4.2. Control and safety elements of the boiler
The control and regulation of the boiler is governed by a control unit - see separate instruction manual.
Safety components that monitor the safe operation of the boiler:
•
The emergency thermostat is used to prevent the system from overheating. The manufacturer sets
the thermostat at 95°C, i.e. at a higher temperature than can be set on the boiler. The emergency
thermostat is positioned on the rear wall of the boiler in the CLIMATIX control unit cabinet.
•
Thermal protection of the motor (thermal contact) is part of both fuel feeder motors and is used to
protect them from overheating in the case of fuel feeder blockage. It also retroactively stops the fan so
as to avoid burning of fuel in the container in the event of a fault. During normal operation, the motor
working temperature is up to 85 °C - such warming does not mean a failure.
•
The turnstile is a device that mechanically separates the fuel between the screw conveyors (feeding
from the bunker + feeding into the boiler). In the event of re-ignition of fuel in the boiler feeding (e.g.
during long term power outage) the fuel in the tank does not ignite. Furthermore, the turnstile serves as
a partial fuel crusher. In the event of a longer piece reaching the turnstile, the turnstile crushes it into
smaller pieces.
•
The cover limit switch of the bunker feeder shuts down the screw feeder and fan when the cover is
open. After proper closure both will return to normal operation.
•
The emergency fire extinguishing system is another security feature preventing burning of fuel
through to the container. A temperature increase above 95 °C at the feeding out of the bunker results in
a thermostatic valve opening and the space being cooled with cooling water from the water main.
•
The firing flap is located between the second and the third draft in the top part of the finned heat
exchanger and serves to regulate the flue gas temperature at the boiler outlet.
When operating the boiler when the flue gas temperature is higher than 100 °C the firing valve must be
closed, i.e. the firing flap lever on the side of the boiler must be rotated as much as possible upwards
(forwards) and secured with a locking screw. When firing (with cold chimney) or during long term
operation of the boiler at lower output it is recommended to operate the boiler with the firing valve
slightly open so that the flue gas temperature does not drop below 80 °C. In this case, the firing flap
lever must be rotated downward (backwards) and secured by a locking screw.
