Why is this type of reboiler called a kettle-type reboiler? What does it have to do with Pohang?
The parentheses KETTLE eventually became a pot. . . We don’t know if there’s a story behind this?
Because there is a tower above you; a tower means a kettle, and that’s the definition – without a tower, it’s a boiler
Conventional reboilers are generally vertical; such equipment is commonly referred to as the reboiler bottom and is typically heated using U-tube heating. You can take a look at Figure 6-5 in GB/T151-2014; the owner’s equipment belongs to this type.
Some are established as conventions, some are translations from foreign languages, and some are decided by experts； In short, write it as described in the standards, using a unified name ； Sometimes a unified name can convey a lot clearly.
Reboilers are classified by circulation mode into forced-circulation and siphon types, and by installation style into horizontal and vertical types. Some reboilers are further divided into rising-film and falling-film types depending on the direction of the liquid medium (similar to evaporators). A reboiler is generally connected to a tower. As for why it’s called a kettle-type reboiler, it depends on whether the residue from the reboiler goes to a separation tank or to a reaction vessel (this is my personal opinion; it may not be correct)
It’s just a heat exchanger; there’s no need to worry about its name.
