[0002] A flash tank is a device used to quickly convert high-pressure saturated water into saturated water vapor and saturated water when the pressure is reduced. When high-pressure saturated water enters the flash tank, the boiling point of the water decreases due to the sudden drop in pressure, causing the water to boil and vaporize rapidly, and produce saturated water vapor and saturated water. It is an important energy recovery and processing equipment, widely used in thermal power generation, geothermal power generation and other fields.
