I work at a waste water treatment plant. We use heat exchangers to warm digesting sludge. Heat's provided by burning methane produced in the digesters. We have generators, but they are nonfunctional, so excess methane is burnt in a waste flare. Water is heated to ~170/77 in the boiler, goes into the HEs at about 150/66 to get the sludge up to ~98/37 to accommodate mesophilic bacteria. Control is provided by a bypass valve on the water side.
I have a 6 year tenure in coal and natural gas turbine power plants, cleaning supercritical boilers and system components (oil coolers, feed water heaters, cooling towers, condensers, plate heat exchangers, etc. 1 year of demolition and disassembly of commercial and industrial HVAC systems, and have been a scaffold builder during my total 8 year tenure as a laborer. Looking to switch to the pipefitters union, and going to school for HVAC to boost my resume. Unfortunately my work experience wasn’t enough, at least that’s a possibility. The decision to hire is based on a vote of 30 fitters and business owners, so I have no way of knowing why I didn’t make the cut during my last interview. Your videos are helping me to organize my elevator speech for my next interview 👍 thank you!
Like José Manuel below, when I lived in Alberta I would commonly purchase mulitpass shell and tube exchangers, plate and frame exchangers, giant fin-fan exchangers for a giant SAGD (oil) plant. Awesome pieces of equipment.
Most commonly used in vehicles i.e. radiators. I worked as a machinist in an industrial heat exchanger mfg facility in Beaumont, TX. for a few years after the first Gulf War. Some of the metals we used in the mfg process were inconel, monel, hastelloy, copper nickel, stainless steel, brass, copper, titanium and most commonly steel.
Such a great and explanatory video. Thank you! Usually in dairy industry (basically milk) the usual heat exchanger is plate heat exchanger. This heat exchanger is used for pasteurization because it’s able to achieve the demanded temperature really quick and the microorganisms get thermal shock, without affecting the organoleptic characteristics. Also the patterns create turbulent flow as shown, and increases the surface (approximately by 40%) so the heat transfer increases.
Great video. Typically when flow goes into the shell side of an exchanger, it enters the bottom to keep air pockets out. I work with literally dozens and dozens of these. There’s no end to the services.
I work in the pharmaceutical industry and we use finned tube heat exchangers in Air handlers for heat and cooling, also shell and tune heat exchangers for clean water generation... great explanation 👌 👍 Keep the great videos coming! 🙂
Awesome vid!!!!!! I totally love all of these stuff.... I live in the wild Alberta and heat exchangers are a sacred matter!!! Thanks a lot for sharing, your vids make this world a better place!!!
I'm a tech for a Fluid Chillers Corporation. We recently built a low temperature chiller for Dow chemical. It had a boil off coil in the suction accumulator. The liquid line runs through the accumulator so the cold suction is transferred into the boil-off coil. Quite often my suction pressure will be in a vacuum on a low temp chiller. I'm curious if the boil-off coil will raise my suction pressure. The chiller for Dow was not an ultra low temperature -70F so I didn't get to see how the boil-off coil would affect the suction pressure at ultra low temps.
I was doing the work of heat exchangers,boilers since twenty five years. Now I am in kerala.I was in Mumbai,Saudia arabia in this field for many years.I have made new ones Re tubed many heat exchangers and boilers(horisondal,vertical and U bundles).
An old 'get you home trick' to solve a leaky radiator was to put a raw egg in the coolant. Once boiling the white was thick enough to block the hole but would not block the pump. My brother, head boy of his school but hopeless at all things mechanic got a leak in his petrol tank.... The funniest bit was when he called the garage once the car had stopped completely. "What's wrong with it mate?". "I think there may be egg in the carburetor" came the reply.
A customer has a central chilled water and steam plant that runs continuously year-round. Domestic hot water is created from the steam plant. The estimated hot water needed annually is 23,267 MMBTUs. The proposed energy conservation measure is to install 4 water source heat pumps to heat the domestic hot water. The proposed equipment will create an additional 145 tons of chilled water while using the heat rejection loop to heat the hot water. How much energy savings will be associated with this measure? Baseline System Chiller plant - 145 tons to be replaced annually. 0.75 kW/ton Boiler Plant - 23,267 MMBTUs to be replaced. 76% plant efficiency Proposed System 4 WSHP - 145 tons total, 1.848 kW/Ton, condenser 2.656 MMBTU/HR If you agree there are savings, how much energy will be saved? Mention any assumptions you are making. Feel free to look up any metric conversions (i.e. kWh to MMBTU, etc).
