F.A.Q

1. What savings can be achieved by using your E.F.O?

A.
We consider the total savings achieved by switching over to our E.F.O. across the board. This includes a fuel savings upto 5% in case of Boilers and Thermic Heaters, and about 2-3% in Furnaces, the reduction in electricity expenditure in heating the oil as the E.F.O requires a preheating only up-to 80 degrees, the reduction of downtime and maintenance time and the complete utilization of fuel without any wastage such as in Tank sludge. Thus, you can safely assume that switching over to E.F.O may save you company up to 10% vis a vis normal Furnace Oil. However in case you are currently using Diesel, your savings would be close to 60% with current prices .

2. What would be the Steam / Fuel ratio in our Boiler if we start using your E.F.O.?

A. Various factors effect Boiler efficiency and performance whereby it would be dishonest on our part to provide "so-called" exact Steam/Fuel Ratio figures of our Emulsified Fuel Oil. Some of these factors are:
1. Difference in feed water temperature in Winter and Summer or due to cooling tower efficiency.
2. Frequency of Stop-start operations.
3. Duration of Part-load operations.
4. Excess air percentage setting.
5. Thermal insulation due to soot and carbon deposits in smoke tubes.
6. Thermal insulation due to mineral scaling on water side of tubes.
7. Radiation losses.
8. Current Boiler direct and Indirect efficiency.
9. Economizer efficiency.
10. Combustion Air Pre-heat temperature.
However, due to a combination of improved combustion efficiency, reduction of excess air and the resultant beter thermal effeciency, the Steam / Fuel ration usually improves by at least 0.5% over that of previously used normal Furnace Oil.

3. What is the GCV and NCV of your E.F.O.?
A. One of the biggest challenges with regards to testing Fuel Emulsions is determining their Gross calorific Value as it cannot be done in a Bomb Calorimeter, due to two inherent reasons:
1. The calorimeter first flashes away the water and then takes only the reading of the remaining hydrocarbon; meaning in an emulsion having 10% water, the reading would show only the calorific value of the 90% of the remaining hydrocarbons.
2. The combustion inside the calorimeter cannot provide secondary atomization, which is the USP of fuel emulsions due to which the real energy release takes place.
The NCV(Net Calorific Value) can be determined only during combustion which is again highly subjective both to the end application as well as to associated conditions (read No.2).
Lastly, please don't be deluded by a false sense of belief that the current Furnace Oil that you use is exactly 10,000 Kcals., because our own laboratory tests have yield a range that stretches from 9000-10,500 Kcals varying from tanker to tanker and that too it is material which is strictly checked for adulteration. In fact even the oil refineries always use the term " * estimated " when writing about the calorific value of their product.

4. Why shouldn't we just install a Fuel emulsifying machine ourselves?

A.
As our team comprised of members having over a decade of experience in this field, we can legitimately say that 80% of all Fuel-Emulsifiers installed at the client's end are either under-performing, giving negative results or just kept shut, if not returned back. There are many reasons for this, starting from the poor design of the machine, to the lack of knowledge about combustion on the part of the vendors who fail to assuage the client's requirements. However, equal reasons why Fuel-Emulsifiers have been termed as failures had been the reluctance of the client's own staff in utilizing them properly, as well as the poor quality of Fuel arriving at their premises in the first place.
So, when the Furnace Oil already comes adulterated with 10% or more water and it is further emulsified with additional 10-15% water, the end results are pretty obvious. In short, unless there is a trained and dedicated team running the
Fuel-Emulsifier along with a dedicated fuel testing lab on site which would judiciously check the input, chances are the technology would never deliver upon its promises.

5. What assurance is there your Fuel also won't be adulterated on the way?

A.
We are tied to a channel partner who is also a fuel transporter having his own fleet of trucks. Each trip is closely monitored with surprise checks and with our own staff occasionally reaching the client's end while decanting the fuel to test samples. Secondly, due to the inherent nature of E.F.O is is very difficult to adulterate it by the conventionally as the same would become apparent right away.

6. If your technology is so good, why isn't it popular?

A.
It may sound poetic, but the field of Fuel Emulsification in India has seen more than its share of False Prophets; vendors of both equipment and additives who make outlandish fuel economy claims but do little to substantiate them. Furthermore, the mental block and resistance of the Furnace and Boiler operators at the client's end who simply cannot digest that a blend of Oil and Water can do anything positive further hampered the way.
Even when burning perfectly and delivering 3-5 % in fuel economy, it is apparently not enough to satiate their expectations of 20-25% savings. And last but not the least, the rampant corruption in the Indian industries whereby the client's own staff receive monthly pay-offs for accepting heavily adulterated fuel from unscrupulous transporters and dealers, makes sure that they would be the first people to denounce Emulsified Fuel as substandard.


7. What are the limitations of your E.F.O?

A.
It is very important that our E.F.O is not Pre-Heated above 85 Degrees as it would then ruin the stability of the emulsion. Secondly due to its nature, it has a temperature limitation of about 1100 degrees, meaning it is unsuitable as a fuel for applications requiring temperature higher than 1000 degrees, unless there is a very skilled and trained person manning the burners.

8. What changes need to to be implemented to start using your E.F.O?


A. If your Equipment is already firing Furnace Oil, absolutely no changes are require , though we recommend a thorough cleaning of the service tank and filters to get rid of the previous sludge as a precaution. Same is in case if your equipment has a Dual Fuel Burner which can fire both Heavy Fuels & Gas or Heavy Oils & Lighter Oils(Diesel /LDO).
However, if your Equipment is currently only using Natural gas or Diesel as its Fuel, than the Burners would have to be changed and a Heavy Oil "Heating and Pumping Unit" installed along with fitting a heater in the service tank.
Our team of specialists can help you in advising the required changes.
