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

6.Package & Transport
- Q:This is a residential 80,000 BTU 95% efficient High Boy Carrier forced air furnace with a condensing heat exchanger.
- too high to estimate
- Q:I was wondering if I could put a heat exchanger behind a refrigerator to heat water. I heard that they give off a lot of heat will this be enough and is this feasible. Also would this be efficient?
- Great idea. I have never seen it designed, but I believe it would work. The heat is not enough to heat hot water to final temperature, but could be a preheater and save kilowatts.
- Q:Ideas for experiments I could do in school that are related to keeping things hot or keeping things cool?
- Can you boil water in a baloon before it bursts? (Use a lighter to heat a mostly empty water balloon)
- Q:replaced attwod pump antifreeze is flowing good . sea water seems to be flowingthrough plexie glass engine runs cool at low rpm when crusing quickley heats up. any help with this would be great thanks for reading
- Sounds like you have something sticking or wearing out in your cooling system. The best answer would be to take your question and/or boat to a marina or boat mechanic.
- Q:After my heating system is shut off, (let's say after 10 PM), my fan is still running for a while (about 15 - 20 minutes). Meanwhile, it makes some noise. 1. Why is my fan is still running for quite a while after the heating system is shut off? 2. Why it makes noise? 3. How to fix it?
- This is a poke. Gas furnaces have fan limiters which determine how long fans run during the heat cycle. They're adjustable I know, but I can't help you much in telling you where the limiter is. Why is the fan making noise? It might just need some ordinary cleaning and light oiling.
- Q:How does the rate of heat transfer differ between a solid (through conduction) and a liquid (through convection)?
- It's somewhat difficult to answer this question simply. First it is important to know that convection is really just a version of conduction. Heat has to transfer through molecules, or groups of atoms, and thats exactly what is happening in both forms of heat transfer. You're professor might not teach you this outright but it is in fact the truth (ask him after class and he'll tell you the same). But to answer your question, you have to look at the atomic structure of liquids and solids. The atomic structure of solids are more dense than liquids so the atoms are more in contact with each other, therefore heat can transfer faster than liquids in that aspect. However, if liquids are motion they transfer heat at a faster rate. By using some sort of force to move the liquid, the atoms can move the heat at a faster rate. Think of a heat exchanger; they pass a fluid (a liquid or gas) through the interior of the system to transfer the heat faster. To do so they speed up the fluid at a fast rate, while also creating a phenomena called turbulence in the fluid, to have the most efficient heat transfer. So overall, if a liquid and solid are motionless then a solid has a faster heat transfer rate. If there is motion in fluid then it has a faster heat transfer rate. Hope this helps!
- Q:Sometimes I close off 3 heat vents in my home.There are cold air returns in all rooms except a very small bathroom
- The key words in you question are too many. How many other rooms do you have? more than 3? then you are probably OK. But be smart too. The cold air returns (unless you cover them up) will continue to draw cold air from the returns but not as great of a rate because of reduced pressure and then draw air from under the door if needed (unless you seal that too - please don't). This will increase the pressure in the rest of your system/house. For the most part this is not a big deal unless the three rooms represent a majority of your home. Heating systems are designed on cubic feet. if you reduce the amount of cubic feet then you reduce the amount of heat required. I believe you are trying to save fuel cost. Just make sure the rooms don't get too cold. Sometime just closing the vent MOST but not all of the way is the wiser decision. Stay warm!
- Q:Say a curved 2m Square mirror board is reflected and focused to a 0.01 Square meter area, does the temperature (t) = 200t?
- The energy density of the sunlight hitting is 200X higher but that does NOT mean the temperature is 200X higher. There is a solar power electrical generator that uses a lot of mirrors to focus sunlight on a heat exchanger that is cooled with water (a solar powered water heater), the water heats up, boils, and the steam turns a turbine.
- Q:Comments on Trane XV95 furnaces Please. Is st stl heat exchanger the best way to go?
- Absolutely... st more, but will last forever
- Q:turn the heat back on and then heat works fine for a couple days then cuts off again. I have to keep repeating the process. I have replaced thrmostat, circuit board and gas valve. Anu suggestions? Furnace is 9 yeras olds made by Solitare.
- sounds like a faulty thermostat, they can be replaced and only last two minutes
