An environment-friendly, emulsified fuel, called EM-fuel, suppliedby environmental technology company Nano Bubble Technologies (NBT) is able tolimit carbon build-up in boilers, reducing maintenance and harmful emissions,the company reports.
The low-cost EM-fuel is produced by combining petroleum-basedproducts or plant oils with water and emulsified fuel additives.
The EM-fuel has the same consumption rate as paraffin or diesel andNBT also offers diesel and paraffin emulsions.
EM-fuel is an emulsion of 80% fuel and 20% water that creates a new fuel that surpassesall US Environmental Protection Agency emission regulations, states NBT.
The product is stable for up to six months in normal temperatureconditions.
Used in boilers, the EM-fuel limits carbon build-up in piping, asthe fuel burns more efficiently and the combustion process also becomes moreefficient.
NBT sales manager KarlHenriksen says, with continued use, the fuel also cleans away existingcarbon build-up.
“Customers have found that, after three or four weeks of using thefuel, they use less fuel than normal, as the boilers are "cleaned" of the carbonbuild-up that suppresses heat efficiency,” he explains.
Carbon build-up effects heat transfer efficiency. As a result ofthe build-up, more fuel is used to heat the pipes inside the boiler but thecarbon build-up in the boiler causes poor heat transfer quality.
This decreases the boiler life span and increases the need for maintenance.This directly hampers production and costs companies money.
Meanwhile, another benefit of using EM-fuel in boilers is improvedpump lubrication. Lubrication adds between 2c/l to 8c/l to companies’fuel bills. With the EM-fuel, no added lubrication is needed, as the fuel containsdouble the amount of lubrication that diesel does.
Pumps are better lubricated and less heat and friction extends thelife of the pumps.
“We try to save the client at least 5% on fuel consumption. If theclient utilizes a fuel-mixing machine from us,fuel savings can increase to as high as 20%. In some cases, we have also seen a60% reduction in harmful emissions and particulate matter,” Henriksen says.
Further, he says preventing pilfering is a secondary benefit of usingthe EM-fuel, as the product is white and does not look like conventional fuel.He suggests that it would be hard to steal and resell, as the average personwould not know the product was actually fuel.
Meanwhile, NBT gives companies the opportunity to mix their own fuelon-site.
“We supply machines, called EM30sthat mix and produce the EM-fuel for customers on site. One machine costs aboutR1-million but the customer only pays for every litre of fuel that is converted.We manufacture these machines at our depot in Cape Town,” reveals Henriksen.
The machines are able to produce 30 t of fuel in a 24-hour cycle,he says.
The company’s Cape Town facility has the capacity to produce 500000 l of EM-fuel, which is thensupplied to smaller companies.
NBT has five plants in operation across South Africa on customer’ssites and the company has recently opened a branch in Johannesburg thatproduces and sells fuel. The company is hoping to find ‘franchisers’ across thecountry.
