The function and principle of flash tank

Flash is high pressure of saturated water into a low pressure in the container, due to the sudden decrease of the saturation pressure water into the container under the pressure of saturated steam and saturated water. The boiling point of material is increased with increment of the pressure, and decreased with the decreasing pressure. This allows high pressure high temperature fluid after decompression, reduce its boiling point, into the flash tank. Flash tank's role is to provide fluid rapidly vaporized and gas-liquid separation of space.

1, flash is a high pressure of saturated water after entering a low pressure in the container, due to the sudden decrease of the saturation pressure water into the container under the pressure of saturated steam and water saturation.

2, the boiling point of material is increased with increment of the pressure, and decreased with the decreasing pressure. So that high-temperature high-pressure fluid after decompression, reduce its boiling point, into the flash tank. At this point, the fluid temperature above the boiling point of the pressure. Fluid boiling evaporation rapidly in flash tank, and two phase separation. To fluid evaporation equipment not flash tank, but the pressure reducing valve. Flash tank's role is to provide fluid rapidly vaporized and gas-liquid separation of space.

3, when the water is heated under atmospheric pressure, 100 degrees Celsius is under the pressure of the liquid water could allow the highest temperature. Reheat cannot raise the temperature of water, but only turning water into steam. Water before heating up to the boiling point in the process of absorbing heat is called "sensible heat, sensible heat or saturated water. In the same atmospheric pressure will be needed for saturated water into steam heat is called "latent heat". However, if the heating water under pressure, then the boiling point of water is higher than 100 degrees Celsius, so would require more sensible heat. The higher the pressure, the boiling point of water is high, the higher the heat content. Pressure is reduced, part of the sensible heat released, this part of the excess heat will be in the form of latent heat is absorbed, causing some water is "flash" into steam.
