Classification of heat exchangers
Sep 10, 2019

Heat exchangers can be divided into:

 

(1) heater: the heater is used to heat the fluid to the desired temperature. The heated fluid does not undergo phase change during the heating process.

 

(2) preheater: the preheater is used for preheating the fluid to improve the efficiency of the whole process unit.

 

(3) superheater: superheater is used to heat saturated steam to reach the superheated state.

 

(4) evaporator: evaporator is used to heat liquid and make it evaporate.

 

(5) reboiler: reboiler is a special equipment for distillation process. It is used to heat the condensed liquid and make it vaporize again.

 

(6) cooler: the cooler is used to cool the fluid to the desired temperature.

 

(7) condenser: the condenser is used for condensing saturated steam to release latent heat and condense and liquefy
