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

6.Package & Transport
- Q: When do we need correction factor for a heat exchanger?
- Typically these are used for cross flow exchangers or other odd exchanger configurations.
- Q: and plz list your name/email so i can list you as a resource 4 my sci. paper
- Convection involves the transfer of heat by the motion and mixing of macroscopic portions of a fluid (that is, the flow of a fluid past a solid boundary). The term natural convection is used if this motion and mixing is caused by density variations resulting from temperature differences within the fluid. The term forced convection is used if this motion and mixing is caused by an outside force,such as a pump. The transfer of heat from a hot water radiator to a room is an exampe of heat transfer by natural convection. The tansfer of heat from the surface of a heat exchanger to the bulk of a fluid being pumped through the heat exchanger is an example of forced convection.
- 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.
- If you can watch the fire when the Blower kicks on and the fire leaps or distorts it could cracked heat exchangers they could periodically blow out the fire by blowing it away from the flame sensor causing the furnace to shut down, also I know the Goodman manufacture had problems with controller boards even new ones
- Q: in Heat exchanger what cause the flu gases to separte from the regular combustion air that goes out to the rooms for circulation?
- The combustion gases and the air that comes out of your vents never come into contact with each other. air is drawn by a fan, thru your return vents and forced thru a chamber that has two parts, one for the inside air and one for the heated gasses from the burner of your furnace, heat is exchanged from the combustion gasses to the inside air, the inside air is forced thru vents to heat the house and combustion gasses go out the furnace vent
- Q: If I have, say a gallon or two of warm water, is there a way to transfer that heat into an ounce of boiling water? (With heat syncs or something?)
- If there's no complex set ups and containers for the water, you cannot add heat to a boiling water anymore. The boiling water is already in its specific heat level. You can no longer add more heat because it will evaporate. But for the sake of mind game, it could be done using a very complicated set up that will seem to break the law of thermo-dynamics. Search the net about SOLAR BROILER (?) Maybe it can give you an idea.
- Q: In winter my hot water is significantly diminished when I turn on the heat. When the AC/Heat is completely off, the hot water gets very hot. When I turn the AC on, the water is hot but now the AC is not cooling sufficiently. When I turn the hot water temp down on the water heater, the AC gets cooler. The AC/Heat unit is old but I've been told it's clean and running well by technicians. The problems started when I got a new water heater last year. What's up?!
- Sidecar is sturdy in this.with out understanding the motor vehicle info,it truly is tough to declare,yet those are the elementary issues...... undesirable or incorrect thermostat undesirable Coolant temp sensor undesirable Engine temp sensor
- Q: Who can explain to me the right definition of heat exchangers?
- The second law of thermodynamics says that heat flows naturally from an object at a higher temperature to an object at a lower temperature.
- Q: Like for a project, you had to make a heated toliet seat how would you do that?
- I find the padded seats seem to stay a bit closer to room temperature. I never get the cold shock from the padded seat that I get from the regular seat in the guest bathroom.
- Q: Hi guys! A furnace tech came over to my house today to do routine maintenance on the gas furnace. At the end, he told me that the quot;heat exchangerquot; in the furnace was plugged and needed to be cleaned, and that it would cost $250 to do so ($400 if he had to come back another time). This sounded kind of shady and so I declined. My question, can the quot;heat exchangerquot; in a gas furnace actually become clogged?Thanks!
- Heat exchangers do corrode, but that's generally on the outside, the part the flames contact. I have never heard of them clogging.
- Q: what is geo thermal heating for a house?
- one in all my pals had geothermal put in on his new homestead a pair years in the past. It heated in wintry climate and cooled in summer season. It on no account somewhat did the activity. He ended up including electric warmth and air. I did the electrical powered installation on his homestead. Thank goodness i did no longer scrimp on the panelboard and electric service length.
