Shell And Tube Heat Exchanger

Shell and tube heat exchanger pressure vessel kettle type heat exchanger kettle type reboiler.
A kettle reboiler is a heat exchanger used in a chemical distillation process. This shell-type exchanger has a large open boiling surface much like a kettle on a kitchen stove. Typically, it is the vessel at the bottom of a distillation column. The vessel receives condensate from the separation tray above it and returns vapor to provide the heat energy to the column. The design of a kettle reboiler allows for a large transfer of heat on a continuous basis.
A reboiler is an 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. A reboiler is essentially a heat exchanger. Kettle type reboiler is one of the most common types of reboiler used in industries.

Product Detail

Working Principle

It consists of tube bundles, the tube bundles are supported by a support plates. The structure of tubes can be either straight tubes or U-shaped tubes. The straight tubes are more versatile they make the cleaning easier. The U-shaped tubes have an advantage that they allow for thermal expansion without putting the rest of the exchanger at risk.
