2.New Technology Description:

Five-ColumnThree-Effect Distillation Process

Re-boiler

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

Re-boiler

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: What’s the quality of Ascent Heat Exchanger Brass Tube? Have you ever cooperate with “Ascent ”? Any advice?: Applied vacuum melting technology, our tubes are of superior quality: stable chemical composition, precise dimensions, and clean, smooth and bright inner and outer surface. Good mechanical properties - free from defects such as blowholes, cracks, pin hole leaks etc.

Q: I've just been wondering, I have this physics project and we have a budget of ?50,000, at the moment I'm well under budget which is good but I was just wondering, if i locate a house near a hot spring, could i use the hot spring for heating the house, i can use it for hot water but I'm not sure about heating, if i can, how? Thanks :): There are many places where the water from hot springs is distributed to the houses for heating and bathing purposes.

Q: Price of heat exchanger for a furnace?: If the heat exchanger is under warranty I suggest you buy a new heat exchanger. Some of these have a warranty of 2 years to a lifetime warranty. if it is not under warranty, I suggest you gather some quotes for a new furnace even though it will still cost you more to replace the whole furnace. The supply house COST of one can vary. $0 (warranty) - $3,000. (usually around $500 for residential)

Q: My heat exchanger on a 10 year old Janitrol went bad. Sure the company warranty exchanged the part, but it still cost me over $400 in labor... YIKES ! ! ! Learn from my MISTAKE, NEVER... and I mean NEVER buy a Janitrol: They had their share of problems over the years this is true, The new stuff they are making is a leap ahead of the old crap. Janitrol furnaces have been around for over a hundred years, but Goodman has not. They are the cheapy of the cheap furnaces. You get what you pay for. Janitrol went out of business and Goodman bought the name.

Q: I have a fresh water cooled 8.1 liter gas engine in my Carver yacht. I serviced the seawater impeller and seawater pump. Water drained out when I did this. At first I thought it was just seawater, but do you normally top of the fresh water system when doing this job? I added a gallon of distilled water in the freshwater heat exchanger, but the engine seems to still get hot and makes warning beeping sounds. Should I fill the heat exchanger to the top with freshwater? Is there something else I should be doing?: First your boiler is a GAIA 424/8 S or RS do not recognize the form off hand yet maximum combes are very a lot alike. do not recognize were you obtain Knightsbridge from. Your difficulty appears like a diverter valve diaphragm at fault. With the critical heating became off, look on the valve unit (large brass block 3 large pipes and a couple of small ) on one end is often fixed a change block (black in shade) that is actuated by technique of a pin that is pushed out from the valve even as the nice and cozy water tap is became on, is this operating if not then its the diaphragm. utilising a small screwdriver gently perform the micro change does the boiler stir up now. If sure then the electronics are ok.

Q: what are benifits/advantages and disadvantages of Hot water heating, Steam heating, Forced air heating and electric Baseboard heating?: I perfer heat pump ,auqatherm, or gas heating

Q: I plan to design the microchannel heat exchanger for seawater desalination plant, by using naval brass and titanium as its materials.: take your specs to alfa laval and ask them. product flow rate, product input pressure, and max pressure loss, service flow rate, service input pressure, and acceptable pressure loss, product input temp, required product outlet temp, and service input temperaure These are the minimum specs required. . general matl. is stst.316, but alfa laval can price in many matl.s . with the above specs they use a pc program to quote, so its no big deal to quote several different arrgts. . find your local agent, and with your specs, talk with them. cheers

Q: I want to know about heat capacity!!!: The amount of heat required to raise the material's temperate by a degree. Temperature is just a measure of the speed of molecular movement inside a sample. At the theoretical limit of absolute zero all movement would be stopped, but that point can't be reached. There are several different ways to use the term heat capacity; but each term is a measure of how much energy it takes to increase the temperature.

Q: We have a Payne Plus 90 gas furnace. It just doesn't keep the house warm anymore. A couple of winters ago, we had this problem and the service man told us that it isn't designed to operate below 25 degress. It sits in the garage. That sounds crazy. This winter, it isn't working well either.So what happens is that it turns on, and only runs for maybe 6-8 minutes before shutting off. It might be hours before it comes back on again. We are calling someone to come out next week, but I am just wondering what we could possibly check for this weekend to get it going.We checked the water drain trap, and cleared it. It did not have a clog or build up of water.We replaced the thermostat in the house because we first thought it just wasn't sensing the right temperature. The replacement one has a digital thermometer, and it is right, it is like 65 degrees in here! brrrthanks: Your repair man is right, the furnace will not operate in those cold conditions. Your furnace is a condensing furnace and that means it has water inside of the secondary heat exchanger, all the tubes, hoses and the trap. Simply put you have water freezing with in your furnace. You have a few options 1) move your furnace to a conditioned space. 2) condition your garage. 3) isolate your furnace within the garage (build walls) and add a register to your plenum to keep that room conditioned. You will see a big difference.

Q: why is it usual to feed water from the bottom in heat exchanger?: Because heat rises. This is called natural circulation. The second reason is if air is in the system you want it to flow to the top instead of letting it cavitate in the water that would be flowing against it if it were fed from the top. ???
