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:Is my Furnace problem due to heat exchanger or something else? Question?
The heat exchanger is not the problem. If it works with the pipe disconnected, the pipe is clogged. Drop a golf ball into the disconnected pipe and it should roll through to the basement. If it is clogged, you could do a few things such as: use a plumbers snake to clean out the clog, or you could cut the PVC pipes, take them outside and flush them out. You can then glue them back together using couplings. You might want to check the web for your particular furnace to see if the pipe is large enough and if it has the proper end points. Some furnaces can use pipes that go straight out while others require the pipes to have specific curves.
Q:Need ideas on what could be causing smell from duct work?
Even though you got the ducts cleaned it could be the dust etc burning off since your prior furnace wasn't as powerful or efficient by the time you got it replaced. It might be funk on the a/c coil side too- make sure that was cleaned and the drain works. nyb
Q:What else can be heated by an outdoor wood stove?
right, kettle, tub and so on.... Your entire house by connecting with almost any existing heating system such as: forced air (water to air heat exchanger), in-floor radiant heat (plate exchanger with existing boiler), water heater (side arm/shell and tube water exchanger), etc. You can heat a pool, a greenhouse, a garage, a workshop and you can heat multiple buildings at the same time. Here, i'd like to recommend you www.astove.co.uk/, specializing in selling various stoves.
Q:What is the system that allows heat transfer but prevents matter transfer?
Conduction and radiation allow heat transfer without matter transfer, however convection requires matter transfer as well.
Q:What does water heat and cool?
heat always goes from the hottest place to the coldest place. when the temperature of the object in the water is hotter than the temperature of the water, it cools the object. when the temperature of the object in the water is cooler than the temperature of the water, it heats the object. this principle is the basis of an heat exchanger. in the chemistry of life i think it has to do with sweating. your body is hot, when you sweat (water), the heat is transferred to the water and the water gets enough energy to evaporate.
Q:How is a cooling tower related to a heat exchanger?
Both are heat exchangers In most cooling towers the fluid to be cooled (water) comes into direct physical contact with the coolant (air) In most heat exchangers the fluid to be cooled and the coolant, flow in separate circuits and heat is exchanged through a metal separation (very often tubes) Jim, you may consider it appropriate to acknowledge the help your respondents try to provide, If so, then please award one of us Best Answer - it costs you nothing and it's our preferred recognition. Thanks
Q:What does a repair man do when he checks your home heating unit and gets it ready for winter?
He cleans it if necessary, cleans or replaces the filter, lubricates moving parts as needed, replaces worn parts, checks the operation and adjustment of the fan, makes sure that the limiting switches turn the burner on and off correctly so that the unit starts and stops at the correct settings, checks for cracks in the heat exchanger to be sure that carbon monoxide isn't escaping into the house, and tunes the unit so that it operates as efficiently as possible, so that you get as much heat from it for the minimum amount of fuel used. When I had my furnace serviced a month or two ago, it cost me about $140, give or take a few dollars. It's a good idea to have it done every year, if possible. The peace of mind knowing that it will operate safely is worth it. Also, with the high cost of heating fuel, it's good to know that it will be operating efficiently.

Q:What temp my house heat for best money savings?
The best temperature is not one single temperature. When you are home you might want it cooler (say 67 or 68 degrees) than when other people are also there and you don't want to force them to wear multiple layers of clothing. When you are sleeping you should set it lower (say 64 or 65 degrees) than when you are awake because you won't notice the cool temperature when you are asleep; as well, you can sleep under several layers of blankets to keep you warm. When you are away you can set the temperature even lower (say 61 ot 62) than when you are asleep because you won't notice or be uncomfortable. Don't forget to also close the doors in those unused rooms where you have closed the vents as well as install some inexpensive door sweeps to keep the cool air inside those rooms and not in the areas you use.
Q:Pump work positive or negative?
They are both negative in that they are adding energy to the fluid. The pump increases the pressure, that takes energy. In the heat exchanger you are also adding heat to the water so it also is negative. The temperature rise across both the pump and the heat exchanger will be positive.
