Will replacing the heat exchanger prolong the life of your furnace?

The heat exchanger in a furnace is the primary component in a furnace. That said, their are circuit boards, motors and other components that can also fail regardless of the age of the heat exchanger. In my opinion, if you can afford to replace the furnace, you would be much better off. The cost of the heat exchanger with labor is probably not too much less than replacing the entire furnace.

Some aluminum alloys such as A413 and A360 would work better as a die casting.Which is a better heat exchanger for residential use, cast aluminum or stainless steel?As a heat exchanger, aluminum could work better than steel because of the temp transfer abilities over steel. Stainless steel will not corrode.


What is Efficiency of shell and tube heat exchanger?

A shell and tube heat exchanger will have two fluids flowing through continuously. The fluid in the tube will typically be the important fluid, the fluid you are trying to heat or cool. The fluid in the shell will then be the fluid that is heating or cooling the the fluid in the tube.Take a steam heat exchanger for example. Steam condenses in shell, while the the fluid in the tube picks up the heat from the steam. And in a perfectly efficient steam heat exchanger, all the heat lost from the steam would be recovered by the liquid in the tube.But nothing is perfect. A little bit of the steam's heat makes the outer shell hot, and that in turn heats the room. Heat is lost from the steam into places other than the fluid in the tube. So efficiency measures how much of the heat lost by the shell fluid makes it into the tube fluid.Efficiency (for heating) = Amount of Heat that went toward heating the fluid divided by the amount of heat that was lost by the heating fluid.So an efficiency of 1 is perfect. For every 1 unit of heat absorbed by the tube fluid, we spent 1 unit of heat from the fluid in the shell fluid.And if the efficiency is 0.9, or 90%, then for every 10 units of heat that the shell fluid lost, the tube fluid gained 9.Sometimes efficiencies are as bad as 40%. In this case for every 10 units of heat lost by the heating fluid, 4 units are gained by the fluid.A slightly different definition of efficiency applies to cooling:Efficiency = Amount of heat lost by the tube fluid divided by the amount of heat gained by the shell fluid.Same story, if the shell fluid gains 5 units of heat, and tube fluid loses 4, then the efficiency is 0.8 or 80%.


How can solar energy become more sustainable?

Solar Energy could become much more sustainable if solar panle could catch a high percentage of energy. Currently they only catch 20% of all solar rays sent to them. It could be more effent if they where heat resent and cold send all light through fresnell lens and that would increase the percentage but currently they arnt. Hope this answers your question check out Enviormental.BlogSpot.Com for more information on this subject.


How does a heat exchanger work in a gas furnace?

shell is the place where hot utilities comes across meets with the tubes which is cold utilities, in order to transfer heat. the area of the heat being transfer depends on how many/much the area of tubes being exposed to the shell hot utilities. the greater the area of tubes being exposed, more heat being transfer. hence, less energy needed in order to heat a big amount of cold utilities. decreasing of the temperature from hot utilities which pass over the tubes, next will be recycled back with others hot utilities/sources of heat.

How much does it cost to purchase heat exchangers?

A heat exchanger is a device that transfers heat from one source to another source efficiently. As for pricing for heat exchangers. The cost varies depending on the type of heat exchanger you want and what device it will be hooking up to. Once you know the type of exchanger and the device that needs it. I would suggest searching online for the best price.


Function of heat exchanger?

There are actually many types of plate heat exchangers, and the YOJO brand has introduced brazed plate heat exchangers and gasket plate heat exchangers. Today is the home of brazed heat exchangers.Brazed plate heat exchangers have no headers, tie rods or sealing gaskets, and the plates are brazed at a temperature of 1100 ° C. During the assembly stage, a piece of brazing material (usually copper, and nickel) is placed between the two plates, the package is compressed, and then baked for several hour.BPHE is more compact and lighter, and the brazing material has the functions of both washer and frame. The intersection between the corrugations of the two coupling plates forms a dense network of contact points, which impart pressure tightness and generate vortex flow, thereby improving heat exchange. In this way, even at low nominal input speeds, the turbulence of the fluid is high, and for low flow rates, the fluid flows from laminar to turbulent.

How much heat does a gas fireplace produce?

Your question is sort of like how fast a car can go- depends on the car. There are different fireplaces- vented, ventless, heat exchanger, etc etc. We had a ventless fireplace with a heat exchanger- and it produced a good deal of heat. Others may be less. You should talk with a gas appliance dealer of your local gas utility for more information.


