2.4 A fire hazard
With insertion-type firing systems, the conveying
route creates a connection between the silo and
the burning material in the boiler plant.
With the PYROT
insertion-type heating boiler, the
feed auger is also the metering auger, and is thus
always filled up with material during operation
There are various safety devices provided to pre-
vent burn-back.
Temperature sensors:
By means of temperature sensors on the feed au-
ger, in case of excess temperature the loading to
the feed auger is interrupted, and the feed auger's
material is inserted into the combustion chamber.
Slide valve (optional):
This closes in case of a standstill, danger of burn-
back or power failure (spring return motor).
Rotary valve (optional):
Instead of a slide valve, in silos with pressurisa-
tion.
Drop-off route:
A vertical drop-off section interrupts the con-
nected line of burning material.
Fire-extinguishing system (option):
This system, which functions independently of the
electrical power, brings about a flooding of the
material to be burned that is located in the feed
auger. The activation temperature is approx.
95°C.
2.5 Wood fuels, minimum requirements
The PYROT is only suitable for incinerating the
fuels listed in Spec Sheet 1010 "Minimum Re-
quirements for Wood Fuels" (see supplement).
If different fuels are used, KÖB will not as-
sume any liability for the functioning or ser-
vice life of the boiler plant. Refer to the "War-
ranty" section in the General Terms and Con-
ditions of Delivery.
2.6 Filling the fuel storage unit
2.6.1 By dumping
Rotary sweep extraction and spring-operated
extraction
Heating system in operation:
-
If the articulated arms or spring-mounted
plates are still covered by fuel, refilling can be
carried out immediately.
-
If the articulated arms or spring-mounted
plates are no longer covered by fuel, fill the silo
evenly to approx. 30 cm above the articulated
arm or over the spring-mounted plates. As
soon as the articulated arms or spring-
mounted plates have retracted through a re-
quest for material, the refilling can be contin-
ued.
Heating out of operation:
- If the articulated arms or spring-mounted
plates are still covered by fuel, refilling can be
carried out immediately.
- If the articulated arms or spring-mounted
plates are no longer covered by fuel, fill the silo
evenly to approx. 30 cm above the articulated
arm or over the spring-mounted plates. Then
activate the "SILO FILLING" function. To do
so, press the LOADER SYSTEM key (F4) and
then the left arrow key (<). Then select "YES"
and confirm with "OK". Wait until the articu-
lated arms or the spring-mounted blades go
under the cup washer, and then finish evenly
filling the silo. The "SILO FILLING" function
brings about the filling of the fire box.
NOTE: The "SILO FILLING" function cannot be
activated until the heating system has been
out of operation for one hour.
Moving floor conveyor
-
Fuel can be refilled automatically.
Funnel extraction system
-
It is mandatory that the heating system be in
operation!
2.6.2 By blowing in
The heating system has to be out of operation
(danger of excess pressure or negative pres-
sure caused by the action of blowing-in). Fill-
ing procedure as described in section 2.6.1.
2.7 Correcting malfunctions in the feed sys-
tems
The cause of motor malfunctions in feed systems
is usually clogging by large pieces of wood or for-
eign matter.
CAUTION
DANGER OF INJURY:
Always turn off the master switch before car-
rying out any repair of a malfunction on feed
systems and every time before a maintenance
lid is opened or a protective device is re-
moved!
The automatic operation of the system makes it
impossible to foresee the time point when the
conveying equipment will switch on.
