4.8 ECOLOGICAL OIL BURNERS
WARNING
The transition from normal fuel oil to ecological fuel oil requires:
The tank to be emptied of normal fuel oil.

 Cleaning of the tank and the pipes that carry the fuel oil to the burner.
 Application of a filter if there is not one already on the burner fuel line with a filtering grade of 0.3 mm maxi-
mum.
If this is not done, Riello S.p.A. declines all liability if the burner fails to work properly or wears out prematurely.
NOTES
These burners are the result of careful study that allows them to be used with ecological fuels as well; oils, that
in certain temperature and speed conditions, are particularly aggressive for the vital parts of the burner.
The objective has been achieved with the reduction of the transiting speed in some of the parts and an appropri-
ate choice of materials (in particular surface treatments) as well as a redefinition of the backlashes and coupling
tolerances.
The burners for ecological oils are very different from normal fuel oil burners because they have a separate
pump (worked by its own motor at 1400 rpm) and the fact there is double filtration between pump and nozzle.
4.9 EMULSIFIED FUEL OIL OPERATION