Do you turn on your heat when your car is overheating?

That can help a little, but the heater core is not a very big heat exchanger, so it won't help much. Better to get a radiator that is big enough to handle the load.


Advantage of shell and tube heat exchanger over double pipe heat exchanger?

**** you.......... pls somebody answer Double pipe heat exchanger consists of two concentric pipes of different diameters.One pipe is for hot fluid and another is for cold fluid.Both may have same flow direction(COCURRENT) and opposite direction(COUNTERCURRENT). Shell and tube heat exchanger consists of a shell in which large number of parallel tubes are present.One fluid hot or cold flow in shell and other hot or cold flow in the tubes. Also in case of shell & tube(S&T) the hot fluid will have more turbulence than in double pipe heat exchanger (HE) since there are no of tubes within a shell the area for convective heat transfer is considerably increased. so these are much more preferredTherefore the rate of heat transfer is greater in shell and tube because large surface area and enough contacting time

because sea water contains large amount of salt in it as impurity. this has much effect on its thermodynamic properties as compared to normal water.


Peace Of Mind When Owning A Pool ?

Owning a pool can be a great or terrible experience. It all depends on you, the consumer. If you go with an aboveground pool, you might have a few headaches, but they're usually easy to deal with. On the other hand, they're not nearly as much fun because you don't have as much room to swim. An in-ground pool comes with a lot more responsibility, but as is the case with most things in life, the more work you put into it, the more fun you can have. Cleaning an in-ground pool is the number one priority. A close second is keeping your pool at the right temperature. After all, what's the point of owning a pool if you can't enjoy it? In order to fully enjoy your pool, you need a pool heat exchanger.Most people are clueless when it comes to a pool heat exchanger. It basically means a heater. These pool heat exchangers, or heaters, come in many different shapes and sizes. Their prices also have quite a range. As far as shapes and sizes go, you can find a triangular tube heat exchanger, a 210k Btu pool heat exchanger, a high fluid velocity heat exchanger, and much more. When it comes to prices, you can spend as little as a few hundred dollars and as much as several thousand dollars. Of course, it's wise to look at the cheaper options first. As long as you can get the quality, go for it, but be careful. It's often the case that pool heat exchangers that cost the least also lead to the most problems.When you buy a high quality pool heat exchanger, you might be spending a lot of money upfront, but you most likely won't have to worry about anything for over a decade. If you have kids who plan on swimming in your pool then peace of mind is more important than anything else. Temperature might not seem like it's a big factor as far as swim safety is concerned, but it has happened before where a kid will jump in a freezing pool at the wrong time of year and the consequences can be severe. It's recommended that you buy a high efficiency pool heat exchanger to avoid this potential scenario.


How to Clean Your Heat Exchanger Properly to Prolong It’s Life?

Cleaning is oftentimes considered to be a tasking job which no one would want to be doing, but there are certain things that we can never avoid. Cleaning does not only involve sweeping the floor, wiping the window panels, and dusting the carpet rug; cleaning also involves getting down and dirty with your appliances- television sets, microwave ovens, and heat exchangers, which are commonly found on electronics like air conditioners and refrigerators. Every cleaning job is incorporated with a few procedures that you must follow through, and the same goes when cleaning your heat exchanger. * Safety first! Unplug the appliance from electrical outlets. Obvious isn’t it? But this is one of the things that a lot of people tend to forget and look over. As a result, a number of accidents have occurred which involves people being electrocuted. * Let your heat exchanger cool down. If your appliance was just recently used, it would be best to allow your heat exchanger to cool down before manipulating it. Once the heat exchanger has cooled down, remove it from the appliance, but remember to use protective gloves. Rubber gloves are not recommended since they cannot take much of the heat. * Wipe the entire tube with a damp cloth and use cleaning agents if you wish. Be sure not to soak it as this might cause the heat exchanger to get ruined. Brush the tube with a nylon bristle brush and make sure to get into the small areas which are a common place for dirt to settle. * If there is hard debris that might need scraping off, a plastic metal scraper is a great tool for you. Slowly remove the debris that might have hardened with time, but be sure not to ruin the tubes of the appliance. * When satisfied and all debris is removed, wipe the whole thing again with damp cloth and follow through with a clean and dry cloth. * Reattach the whole heat exchanger to it’s proper place and be sure that it fits securely. * When testing the appliance to see if it works well, you must stay nearby to be able to observe any unusual occurrences.
