- Q: important uses of shehh and tube heat exchanger in industry and manifacturing
- They are used in many industries where it is necessary to heat or cool a fluid stream or to simply save the heat that might otherwise be lost. Some examples are: 1. condensers for steam in a power plant. 2. heaters for boiler feed water in a power plant 3. condensers and reboilers in fractionation systems in refineries and petrochemical plants. 4. chillers and heaters in HVAC systems in buildings
- Q: It's a central heating unit, individual to our apartment. We have the thermostat set at 71, heat, fan - auto. Within 1 hour the fan had run 3 cycles 15 min each, and the heat only once for about 10 minutes. Our maintenance staff says it's working properly, but our last bill was through the roof and we now have to manually turn on/off the heat.
- You have what is called a forced-air heater. The air gets sucked into a chamber, heated and then forced via fan to heat the home. The system circulates air after heat has been forced in. This is to purge the system of resonate air. It's annoying but that's why you are cycling so much. Forced-air systems heat instantly but as you can see can be costly.
- Q: How dose the heat pump transfers from cold to hot body ?
- Heat cannot flow from cold to hot under any circumstances. A refrigeration system in an air conditioning unit, when used as a cooling system, uses the expansion of a liquid refrigerant to produce the cooling and exchanges heat with (removes heat from), the circulating air of the building. The refrigerant after doing its work is fully re-vaporised, compressed, cooled and condensed to begin the cycle of cooling again. As a heat pump, the difference in the cycle is that, the compression of the refrigerant gas causes an increase in temperature of the gas. Instead of the gas then being cooled and condensed, the cooler/condenser becomes the heat exchanger between the circulating air of the building and the hot gases. The refrigeration expansion stage is by-passed. The hot gases simply exchange heat with (transfers heat to), the surrounding air as it is circulated and passes over the coils containing the hot refrigerant gases. This cools the refrigerant gas therefore decreasing its pressure. It is then re-compressed and thereby re-heated and begins the cycle again.
- Q: Hey guys i have an air to water intercooler on my car, with the cooling core between the cupercharger and the lower intake manifold. Well the heat exchanger for the system recently developed a small hole. Now the system isn't udner a high pressure or anything, and i can't use anything like radiator stop leak, or it could gump up the VERY thin fins in the core between the blower and lower intake manifold, so does anybody have any ideas on how to seal it? I;ve tryed liquid metal, but either i didn't cover the hole well enough, or its just not working, any ideas?Or do i need a new heat exchanger?
- if few or couple of shell pipes have leaked u can block those pipe but if more u need to change .. inspect it properly and try .
- Q: Hi.. I'm kinda confused with this one... i hope someone helps me here !A dryer operates for 60 hours/week, 50 weeks/year. It exhausts 200 kW/hr of heat and the value of energy is 6p/kWh. A heat exchanger with a 50% efficiency is put into the exhaust stream to recover a proportion of this heat. The installed cost of the heat exchanger is ?22,500. The heat exchanger pressure drop needs a 2 kW fan to overcome it, and the cost of electricity is 10p/kWh. (I have the final answer - but no luck getting it !! - 10 points to the one who gets it right with good enough explanation for me to understand :)Thanks !
- Energy Loss/Yr.: 6p x 200kwh = 1200 x 60 x 50 = 360,000 p/Yr. Exchanger saves: 50% = 180,000p/yr, less fan power costof 10p x ( 50 x 60 x 2) = 60,000 P So 'Payback' is 120,000p/Yr. (less Maint.) How many p/ Pound now?
- Q: i need a engineering ebook on cross flow heat exchanger.

- Q: the formulas of thikness of shells
- The maximum resulting (hoop) stress in the wall of a cylindrical vessel is described by : S = RD/4t S is psi, D is inside diameter , R is the pressure difference psig and t is the wall thickness. All dimensions are in inches. This applied stress would tend to fail by splitting along the side. This is supposing that there are no weaknesses in joints and this does not address the stresses on the heads which can be of various shapes. This basic formula is for thin walls. There are correction curves for unusual thick walled cylinders. ( If the thickness is 20% of the inside radius, the stress is 10% higher.) The codes and standards among other things describe how much pressure or stress to allow for the various service conditions, designs and materials. You then must select a material that can withstand that allowable stress or else adjust the wall thickness, pressure or diameter.
- Q: My furance runs, but the Firebox is damaged with Rust. Furance company told me to get a new one. The furnace runs but I am not using it. Can the box be replaced? and Who would do such a repair if it's possible. Unit is from 95, and has an energy star label on it. Unit is only used for Heat, not hot water.
- If this is a forced air furnace; I'll tell you a secret .....Furnace heat exchanger is probably still under warranty. Problem is that its a major job to replace because most of the time the furnace has to be pulled, completely disassembled, and then put back in place. The contractor is going to make his money either way and its going to be most of the cost of a new one anyway when you take all things into consideration. You will spend all that money and still have a 12 year old piece of equipment that has no warranty on any parts other than the heat exchanger. When you consider that a call to repair any other part is going to be several hundred by the time its done, sometimes its just good economics to replace it when you can buy a standard furnace that has a 10 year warranty on everything and just be done with the problem.
- Q: I haven't been able to light my furnace for a few weeks. My landlord had been in the country of Columbia and didn't return my calls. So I called a furnace repair service to perform a diagnostic on the furnace and they found that my heat exchanger was cracked. When I mentioned the crack in a voice mail the landlord finally responded and claimed that the repairman was lying. When he got back he checked the furnace and claimed that the repairman sabotaged the furnace to charge more money and brought in his own repairman. He told the repairman that he shouldn't check the heat exchanger and just replace the ignition coils. He did, but when he turned on the heater he could clearly see a large crack in the heat exchanger. The landlord says that as long as the furnace lights and stays on that the heat exchanger doesn't matter. I worried about a CO risk, and the landlord wants the furnace to stay on so the pipes don't freeze. Any advice on what I should do?
- This is a tough one and I could go either way. The cracked heat exchanger is the scam of the new millennium perpetrated by furnace companies. On the other hand, if it is truly cracked there is some reason to believe it could cause a problem eventually. Couple of observations: the landlord may be a bit ticked that you called in someone in his absence. Why weren't you able to light the furnace? That would have nothing to do with the heat exchanger issue. Why were the ignition coils replaced? I think I would discuss the whole thing with the landlord and maybe the two of you could get another mutually agreed upon vendor to look at it and assess if there is a CO issue.
- Q: if main steam header pressure is 160psi.Will Pressure regulation at inlet of heat exchanger help to descipate more heat?
- If your steam is 100% pure steam, I can't see how dropping the pressure would help, in fact you loose some energy due to entropy loss by going through the pressure regulator. However, if your main steam is less than 100% pure, a steam/water mix, it might help. If you drop the pressure, at least some of the water would flash to steam and condensing steam has a much higher heat transfer coefficient than flowing water. This may increase the amount of heat transfer in the exchanger.
