MAKING MODERN LIVING POSSIBLE

Basic considerationsThe latest technology in efficient hea-ting technologies, such as condensing boilers, is often combined with rene-wable energies such as solar systems or bio fuels. Normally, low-sulfur hea-ting oil is mixed with a certain percen-tage of bio diesel (FAME Fatty Acid Methyl Ester) to produce such bio fuel.

The bio proportion is produced from rape seed or sunflower oil which un-dergoes a chemical process to make it look like normal heating oil. Using bio fuel is not problem-free and can place certain demands in the materials used from oil tank to oil nozzle. First, the burner itself must be suitable for bio fuel and the pipes, filters and hoses need to be adapted and last but not least, oil pump, oil preheater and oil nozzle should be suitable for use with bio fuel. Danfoss has carried out ex-

tensive studies in order to offer com-ponents fit for this new oil.

Since early 2010, Danfoss has offered the service components suitable for B10 and in February 2011 all new oil burner components from Danfoss were released for use with B10. B10 is the term for bio mixtures containing up to 10.9% bio diesel. This is rated ac-cording to the German standard DIN V51603-6.

What about existing oil burners? In Europe there are around 12 million oil burners in operation and a large proportion of these use Danfoss Bur-ner Components. The vast majority of these burners have been in operation for many years and have three impor-tant components to take into conside-ration when switching to bio fuel.

The Danfoss nozzle is exchanged re-gularly and thus will not cause any dif-ficulties. The Danfoss preheater has a long life and will not be worn. The materials used for the preheater have always been appropriate for use with B10, as it happens to be the same materials that are suited for higher temperatures which are also suited for bio fuel. This means that the Danfoss nozzle and preheater can be used with the new bio fuel B10 completely unchanged.

The situation is quite different when it comes to the Danfoss oil pump. The materials previously used for this pro-duct can only handle a B5 mixture, i.e. 5% share of bio fuel in the heating oil. As a result of the previously mentioned studies, Danfoss has chosen to equip all its pumps with FPM (Viton ®) seals. This means that you can upgrade your oil burner by replacing the oil pump with a new BFP service pump.

Which type of oil can the user then put in the tank?Initially you should ask the supplier of the burner system if it can run with bio fuel. Then you must ensure that the entire system is suitable for this new oil, i.e. the tank pre-filter, pipes and hoses should be bio ready. The burner manufacturer or the installer may be helpful in determining whether the installation is suitable for switching to bio fuel.

Bio fuel has some unfortunate charac-teristics that over time may produce a varnish-like precipitation in the pump, preheater and nozzle. If the bio fuel does not completely follow the regu-lations it may lead to a shutdown of the oil burner. This kind of downtime is obviously outside of the product warranties which Danfoss can provide.

PRODUCT INFORMATION

Using bio fuel in oil-fired systems

The location was carefully chosen. Right where it all be-gan, where Danfoss has its roots and the company founder Mads Clausen was born and grew up. With an investment

of 17 million Euro, the technology park „Danfoss Universe” has emerged and is enjoyed by approx. 200 000 visitors annually.

One of the main goals of the park is to catch the interest in technology of children and young people. In order to do this, you really need to reach the parents as well, and the park is suc-ceeding in this. Visiting Danfoss Uni-verse the whole family has fun and at the end of the day is smartened up in terms of science. Children and adults learn through play – jumping from one experiment and exciting natural phenomenon to the next. Did you ever want to try for yourself to dig

sand with a real excavator or test your „multiple intelligences“?

The trip through forces of nature and laws of physics begins at the Blue Cube, the former Icelandic pavilion at the Expo 2000 in Hannover. Visi-tors experience how a geyser shoots up 18 meters high in the air, walking through the glacier and experiencing lightning and thunder close up. In the spectacular exhibition building, Cumulus, children and adults can play with digital technology in a new and different way, fighting robots or creat-ing your own animated cartoon.

At EnergyLab you can play with dif-ferent energy forms in a mixture be-tween indoor and outdoor activities – bring extra clothes or a towel if you go here, as there is an opportunity to get wet at the solar cell fountain. If your legs tire out, jump on to a Segway and experience a technology, where com-puter force, design and bodily interac-tion are combined.

All in all, Danfoss Universe offers more than 200 fun and instructive activities – visit our website for more information here: http://uk.danfossuniverse.com

What do you think of our Newsletter?

The Danfoss Burner Components Newsletter has existed for 18 months now with 8 issues. We therefore feel that the time is right to ask for your opinion, and hopefully find out if we are bringing the information you would like in our newsletters.

It pays off to contribute!Please let us know your opinion, ide-as and wishes. Simply e-mail us your comments or suggestions to improve our Newsletter for you: mailto:Burner@Danfoss.com

The 10 first contributors will receive no less than a digital camera. Thank you for your considerations! :-)

At the world’s leading trade fair for Bathroom Experience, Building, En-ergy, Air-conditioning Technology, and Renewable Energies, customers from around the world were excited to see our Solutions Ready displayed in a completely new exhibition concept.

The touch screens which showcased small videos, photos, product features and system functionalities were very well received. To view our animation, please follow this link: Product Animation

The main interest in the area of Burner Components was our innovative mo-tor pump unit, type BFPM, which was also exhibited within some of our cus-tomers’ solutions.
