Regarding the installation height of self-circulating kettle reboilers
Thread Content
A kettle reboiler is different from a thermosyphon. I would like to ask the experts: is it sufficient for the installation height to ensure that the normal operating liquid level of the tower is slightly above the evaporation tube bundle of the kettle reboiler (so as to keep the tube bundle fully submerged)?
It is necessary to keep the liquid level above the height of the overflow weir of the kettle reboiler.
Ensure there is sufficient gas space above the reboiler.
To ensure the safety and efficiency of the evaporator, its installation height should be such that the upper part of the heating tube bundle is at the same level as the lowest controlled liquid level in the tower bottom
The pressure difference generated by the difference between the lowest liquid level in the reactor and the liquid level in the reboiler should be sufficient to overcome the pressure loss associated with flow through the pipeline at the bottom of the reactor to the reboiler, under the design flow rate on the process side of the reboiler. Furthermore, the reboiler liquid level must be able to cover the tube bundle.
Agreed, O(∩_∩)O Thanks
