Fuel characteristics
The furnace is first of all characterised by the fact that it burns natural fuel (wood pellets), which are environmentally
derived from waste from the wood industry (chips/sawdust). Once the chips and sawdust which arise in the processing of
wood are properly cleaned and dried, they are compressed under extremely high pressure to produce small cylinders of
pure wood pellets. Each tiny cylinder may vary in length and width from 1 to 3 cm in length and from 6 to 8 mm in the
radius
Wood pellets are primarily characterised by low humidity (below 12%) and high density (= 600 kg/m3), as well as by its
uniformity and compactness, which gives this type of fuel high caloric value (DTV 4100
5000 kcal/kg).
Wood pellets used as fuel for this furnace must have excellent quality characteristics, such as, for example, those
defined by DIN 51731, ÖNORM M 7135 and EN plus A1 standards, for which many basic characteristics are listed below.
⚠
ATTENTION: As is required by the relevant European laws governing the characteristics of commercial fuels, the
pellets must be manufactured exclusively using chips of unprocessed wood, without added substances.
It is strictly forbidden to use any liquid or solid fuel except wood pellets
.
⚠
ATTENTION: In order to operate the furnace at the best level, it is recommended to use the wood pellets certified by
an accredited body. Using other types of pellets compared to those specified by the manufacturer can lead to failure of the
furnace and may void the warranty.
Storage and handling of wood pellets are important tasks that must be performed carefully.
-
The fuel has to be stored in a dry and warm place.
-
Pellets must be handled so as to prevent excessive crushing and turning into a fine powder.
Compliance with these simple rules will allow better combustion efficiency and even help maintain proper operation of
moving mechanical parts.
