FILLING THE HEATING INSTALLATION
Table 7
Problem
Prevention
Possible installation damage due
to strains in the material caused by
temperature differences
Fill the heating installation only in cold conditions
(inlet temperature must not exceed 40 °C).
Danger of installation damage due to
accumulation of deposits
Condensate formation and tar
deposits may shorten boiler’s
operational life.
-
Do not operate the heating boiler for a long
period of time in partial load mode
-
The temperature at the boiler inlet must not
be less than 65°C, boiler water temperature
must be between 80 °C and 85 °C.
-
Use the boiler for a short period to heat warm
water in the summer.
9. OPERATION OF BOILER
Failure to observe the installation
and operating requirements
described in the manual and
the service booklet voids the
warranty.
9.1. Operation of Dual chamber
CombiBurn DC-A
•
IGNITION.
After the start up of the
boiler from the control panel, the main
pellet auger conveys certain amount of
fuel from the pellet hopper to the burner.
This specific amount of pellets is set by
the installer and depends on the fuel
characteristics. The fed-in quantity of
pellets is being ignited using hot air.
•
BURNING.
The burning process takes
place in the combustion chamber and,
after it has been fed into the combustion
chamber, the fuel is then transported
from the internal auger conveyor to the
combustion chamber in portions. This
allows for constant and optimal burning
rate of the fuel. Fuel combustion is
monitored by a temperature sensor in
the exhaust gases, which reports the
combustion and submits information to
the control unit for a possible start or
interruption of the combustion process.
The output of the burner is determined by
the intervals preset on the control panel
taking into account the heating value, size
and density of the pellets.
•
AUTOMATIC CLEANING SYSTEM
.
The
Dual chamber boiler DC-A is equipped
with innovative automatic cleaning
system for combustion chambers of both
divices.
A powerful cleaning motor built in the
burner body, air is being blown in at high
speed and rate thus removing all residues
– ash, noncombustible inclusions, etc.
built up into the combustion chamber of
the burner.
At the same time the boiler turns
on automatic ash removal which is
transported to the ash container through
screw located in the lower part. These
automatic cleaning cycles last several
seconds and can be additionally adjusted
as well as their repeat rate depending on
the load of the burner.