Charlie, we'd be happy to take a look at your customer's application and see if there are savings to be had. Feel free to reach out. www.superradiatorcoils.com/contact-us
I have seen heat exchanger in. Nuclear desalination demonstration plant in kalpakkam ,Msf plant used to convert steam to water( Hp steam): which is used to keep entire system in vaccum,lP heat exchanger for(to increase salt water temperature) to get flash in vaccum
i work in aquaculture, marine fish hatchery. we have quite allot of plate heat exchangers. they are a huge pain to disassemble, clean and reassemble. you have to be very careful with rubber gaskets, so they dont leak. salt and metal. corrosion everywhere. im not an engineer, but i wonder if they can be made out of some other material rather than metal?
The heat transfer properties make metal the best suited, corrosion is a problem though. There are lots of coatings that can be applied to reduce this but these usually come at a compromise of slightly less efficiency but longer service life. Perhaps a heat pump for the thermal transfer and a separate system for water cycling
I dont know about salt, but as an hvacr guy I once did some work for a guy that had a small trout farm. Ended up building a 500 gallon reservoir tank with pipe coiled inside. the water circulation pump would dump into the tank while the pipe was connected to a refrigeration system.
Plate and frame heat exchangers are also commonly used in chiller plants where you don’t want to mix the cooling tower water (which is open to the environment) to the chiller equipment which can cause fouling or other issues. Some commercial buildings even use them during cooler days to allow the cooling tower water to directly cool the air moving through the air handlers and bypass the chillers completely which saves energy. The heat exchanger in this case prevents the cooling tower water from contaminating the chilled water loop that cools the building. This configuration is known as a water-side economizer or chiller bypass economizer.
As far as I know, at work we use plate heat exchangers for our HTST processes, finned tube in our evaporators and condensers, and the tube and shell for i believe our CIP lines.
I enjoy your videos and learn something new every time i watch them In the HVAC/Refrigeration industry there are a lot of questions for Sound and to a lesser extent vibration. I wonder if you would like to look at this topic
@@EngineeringMindset Cooling towers in Canada but overseas where the cooling water is warmer, we use typically 4 huge plate and frame heat exchangers in line, for better control of temperature. The water/gas cooler moves around 5-7 million m3 of water an hour so pretty big in size. I work in UNIPOL gas phase, pretty cool design!!!!!
Most heat exchangers I've seen were on refrigerators and automobiles. I've been inside a lot of HVAC systems and I've seen chillers [and brine lines] in arenas. Industrial refrigeration would be a great topic for a video. I've heard that Kangaroos lick the inside of their forearm to use evaporative cooling to cool their blood and use their circulatory system as a heat exchanger.
The body's circulatory system is also a heat exchanger with the very advanced mechanism of being air or liquid cooled and has a variable pressure pump, on demand.
very educational video..congrats.. can you do also a video sir about how to proper adjust a hand expansion valve on evaporator for ammonia double stage refrigeration..thank you and godbless
You didn't talk about one of the coolest heat exchanger designs, the coil wound heat exchanger! Commonly used for multi-path cryogenic applications such as the main heat exchanger for cryogenic air separation plants.
I’m pretty sure on the shell EX that those so called baffles are supports so the tubes don’t lay over. The baffle plates would be on the bell end on in he channel head
I have seen this type of heating Exchange the hotel i work at which has a boiler system and i looking to learn more about this and Become a Stationary Engineer
I want to buy this system from you and should be installed our exhaust generator finally result we want air condition or cool air. so ,please help me for buy from you, how can i contract with you
I love how he tells us to comment where we've seen heat exchangers like we're 3 year old children who don't know he's just doing that to increase views and suggestions.
Hi! industrial laundry tumble dryers use finned tube heat exchangers, and it often leaks😂 but.. pls tell me does anyone using steam for home heating? its hot af. unbelievable for me (living in Russia)
What's happened to the unwanted thermal energy that got rejected into our atmosphere? that's mostly causes climate change and global warming with severe weather conditions
Greta video yet again. There is a error maid in the flow direction in som of the illustrations, witch deceess the effeciency of the heat exchanger. Please redoo the illustrations to spred out the best nollege to peaple 🙂
I hate people calling it heat exchanger. Heat is never exchanged, it is always transfered. An exchange happens in both directions. Heat only transfers from one side to the other and never both ways simultaneously.

Dear Paul sir I think we can also use this in a extreme IC engine which are used in heavy duty generator .... I IN MY POINT OF VIEW
Yeah good idea, we need to cool the engine and we can also make use of the waste exhaust heat.
thankyou sir the waste hot air can be used in making the fuel's temperature hot, by which the combustion process will be more efficient .
