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:how do we select the best heat exchanger in terms of cost,material and weight?
- depends on what youre budget and the intended application are.
- Q:Hi.. I'm kinda confused with this one... i hope someone helps me here !A dryer operates for 60 hours/week, 50 weeks/year. It exhausts 200 kW/hr of heat and the value of energy is 6p/kWh. A heat exchanger with a 50% efficiency is put into the exhaust stream to recover a proportion of this heat. The installed cost of the heat exchanger is ?22,500. The heat exchanger pressure drop needs a 2 kW fan to overcome it, and the cost of electricity is 10p/kWh. (I have the final answer - but no luck getting it !! - 10 points to the one who gets it right with good enough explanation for me to understand :)Thanks !
- You don't actually ask a question! But I can guess where the problem is going. Always carry the units along to help keep things straight. BTW, dryer is 200kW hr / hr or 200kW. Dryer operates = 50 wk/yr * 60 hr/wk = 3000 hr/yr Dryer cost = 3000 hr/yr * 200 kW * ?0.06/kWhr = ?36,000/yr Cost to operate heat exchanger: = 3000 hr/yr * 2 kW * ?0.10 /kWhr = ?600/yr The heat exchanger recovers: ?36,000/yr * 50% efficiency - ?600/yr = ?17,400/yr Now, if the question is payback period, it is: = ?22,500 / ?17,400/yr = 1.293 yr
- Q:heat transfer - engineering
- Automoble radiators . Air cooled air plane engines . Baseboard heaters . Air preheaters . Some boiler superheaters on the flue gas side
- Q:how to make use of the heat evovled from diesel engine?
- Heat exchanger, turbo or an adiabatic engine.
- Q:It has been really cold for the last few days and heat is working but is not reaching desired temperature. It shuts off and then starts again. Reaches about 6 degrees below desired temperature and once shut off, the temperature drops significantly and then it starts working again. The furnace seems to work fine when it is on but need to understand why it doesn't reach desired temperature.
- The temperature set on the thermostat may not be in line with the temperature displayed on monitor.It happens on reaching upon the set temperature,when it trips,it goes to a lesser temperature.The working of the thermostat seems to be faulty.
- Q:a while back, I found a 150,000 btu hanging furnace on the roadside that someone had put out for the trash pick up. I looked it over and everything seemed in order. I took it home, cleaned it up, cleaned out the gas inlet filter, hooket it up and it worked fine. I originally picked it up thinking I could use it in the garage but I don't work out there as much as I used to. So now I'm wondering how I can turn it into a heater for the pool. Pool heaters are sooooo expensive. I've already cannibalized a hot tub heater for the electrical heating element but it only heats the water approx. 20 degrees above the pool temp and I don't have very much flow from it. So what kind of ideas do you have for turning this furnace into a pool heater?
- Bastardize together the heat exchanger from a pool heater to the furnace. However, I HIGHLY do not recommend doing this. You have to have a flow limiter on it so that when the flow stops the gas stops or you will burn out your exchanger and furnace. The sizes are different so you are going to have to build a metal containment box or enlarge the containment unit currently there. Again, I HIGHLY recommend against doing this. There, I think I've satisfied the warnings ;-)
- Q:I have only seen absorption heat pumps that use entropy to pump heat, but is there such heat pump that uses just continuously replenished thermal energy alone to pump heat from one location to another. This would have the enormous advantages of being able to generating power without a cold sink, allowing heat engines to operate outside of our atmosphere, say on a lunar base. It also add stealth to nuclear submarines because they would not leave a quot;thermal wakequot;.
- It wouldn't be a heat pump if it only had one heat exchange region, it wouldn't be a heat pump anymore...it would be nothing more than an electric resistance heater or an exothermic chemical reaction (or a thermodynamically equivalent design). If by heat pump, you mean refrigeration cycle or air conditioning, where heat is trash instead of treasure, you MUST have a region for heat rejection, otherwise it would violate the second law of thermodynamics. To add stealth to a vehicle, you could accomplish this by storing the trash heat in an insulated vessel of water, and then replace said water when in a region where stealth is unimportant. If you want a refrigeration cycle to operate in an airless environment (on the moon or in interplanetary space), the ONLY method of accomplishing heat rejection is via a heat exchanger which operates with radiation on its outside, radiating waste heat to the background via naturally produced infrared of black body radiation.
- Q:thanks for the help
- Go here www.google.ca/search?hl=enq=How+... And do some search Hope this properly answers your question
- Q:the water would take way longer to cool down then the components would generate heat, for air you get new air can't get new water in a closed system
- it incredibly is a hotly debated subject count. i'm prepared on followers myself. much less generic worry. seems such as you does not possibly appreciate making use of a liquid cooled workstation through fact of each and all the justifications you have given. except you have overclocked, liquid cooling isn't mandatory. So get high quality followers which at the instant are not making a number of of noise, and situate the workstation so the front of it gets some air from the AC unit you have interior the summertime. verify to flow it interior the winter, far flung from the grille of the ducts in case you have a warmth pump or effectual ac/warmth. shop the interior vacuumed out suitable, or very intently use canned air to dirt it, and you'd be golden.
- Q:List the three types of Heat exchangers?1,2,3,
- Parallel cross counter flow
