One problem with the conventional E-spirit is that it contains fairly large proportion naphtha. It makes that the spirit burner sooner or later have to be
cleaned from unburned fuel deposits. These coatings are a minor problem when one dispenses red glycol in the E-sprite. In order to completely circumvent the
disadvantages that may arise, one must dispense a certain amount of methylated spirits in the e-sprite. Then one avoids the risk of turbidity / phase separation
and naphtha coatings. What you pay is the price of the extra methylated spirits, which must be purchased. Despite a higher cost is the price still cheaper than
to run with pure methylated spirits. One can make a big batch as methylated spirits are cheaper in cans. If one choose to do E-spirit+ is the proportion of E85
lower. Those mean that the gasoline (the reminder) will be reduced and therefore contains the gasoline less naphtha. If one chooses to use two five litre cans can one proceed as follows: Do the actual preparation of E85 fuel, water and naphtha in one can - the second can is filled with E-sprite. Then add some methylated spirits or some other cheap alcohol... The batch is matched so that the amount of methylated spirits/alcohol becomes right when the can is completely full. You start by filling the can to the three litre-line with E85. Then add 5 vol% naphtha and 25 vol% tap water. This is 150 ml naphtha and 750 ml of water. Together is it 3900 ml but due to the shrinkage will it be about 3.7 litres. Then wait a few hours before separation begins - via a PVC tube by utilizing siphon principle. Time is not directly critical here, 3 to 5 hours is about right. The amount of E-spirits in the other can, will be after separation about 3.3 litres. Then fill up with methylated spirits/alcohol up to the five litre mark. One now have five litres of E-spirit+. This liquor can now be used as fuel for indoor heaters. An alcohol analyzer (hydrometer) shows 87%. Dose with pleasure a half thousandth (0.05%) of red glycol in the amount of E-spirit+ (one millilitre per two thousand millilitres of e-sprit+).

A content list (by volume):
Characteristics E-spirit+ has a density of 830 kg/cbm and the calorific value is about 24 MJ/kg. It is a substitute for methylated spirit and contains naphtha, which makes it feel fat/slippery in comparison with methylated spirits, thereto contain it water. It burns relatively safe and does not turn off by itself. Incinerates E-spirit+ in dedicated liquor burner formed no water but if one incinerate it in a bowl will the combustion become incomplete, with both water and soot as residues. The flame is yellow and sooty but cause no more trouble with the indoor environment than with tea lights. For methylated spirit is the calorific value 28.5 MJ/kg and is slightly better than E-spirit+. For a certain amount of methylated spirit requires 15% larger amount of E-spirit+ for not the calorific value should diff. At a price comparison may one take 1.15 times methylated spirits (which gives the amount of E-spirit+) and to get the amount of E85, one takes the amount of E-spirit+ and multiplies with 0.6. The amount of naphtha is 0.05 times the amount of E85. In 2011 were E-spirit+ about 30% cheaper than methylated spirit in cans. If one recycles the gasoline reminder as an engine fuel is the profit rather 35%. As with regular E-spirit (which emits smoke when a burner peters out) will also E-spirit+ produce smoke. The smoke is derived from unburned naphtha and as the E-spirit+ contains less naphtha will it also smoke less than ordinary E-spirit. The resulting smoke is comparable to a candle or a tea light in intensity. The burner after-heat seems to be enough to vaporize all naphtha. My two smoke alarms that are placed at the ceiling and in the same room as my spirit burner, has not started to alert yet. E-sprite+ is not a good cleaning then the naphtha creates stains and because it contains water, it may stir up rust but then it contains naphtha, it may be vice versa? The amount of E-spirit+ can approximately be calculated from the available volume of E85: Amount of E-spirit+ = 1.7 x E85 The amount of the residue is approximately 0.15 x amount of E85.
