heat transfer, In addition, for safety reasons a pictogram and a message on the
nameplate was used that informs the user about uninsulated hot elements –
(flue pipe).
The moving parts (gear motor, sprocket mechanism and chain driving the
fuel feeder, moving grate drive, blowing fan) located underneath the hopper was
secured against direct access with detachable shields. Furthermore, for safety
reasons, a pictogram informing a user about presence of the mobile components
was used.
The fuel tank is provided with a loading opening with sealing and a closing
system. The design of the tank equipped with the hopper ensures free transport
of fuel (gravitational discharge). In addition it is fitted with a limit switch that stops
the blowing fan operation and fuel feeder after opening the cover! (See fig. 6) A
message appears on the display:
„Cover Open”
and an
audible alarm
is heard
(reminder and signal appear cyclically for a few seconds). When the fuel reservoir
cover is closed, the operation is resumed. Inside the cover there is an information
for the user about the presence and operation of the limit switch (reservoir cover
opening sensor).
NOTE:
Due to the installation of the limit switch, the fuel reservoir cover must al-
ways be sealed (during normal operation of the boiler)!
Directly above the furnace and on the side wall of the boiler opposite the SAS
MULTI FLAME burner the heat exchanger chamber has horizontal/vertical parti-
tions made of refractory ceramic material increasing the combustion temperature
and reducing the emission of harmful gases into the atmosphere. The number
and layout of horizontal ceramic partitions over the furnace is dependent on the
power of the boiler.
Additionally, the exchanger is equipped with a gas turbulator which forces hot
flue gas whirl and enhanced transmission of heat to the heat exchanger. The flue
gas impacts the turbulator walls, causing the dust fall to the bottom of the boiler.
The dust can be removed by side clean outs of the heat exchanger chamber.
