As the title suggests: What is the working principle of an external heat exchanger?
The external heat exchanger is installed outside the regenerator. The regenerated catalyst is drawn out from the regenerator’s dense-phase bed and enters the external heat exchanger, where it heats the feed water; once the water vaporizes, the heat is carried away. After cooling, the catalyst returns to the regenerator. This method of heat removal is known as external heat extraction.
It is a disguised “heat exchanger”.

It’s essentially a large heat exchanger that uses a catalyst and deoxygenated water for heat exchange, thereby cooling the catalyst while heating the water into steam!
Generate steam by absorbing heat from the catalyst
