What are the provisions for expansion of shell and tubes?
None, it is a fixed design. You can remove or block tubes to reduce the heat transfer design
Are the pressure equilibrium between the primary heating coolant and the target coolant the same inside the loop to prevent pressure buildup?
can you make a video on how to select a compressor for a new system. please
Bro I want a vu meter connection
Used to design the piping to these pieces of equipment as well as all equipment found on oil (etc) refineries / chemical plants etc... did so for decades. You bring back memories. When installed, there is a fixed end and floating end for these exchangers ... the floating end is the opposite end to the header and slides on its supports as it expands.
The piping needs to be designed with this and all stresses borne in mind.
This is very helpful and right on time, because I work with these heat exchangers right now! Many thanks.
OMG 😱
Finally
I needed it!!!!
Thanks a lot
Nice to see "shell and tube" type of heat nowdays! They have evolved over the years and a better understanding is achieved with this presentation particulary on the hydrodinamics of shellside flows. 👍
For additional information: In liquid-to-liquid applications it is prefered to put the "dirty" water into the tube side since cleaning or plugging tubes is much easier than on the shell side. Some reasons to put multiple passes of the tubes include space as well as increasing fluid velocity for better heat transfer efficiency. In a recent application we put replacement chillers in with a 2 pass condenser rather than the current 1 pass to save on piping space on the other side of the room. Tubes can be "enhanced" internally and/or externally to increase heat transfer efficiency using fins or internal rifling.
Hi bro
which is better: water inside the tubes and steam on the casing side, or steam in the tubes, and water surrounds the tubes on the casing side
Nagledali smo se ovih i ovakvih izmjenijivača ....hvala.
Thanks for the videos!
🥃🥃🍺🍺🍺🎳⛳
Very well explained. Thank you.
Great video!
Great presentation
I did water treatment on cooling towers 20+ years ago. I would’ve progressed into chillers & boilers more if I would’ve stayed with the on but my trainer was just to big an A-hole, I grew to despise him, & I feared becoming him. He made a lot of money but it doesn’t make up for being as big a tool as this guy was.
Lol, many tools in this industry.
The world is FULL of tools, unfortunately…….
Great video :)
very nice explanation and animations
thanks for video
Wow that is good for watching
I'm retired so no longer teach this type of information. But still enjoy seeing it.
Great to hear!
I'm still young but I failed the job interview
@@Goat.phomator666 well if you're still young, study and try again.
Was that the POS test?
@@Goat.phomator666 keep trying👍
Thanks!
As a marine diesel mechanic, I'm very familiar with heat exchangers, since you can't place a radiator inside an engine room. Thank you for this lesson.
Hay man
I'm marine too , but I still study, so can I ask you some questions
Here in the US the Double Pipe or Tube in Tube heat exchanger is also called a Plate and Frame heat exchanger.
Is this the sistem that is used in regular combo (2 in 1) washer-dryer machines (not the ones with heat pumps) for condensation of the moisture drawn by the hot air from the clothes?
If so, does anyone know how exactly it uses the cooling water? Does the machine draw cold water continuously? Does it empty and refill the shell after every set amount of time? Or does it have a temperature sensor inside the shell that governs either the refilling of the shell or the debit of cooling water running through the shell?
I want one!!!
Requesting topic. Air break system for a bus or truck transportation
thanks
Steam locomotives use similar to Shell and Tube Heat Exchangers. It would be nice to make a video on steam locomotives :)
The 6.9L and 7.3L IDI international Harvester Diesel engines used in Ford pickup trucks from 1983 to 1994 used these heat exchangers as oil coolers.
At 4:00, the animation shows the milk being warmed starting from the outlet side and not the inlet side. Is there any reason for this, since warming it from the inlet side would be more efficient thermally? Love your videos BTW.
Thank you for perfect explanation.
Very helpful
Could you please in your video talk about PID controller as well
proportional integral derivative
I work in a coal power plant and this its also use after the vapor does the work in te turbine it goes to 5 of those to heat the feeding water
Long time No see...
This type of heat exchanger is also used in PWR type nuclear power plants.
Plz make a video on how ammeter works plz
May I ask sir if heat exchanger can boil water?
Might be good for cheaper desalination as well. Pump filtered sea water into the header, heated to evaporation in the tubes, and back to the header with one outlet for heavier brine and one outlet for water vapor to be condensed and pumped out to the water supply. Seems way less expensive than reverse osmosis. Especially with 8 degree C temp difference between boiling points.
The problem is that heating water to boiling point + the latent heat of evaporation is expensive and while the heat can be recovered somewhat in the condenser there is always inefficiency. While reverse osmosis doesn’t need to put as much energy into the water and you already need pumping already.
Instead of using straight Baffles use screw type Baffles to rotate the flow of water 360° to the heat exchanger tubes inside of the shell to increase the efficiency of heat exchanger
Okay just recommend me some best expanders buddy !!!!!!🙌
How do you edit you're videos
💛💛💛💛💛💛💛💛💛💛💛💛💛
👏👏👏👍
You showed but did not explain, in addition to the U-Tube type shell-in-tube heat exchanger, the floating tube sheet type. You may want to also explain that type.
What is the boiler design that uses a spray of water to create instant, high pressure steam? I can't remember what it's called and my googling has not been productive!
Flash steam boiler.
@@webtoedman sweet, thanks!
You have sale of Thailand
How can I know which to put hot or cold fluid in shell or tube?? 😅
I think it depends on the fluid tube
*type
Considering these important features of the tube bundle in an exchanger, following fluid services are better suited for the tube side.
Fouling or corrosive fluid service is kept on the tube side, since mechanical cleaning of the inner tube surface is easier.
It is cheaper to replace corroded tubes, than the shell cover. Hence corrosive service must be kept on the tubeside.
High pressure fluid is also kept on the tubeside, since tubes with higher pressure rating are cheaper than the shell with high pressure rating material.
Toxic services are kept on the tubeside to increase their containment.
Fluids where you have a low allowable pressure drop are also kept on the tubeside.
Cooling water is generally kept on the tubeside, because it tends to corrode carbon steel and form scale.
See our new video on how to build mechanical versions of electronic circuits? Watch here: czcams.com/video/Zv9Q7ih48Uc/video.html
isn't this video a re-release, but shorter?
And specifically made just for shell and tube hex, so that people can find exactly what they need, when they need it
Then cool reference :)
