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 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;itsaves over 40% steam

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:where can i find steam packages which used for heating in heat exchangers?
Are you asking about a source of steam like a boiler? Those are available in various sizes and types depending on process requirements.
Q:How do they heat a hot yoga room? Is it with dry heat, steam?
It depends. The studio that I go to uses heat pads and a humidifier. The heat pads go on the roof and heat comes off them. If the heat is too high, they just open the windows or use ventilators. That's just the studio that i've been to though.
Q:can oil heating cause carbon monoxide poisoning?
What matters is whether or not the fumes from the burned oil can get into your house. The chimney should be high enough to stick up over the roof of the house, which ensures that fumes cannot blow into the house. If your house is heated by steam and the chimney is high enough, its not very likely that fumes would reach your house. If your house is heated by forced air, then cracks or holes in the heat exchanger could carry CO into your house.
Q:An air-to-air heat pump has many of the same components as an air conditioning system. The majordifference is?
Actually, they are the same, and often the same unit does both functions, (winter heating and summer cooling). The only difference is that it works in reverse, that is in winter mode it absorbs heat from the outside air and radiates it inside, and by switching which of the two heat exchangers is getting the pressure, (summer mode), it absorbs heat from the inside and radiates it outdoors. This change-over is done using electrically operated valves that effectively reverse the direction of the compressor to reverse the action.
Q:Is there a way to take a little heat from a lot of water and make a little water with a lot of heat?
You would need a heat exchanger, like what you would find in an air conditioner. A heat exchanger uses the phase changing properties of a refrigerant to move heat from cold place to a hot place. Essentially, it expands the refrigerant into a gas that is colder than your large water volume, so that the large water volume can dump heat into it. Then the refrigerant is compressed into a hot liquid so it can transfer the heat to your smaller water volume. The range of temperatures you can achieve is limited by operational temperature of your refrigerant, and the heat exchanger does require energy, so its probably not very feasible.
Q:What is the most cost effective way to heat my boiler?
What is your fuel source? Gas or Electric? The best thing is to have it set to a thermostat and when the Temperature is at the setting you set it turns off. If it is set too low it will never shut off. Increase the insulation. Gas is more cost effective and it will give you more BTU's sooner. Does your Boiler work with a heat exchanger? It is more efficient to have a closed loop system of a saline solution mixed with an oil will hold the heat better than purified water. A timer is a waste.
Q:Thermal efficency in a heat exchanger?
Thermal efficiency = Useful output/total input X 100% Thermal energy required to boil and evaporate 1kg of water = (Rise in temperature)(Specific heat capacity of water) + (Specific latent heat of vapourisation) = (100-70)(4187) + (2257000) = 2550090J Therefore, Since 1.5Kg of water is turned to dry stream per second, Useful Output = (1.5)(2550090) = 3825135J Total Input = 4000000 Hence, Thermal efficiency of boiler = 3825135/4000000 X 100%= 95.628375%= 95.6% (3 significant figures) Hope this helps.
Q:I have had my heat ex changer replaced. My furnace does not heat like it did before. any sugestions?
It is quite possible the one that was installed is not as powerful as the old one you had? Kinda like putting a small motor in a big truck?
Q:How to calculate shell thickness for shell and tube HX?
Since you are designing STHX, The Shell of heat exchanger does not form the main heat transfer surface area. It only loose some heat in to the atmosphere. Hence heat transfer calculations are ruled out. The major consideration is Corrosion rate and life time. For the normal shell materials with normal flow velocity The maximum corrosion rate is 5mm/year. At the end of life time also system integrity should not fail means it should have structural strength too. So the minimum wall Thickness is Corrosion Rate X Life in Years X Factor of Safety = Thickness in mm.
