Product Description:

1.Product Description:

Re-boiler is ahigh-efficient heat exchanging equipment used in alcohol, solvent, foodferment, pharmaceutical, petrochemical, refrigeration, organic chemistry, metallurgicalindustry, suitable for convection heat transfer of liquidtoliquid,gas to gas,gas to liquid. Re-boiler is made of carbon steel and stainless steel.

2.New Technology Description:

Five-ColumnThree-Effect Distillation Process

Our company designs and manufactures latestFive-ColumnThree-Effect Distillation equipment.This new process is promoted on the basisof traditional five-column differential-pressure column and mainly used forsuper-fine alcohol production.

The key of this process is the heatingmethods,the steam heats one column directly andtransfers theheat to other 4 columnsto achieve three-effect thermal couplingand energy-saving effects.

In terms of electricityefficiency, it can save 50% electricity and avoid the repairing ofcirculating pumps and also extend the working life of there-boilers.

Double-Mash-Column Three-Effect DistillationProcess

This process applies to the production ofgeneral-grade alcohol& fuel ethanol, and it was awarded Chinese nationalpatent, it is the onlysuccessfulapplicationof doublemash column & three-effect in the world,whichproduces general-grade alcohol.

This process is composed by mash column,rectification column and composite column. The composite column functions asmash column and rectification column.

The key of this process is the heatingmethods: the steam heats one column directly andtransfers the heat to other 2 columns to achieve three-effect thermal couplingand energy-saving effects.

The advantage of this process is energy-saving;itsaves over 40% steam

Q:My neighbor went to turn on their heat last night and it clicked on okay but a moment later their smoke?
Hopefully something like a oily substance got coated on the heat exchanger and caused some smoke. Lat us know what the tech findings was.
Q:What is a double tube plate heat exchanger?
On the market less domestic brands, expensive, generally more than 100,000 yuan, imports can be hundreds of thousands, in line with the new version of GMP regulations, although expensive, but decided to its broad market.
Q:Consider a stream of low pressure air that passed through a heat exchanger at the rate of 3.4 lbm/min.The air absorbed 1.15kJ/min.?
1.15 kJ is transferred to 3.4 lbm air Q = Cp×m×dt and dt = Q/Cp×m dt = 1.15 kJ ÷ ( 1.005 kJ/kgK × 3.4/2.2) = .74K
Q:Home heating it's cold (re-post to answer rec'd) ?
Q:need of ebook on cross flow heat exchanger, give me some links?
Here okorder.com/
Q:Plate Heat Exchanger experiment improvements?
If you're not 100% certain if something might be important/vary if you can it's best to test/measure it anyway. if a change in something doesn't affect the results then you found by experiment that (in the situation tested anyway) that it's not that important a parameter, but look up Feynman's cargo cult science lecture- it explains the often forgotten significance of null results- calteches.library.caltech.edu/51/... . ie Just because something doesn't cause a change, doesn't mean it doesn't add to knowledge. Goal of experiment should be to collect data (not fit a model- that might come afterwards), and if you've not measured something it you can't account for it in your dataset except by repeating it/relying on someone else's findings. you can always ignore data if it's same in all circumstances you want to try to keep everything you're not measuring to be the same, between different runs. try getting temps of water/wall paper not just temp difference. try making sure the heat ex, and the fluids all start out at the same temps. I'd guess changes in pressure drop could change turbulence. Only way of finding out if that's affects heat flux significantly is to test it.
Q:Sizing a Plate Heat Exchanger?
Download okorder.com/.. Its a trial version and design it with the help of it easily.
Q:Impact of steam quality in heat exchangers?
If you have steam with a few degrees of superheat you are less likely to have low quality steam in the exchanger. That is the real problem is low quality steam which doesn't have it's full latent heat and therefore requires more steam to deliver the same quantity of heat to the exchanger.
Q:Why is my Coleman propane furnace smoking?
Sounds like a busted heat exchanger. The flames dancing all over when the blower kicks on is a sure sign blower air is reaching the combustion air. Another symptom of this is CO2 and smoke entering the house. A sooty, raw smelling burn is another indication as well. Basically it is dangerous to operate as one busted that bad will let high levels of CO into the house.
Q:How do you calculate individual heat transfer coefficients in a heat exchanger?
Just okorder.com/ and it'll do the computing for you in a more convenient way it includes solution, etc
