Biodiesel-Sunshine-In-A-Jar

Well we are fast approaching 2010 and here at www.homebrewpower.co.uk we are thinking about what we can offer up to our readers and customers.

We have decided that one of the main aims of 2010 will be to produce our own Bio diesel from WVO (Waste Vegetable Oil) We believe we have sourced a supply of waste oil to use for bio diesel production and have the knowledge to create a Bio diesel reactor.

Bio diesel is pretty much ,'Sunshine in a jar' It will provide our diesel van with all the B100 fuel we require.

We are also working towards a WVO powered heating system using Babington technology for heating our conservatory and with forced hot air the garage and workshop areas of our premises. Our aim is to design a fully automated, fail safe Babington heating system that uses waste vegetable oils for fuel.

We will post updates as and when they happen (Time permitting)

Air-Bubble-Lifter-For-WVO-WMO-SVO-For-Turk-Babington-Burners

Air Bubbler Oil Lifts are a great way to regulate various fuel supplies for Waste Oil burners, some great examples are the Turk Burner and the Babington Atomizing Burner.

The schematic above shows you hot to construct one from simple materials.

The principle is as follows: Air is supplied at approximately 6 PSI from a simple low pressure air pump (A fish tank air pump is commonly used in home made devises) down a copper tube to a tee piece, the arrangement is submersed in the oil tank / reservoir to allow the bubbles to rise up the outlet tube, as the bubbles rise up the oil filled tube they push up an amount of fuel oil above them. The more air you supply the more oil is driven up with it.

The above principle can be used in so many different burner applications and situations where a controlled and constant amount of oil is required at the burner nozzle / jet. the oil once passed over the burner nozzle that remains unburned can be easily channeled back into the oil sump / tank and recycled.

Note to consider!

As oils become warmer, as they would in the above setup, they become much thinner (Less Viscous) best practise an such a system would be to monitor the fuel oil until your system is up to a stable running temperature i.e. the oil temperature ceases to rise and then set your running air pressure. A Hasty setup on such a system could cost money and indeed lives (Play safe)

Babington-Oil-Atomizing-Balls-Have-Arrived-In-The-UK

Our batch of hand made Babington Oil Atomizing Balls have arrived at HomeBrewPower!



Close-Up of a Babington Ball

Our order of custom made Babington Burner Balls have now arrived at HomeBrewPower UK.

These Nozzles enable the clean burning of Waste Vegetable Oil, Straight Vegetable Oil, Waste Motor Oil and any other combustible oil you can think of!

The principle is really simple, ' The Babington Ball is connected to an air source (Car tyre inflator or any other small air source capable of producing around 30-40 PSI via a 1/2" NPT standard fitting) A tiny stream of air is jetted out of a 0.010" presicion hole in the middle of the Babington Ball. Oil is pumped over the outer surface if the Ball producing a thin film around the ball head.

Where the jet of air is expelled the oil is Atomized into mist which can be readily burned. The atomizing effect is known as the Venturi effect similar to the principle of a whale expelling air when it surfaces.'

An air lift pump can lift a liquid to a height above the surface of the liquid equal to about 2/3 of the depth at which the air is injected into the bottom of the vertical pipe.

The capacity of the air-lift pump depends largely on the percentage of submergence of the foot piece; that is, the greater the submergence of the foot piece below the water level in the discharge pipe, the greater the volume (column) of water the pump can deliver per unit of time. However, the deeper the foot piece is submerged, the greater the compressed air pressure must be to lift the column of water.

In air-lift pump operation, compressed air has to be regulated correctly. The amount of compressed air should be the minimum needed to produce a continuous flow. Too little air results in liquid being discharged in spurts, or not at all. Too much air causes an increase in the volume of discharge but at lower discharge pressure. If air is increased still further, discharge volume begins to decrease

Some details for water pumping..

Sizing the air lift pump
The flowrate through an air lift pump is proportional to the flowrate of the air powering it. The literature reports air lift pump flow rates of 20 to 2,000 gpm and lifts to more than 700 ft.
An empirical calculation attributed to the Ingersoll Rand Co. correlates the flow of air with that of water.

Va = 0.8 Ll/(C log10{(Ls + 34)/34]
Where Va = volume of free air (cu. ft.) needed per gallon of water
Ls = length of the submerged section (ft.)
Ll = length of the lift section (ft.)
C = constant that depends on Ll (see Table 1)
Another relevant variable is the relationship between Ls and Ll. Functional air lift designs exhibit a curious non-linear phenomenon. The ratio of submerged length to total length, Ls/(Ll + Ls), runs about 0.6 when the lift is only around 20 ft., but decreases to about 0.4 when the lift is 500 ft.

The last relevant variable is the air pressure needed to make the device operate. This depends, of course, on the specific gravity of the fluid. The depth that corresponds to one psi is inversely proportional to the specific gravity. For water, one psi corresponds to 2.31 ft. of depth. If one ignores the friction losses in the line, the applicable relationship is:

P = (Ls * sg/2.31)
Where
P = required gas pressure (psig)
sg = specific gravity of the fluid (dimensionless)
