What is the comparison of the advantages and disadvantages of heat exchange using atmospheric pressure equipment, external coils, jackets, and internal coils? Which one has the highest comprehensiveness?
It is recommended to use a schematic diagram specific to the equipment component or the previous one. This needs to be configured according to the specific circumstances.
What’s so special about this? I just want to have a stationary device; when choosing the heat exchange method, what should I consider in making that decision?
I also found such a claim. What is the basis for it? I don’t understand
Considering the heat transfer area, the external coil using round tubes results in the lowest efficiency due to the small contact surface with the outer wall; using semi-tubes makes the welding process more difficult. It is the final effective area determined by the spacing that matters. If the area is similar, it can be better than a jacket; the main advantage is the longer travel distance inside the tube, which results in a longer residence time. Coiled tubes made of round pipes offer the largest heat exchange area as well as a longer residence time, making them the most efficient
Thank you. Are there any materials or guidelines available on this topic? I’d like to learn about it*
I agree with you, but I would add that the outer half-tube serves to reinforce the cylinder.
It depends on what kind is needed; what can be found online is only for reference. If the cylinder has been defined, then the heating or cooling power has also been defined. Good heat transfer performance is required, so internal heating is the only option to consider ； However, the disadvantages of this approach also need to be taken into consideration. For example, what should be done if rusting leads to leaks in the heating medium? Are there any ways to avoid this? Sometimes it is necessary to consider some unconventional methods, and only proceed after evaluating and confirming that they are feasible.
This is easy to handle. What you need is energy savings and improved efficiency; there’s enough space in the container, so it would be best to install a plate heat exchanger there. If the pressure is high, choose a coiled-tube heat exchanger; if the diameter of the container is too small, use a full jacket (though this type of heat exchange does not provide even heating).
My activation reactor works as follows: water is first added, then the temperature is raised to 85°C; after that, the material is added, and the temperature rises further. At this point, I use circulating water to lower the temperature. I would prefer to use a coil or jacket for this purpose, but if that’s not possible, then both a coil and a jacket will be used. The operating pressure is at atmospheric pressure
