2.New Technology Description:
Five-ColumnThree-Effect Distillation Process
Our company designs and manufactures latest Five-Column Three-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 Distillation Process
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;it saves over 40% steam

- Q:Here's the situation:We have two heating units in a single level house. One heats the den, kitchen, living room, dining room and two baths. The other unit heats the 4 bedrooms and one master bath. Return #1 is in the den beside the hallway. Return #2 is in the same hallway centered among the doors to the bedrooms. For Unit #2 the vents to the master bedroom and bath are closed. The vents in the other three bedrooms are open. Only one of these bedrooms is being used. It's my mom's who leaves her door closed all the time.My mom says we are wasting money heating the two empty bedrooms. I say we have to leave them open so the unit will get circulated air. If I close off the two empty bedrooms, the only one with an active heat vent has the doors closed which will cause the unit to run unnecessarily costing even more money.I say both units have to be running.So who's right????????
- The exterior walls of your home are insulated to keep out the cold. The interior walls are not. If you allow one segment of your house to become cold it will cause the rest of the house to be colder. Instead, insulate and weatherstrip everywhere. Put up double glazing on the windows and anything else you can do to improve the barrier against air infiltration.
- Q:I was wondering of a liquid cooled jacket that you could wear i.e. summer is hot and cold water feels good, and why not wear a liquid cooled jacket a tube circulating cold water that cools your body/limbs or in a cold winter hot water circulates around your body. Im not making sense im saying can there be a jacket that transfers cold/hot water around your body in a tube and it keeps you warm/hot, and can a such thing exist or it could be a new thing???
- there okorder
- Q:Heat exchanger performance characteristics?
- 4. Heat transfer speed, high temperature (400 ℃), high pressure (2.5Mpa).
- Q:I was told there are cracks and I have elevated levels of CO. I have no money please help so I can get this fixed.
- Carrier and a few other brands actually have a 20 year parts warranty on only the heat exchangers.there is limited part availability on some brands and the bonnet and furnace other than exchanger has to be in good working order.don't run it in heat!!!!!.......do some research ....you've got it professionally diagnosed I assume...some can be repaired but I highly do not recommend it...
- Q:It is on a timer to come on everyday,when i get up to go to work and when i have a shower and is set for an hour each time.Is this too long or not long enough? Thanks
- What is your fuel source? Gas or Electric? The best thing is to have it set to a thermostat and when the Temperature is at the setting you set it turns off. If it is set too low it will never shut off. Increase the insulation. Gas is more cost effective and it will give you more BTU's sooner. Does your Boiler work with a heat exchanger? It is more efficient to have a closed loop system of a saline solution mixed with an oil will hold the heat better than purified water. A timer is a waste.
- Q:Why mechanical engineering students need to study heat transfer?
- ALL mechanical processes result in the production of heat and therefore are affected by heat. Understanding the mechanisms of heat transfer is essential to understanding mechanical design.
- Q:I heat my home with a boiler/hot water/radiator system. It's a very old system using natural gas to fire the boiler and a circulation pump. I recently cleaned it and turned the flame much lower than where it was set. My logic was that too much heat was being wasted out the flue pipe and chimney. It still heats the house with no problem with a water temp of 120-130 degrees. Question is, will this save me money on my fuel bill?
- the installers could have used the incorrect length pipe for the exhaust. the superb element at this element could be to have a individual from Rheem (it rather is normally a close-by producer's consultant) come to your place to come to a decision why it rather is not working. If it maintains, and no person grants an outstanding answer- its real that Rheem ought to the two replace it at their cost, or refund you funds so as which you will get a clever one someplace else.
- Q:Data about heat exchanger tube are listed below.Tube materials: Cu-Ni 90-10 (UNS C70600)Service liquid: sea water (tube) and propane (shell)Sea water cools down propane down to 40 C (104 F)
- You haven't stated what kind of failure. Is it pin hole leaks from come form of corrosion or splits the tubes or even buckling. If there is a lot of debris in the water, it can plug some of the tubes causing them to overheat and split or buckle. If there is mud or silt, it can plate out on the tubes and cause hot spots that lead to failure. There could also be a problem with the actual manufacture of the tubes in terms of the alloy or even the welding of the seams if the tubes are not seamless.
- Q:I have a water tower with an open loop condensing water system to plate heat exchanger then a closed loop in the building. Why? Also, there is a second heat exchanger (appears to be shell and tube). Why?
- The cooling tower and plate combination is used to cool a chemical liquid in some process usually (in the closed loop)...Probably the same deal with the second exchanger. The shell and tube exchanger is usually used to heat or cool with water/steam in some chemical process... --to be more specific I would have to see more..or have a little better description.
- Q:Can i use plate heat exchanger to cool down fermented yogurt (from 43 degree to 10)? I just worry it might block the heat exchanger. Please help. Thank you!
- I heat my milk,and I use a bit of cream for mine, get it to blood temperature, take it off the heat, let it sit for 5 minutes then stir in 1 250ml plain Balkan style yougart (Canadian brand), pour into cups, and I have a plastic container, I place the cups in, top with a loose piece of plastic wrap, set this on top of the frig, and allow it to ferment overnight, i the morning I put the cups with there covers in the frig, the yougart culture has to work at a constant temperature to firm.
