Supercool liquid and superheated steam

Supercool liquid and superheated steam
Sep 02, 2024
Author: DEAR AST

We often encounter superheated steam and supercooled liquid, so what are supercooled liquid and superheated steam? When heating the liquid in the constant pressure container, the temperature of the liquid is lower than the boiling point at the beginning, and it is all in the liquid state, which is called supercooled liquid. With the increase of temperature, when the evaporation temperature is reached, the liquid begins to evaporate, and the temperature does not change.

At this time, the coexistence of vapor and liquid is in the sub saturated state. When the vapor is completely evaporated, the saturated steam continues to be heated, and the steam temperature begins to rise again. When the saturation temperature exceeds, it is called superheated steam.

At present, there are two types of common condensing evaporators in domestic air separation units, plate fin condensing evaporator and tubular condensing evaporator. Tubular condensing evaporator is divided into three types: long tube, short tube and coil. The long tube and short tube are all in row. The tube is made of red copper and the tube sheet is made of brass. It is generally used in small and medium-sized air separation plants. Coil type is generally used for auxiliary condensing evaporator. Because there is no fixed liquid level in the coil, the heat transfer coefficient is small, so it has been gradually eliminated. The plate fin condenser evaporator is made of all aluminum structure, and the plate unit is arranged in vertical star shape. Its characteristics are compact structure, light weight, small volume and easy to manufacture. It is widely used in large and medium air separation plants. Due to the gradual enlargement of the air separation unit, the heat excha
