Kettle-type re-boilers are very simple and reliable. A re-boiler is equipment which is installed with the distillation column and its purpose is to convert the liquid which is provided by the bottom tray of the distillation column into vapours. These vapours are then returned to the distillation column.
Advantages
*High Vaporization.
*Easy to maintain.
*High level of vaporization makes it prone to fouling.
*Simple in Design.
*Pressure drop in this is lower so suitable for vacuum services.
*Liquid is totally converted into vapour so when you need a high *vaporization rate then it is suitable.
