Some knowledge about heat exchangers
Heat exchangers are often used to heat low-temperature fluids or cool high-temperature fluids, vaporize liquids into vapors or condense vapors into liquids in industrial production such as petroleum, chemical, light industry, pharmaceuticals, and energy.
A heat exchanger can be either a unit equipment, such as a heating device, a cooler and a condenser, etc.; it can also be a component of a certain process equipment, such as a heat exchanger in an ammonia synthesis tower. Heat exchanger is a key unit equipment in chemical production. According to statistics, the tonnage of heat exchanger accounts for about 20% of the entire process equipment, and some even as high as 30%. Its importance can be imagined.
According to the classification of use, it can be divided into heating devices: the heating device heats the fluid to the necessary temperature, but the heating fluid does not change the phase. Preheater: The preheater preheats the fluid and provides standard process parameters for process operation. Superheater: A superheater is used to heat a fluid to a superheated state. Evaporator: The evaporator is used to heat the fluid to a temperature above the boiling point, allowing the fluid to evaporate, generally with a phase change.
