, even reaching almost total dryness.

High Pressure Boilers - Features and Advantages

A boiler is called a high pressure boiler when it operates with a steam pressure above 80 bar. The high-pressure boilers are widely used for power generation in thermal power plants. In high-pressure boiler if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

Why Does Humidity & Wind Speed Affect Evaporation? | Sciencing

Partial pressure influences the effects of wind speed and relative humidity on evaporation. The partial pressure of water in the air relates to the amount of water that is contained in the air. When a water molecule that returned to water replaces a water molecule that evaporated, evaporation stops, regardless of wind or relative humidity.
