What are the potential hazards of introducing both circulating water and steam at the lower outlet of the reactor jacket?

The practice of introducing both circulating water and steam at the lower outlet of the reactor jacket may pose certain risks. Firstly, introducing circulating water and steam simultaneously at the lower outlet of the reactor jacket may cause sudden changes in temperature and pressure, thereby increasing the risk of the system getting out of control. Secondly, the simultaneous entry of circulating water and steam at the lower opening of the jacket may cause local overheating or condensation, leading to equipment failure or other safety issues. Under normal circumstances, the operation of a reaction vessel should be carried out in accordance with relevant safety regulations and operating procedures. If there are specific operational requirements, it is advisable to consult professional engineers or relevant departments to ensure the safety and feasibility of such operations. Specific regulations may vary by region and industry; it is recommended to consult relevant safety standards and regulations to understand the more detailed requirements. .

\"Foam coalescence\" can occur, leading to vibration that damages the equipment. When a steam boiler is shut down for maintenance, if the check valve fails and the valve does not close in time, steam returning to the feedwater pipeline can easily cause a phenomenon of \"steam-water slugging,\" leading to severe intermittent vibrations in the pipeline; in serious cases, this can result in the cracking of flanges and pipes. In the past, in public bathhouses, steam was directly introduced into the large tanks to heat the water, which caused a lot of bubbling noise. If the pool is not open, it might all get torn apart. A tubular heater can be used to heat the circulating water with steam to the specified temperature, after which the heated water is fed into the reaction vessel. The hot water at seventy or eighty degrees after steam condensation is directly returned to the circulating pool.

Are there any explicit regulations regarding this in terms of specific aspects?

Please look up an introduction to water hammer. Doing this this way is also meaningless

Yes, this approach is not appropriate. In the workshops of some small companies, the heating method used for reaction vessels is quite outdated; from the perspectives of temperature control and intrinsic safety, it is unsuitable. But what I need right now are the regulations written on paper – I just want to take a look and learn more about them. I’ve looked around these days as well, but I still haven’t found it.

Such operations can easily cause localized overheating or overcooling of the equipment, leading to damage over time. In addition, attention should also be paid to the anti-corrosion parameters of circulating water.
