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 sort of routine maintenance should i be doing for my central heating and air system ?
A good visual inspection of the coils,wiring, and heat exchanger is a good start and light cleaning as needed. Also secure any copper refrigerant lines that may vibrate or rub on anything that would cause a potential refrigerant leak. Also make sure your thermostat is level.
Q:Heat Exchanger Problem - effectiveness & outlet temperature?
I keep a programme developed by engineering students under my supervision, years ago. Feeding the information provided by you, I present the the whole result after running the programme. Your calculations are OK. Number of Transfer Unit (NTU) = 0.1194429 Heat Exchange Rate (Q) = 2230.982 W Hot Fluid Temperature At Inlet T(h,i) = 90 Centigrade Cold Fluid Temperature At Inlet T(c,i) = 22 Centigrade Hot Fluid Temperature At Outlet T(h,o) = 82.63702 Centigrade Cold Fluid Temperature At Outlet T(c,o) = 27.33728 Centigrade Cold Fluid Mass Flow Rate = 0.1 kg/s Hot Fluid Mass Flow Rate = 0.3 kg/s Overall Coefficient of Heat Transfer (U) = 80 W/Sq.m.K Area of Heat Transfer (A) = 0.45239 Sq.m.
Q:Do i need a new furnace?
Furnaces will last 25-30 years on average, although newer ones will save some energy. The statement about the pilot system is a tip off that you got a con man who is trying to sell you a new furnace. Get another opinion, and don't mention the first one at all. When they give you their opinion, then you can ask about the heat exchanger, if they didn't mention it.
Q:How to fix heat exchanger hole?
if few or couple of shell pipes have leaked u can block those pipe but if more u need to change .. inspect it properly and try .
Q:geo thermal a/c heat exchanger usefull or wase of money 4 Fla?
Miami or the panhandle? Actually makes a difference. You need to know your cost of a KWH from your electric supplier. A competent dealer/installer will have software from the a/c manufacturer that will estimate the annual KWH for a geo and air source a/c of the same tons rating. That will give the savings in kwh for the geo thermal unit. Multiply that by the cost of a KWH and you have the annual savings for the geo unit. Divide the cost difference for the geo unit by the annual savings. If that equals a number less than 8, then the geo is useful.
Q:Is a swimming pool heat pump suitable in the uk for all year round swiiming?
For an air to water heat pump, no, not really as a stand alone unit. Yes, if you add a gas fired heater as a back up for days that the outside air gets below 0C and you're sensible in keeping a solar blanket on the pool to minimize heat loss. As a general rule, when the air temp gets to -10 C, these units won't give you any heat at all or at least not enough to offset your pool's heat loss. If it's a geo thermal heat pump, your ability to scam heat gets better because you have a warmer source, but your costs also go up as their pretty expensive to buy and install. I've only ever seen this type in conjunction with household heating that has had the extra heat exchanger installed for the pool heat.
Q:what is a heat pump, how does it work?
It works on the basis of second law of termodynamics , which states heat can be transferred from a source at lower temperature to a sink of higher temperature , if work is done on the system. It is just like a refrigeration system. A refrigeration system works like this: Source-----Q1------> Work by compressor ---------Q2---->Sink The heat Q1 is removed from the system making a space cooler and discharging the heat to the atmosphere when work is applied through a compression system However if you see a heat pump, it is on the same principle, the only difference is that the sink becomes the heated area and the source becomes the atmosphere , that is why it is called a heat pump, the source is atmosphere and the sink is conditioned heated room area in this case!
Q:Help with Designing a Heat Exchanger?
First you need to determine how much heat must be transferred to cool the oil. (Q) Assuming you are going to have a counter flow exchanger you have assume an approach temperature for the cooing water. With that you can calculate the log mean temperature difference. (LMTD) You next need an over all heat transfer coefficient. There are several online sites where you can get typical coefficients. (U) With this information you can calculate the area of the pipe needed and from that the length you need. (A) The equation is : Q equals U X LMTD X A. Solve for A by dividing Q by U X LMTD NOTE : go over size because you can always cut back on the water.
Q:Impact of steam quality in heat exchangers?
besides to value, steam jackets are utilized in lots of cases the place you do no longer desire to administration the temperature precisely yet basically desire issues warm. yet another application for jackets is the area the place the cloth being heated can plug an excellent-unfold warmth exchanger's tubes.
Q:liquid side pressure drop for finned tube heat exchanger?
The calculation is done the same as it is for a shell and tube exchanger. You are basically determining the pressure drop through a length of pipe. If you assume the flow is spread evenly in the various tubes of a heat exchanger then you can do the calculation for one tube with its entrance and exit losses and have a pretty good estimate of the over all pressure drop. Just remember these calculations are only estimates and you will see a different pressure drop in the actual exchanger.
