Fuel variability: In order to ensure the stability of the
combustion and power output of the boiler, a gradual
change in the fuel (heating value Hu, sizes, density,
water content) is accepted, which does not exceed 10%
of each value mentioned in less than 30 minutes.
3.4 Unsuitable fuels
The burning of unsuitable fuels could lead to
uncontrolled combustion. Operational faults and
consequential damage are likely to occur.
Possible consequential damage:
− Damage to the thermodynamic combustion chamber,
the lambda probe, the flue gas sensor and the
combustion chamber sensor due to aggressive
residues in the boiler
− Sooting or corrosion in the filling area due to
condensation as a result of using fuel that is too
moist.
− The escape of flue gas from the airflow apertures
through uncontrolled combustion (deflagrations).
3.5 Fuel change
If you use a different fuel type as specified mind:
• allowed fuels (see clean air act)
• Water content and the fuel size are in
admissible range.
• it is eventually necessary the adjustment of
the blower engine speed and fuel level
adjustments to tune new.
