Please have a thorough discussion on the potential harmful consequences that can arise if the tubes in a reboiler experience dry burning How to avoid it in actual production?
The main impact of dry running in a reboiler is on the material of the furnace tubes. When the temperature exceeds what the tubes can tolerate, slight changes occur in the crystal structure of the tube material, which leads to the failure of those tubes; in severe cases, tube rupture may occur. If there is no flowing medium to absorb the excess heat, all of the heat will be absorbed by the furnace tubes.
If dry burning continues for too long, the local temperature will rise significantly, causing the furnace tubes to deform and leak, which can easily lead to fires and force the installation to shut down. Ensure that the furnace tubes are filled with the medium to absorb heat; use the observation hole to monitor the burning condition of the furnace. It is prohibited for the flame to burn the furnace tubes, as heat should be transferred through thermal radiation
