Complete cleaning
At least once a year, the boiler must be
completely cleaned, completely eliminating ash
and other residues and all encrustations,
especially those that occur in water models.
This procedure is of great importance to
minimize the effects of corrosion. Do not use
liquids for cleaning. If necessary, use a spatula
or wire brush beforehand.
11.4.1. Chimney cleaning
Chimney cleaning should be carried out at least
twice a year at the beginning and middle of the
winter season or when necessary.
This cleaning must be carried out with a 100 mm
nylon or steel brush.
Figure 12- Cleaning brush for pellet equipment
It is worth mentioning the cleaning of the
chimney tee top that must be carried out every
1000 kg of pellets consumed, otherwise the
boiler will start to burn poorly and black liquor
may start to appear, indicating a clogged
chimney.
