In order to ensure the failure-free and safe operation (to maximum extent) the
controller of boiler is provided with many protection functions. If faulty status is
discovered, the alarm is launched (acoustic signal), and a message is shown on
display (depending on controller version).
THERMAL PROTECTION
The controller is equipped with safety temperature limiter, preserving the boiler against
overheating
(boiling water in installation), if the controller is damaged. Temperature
limiter makes up mechanical protection measure, which is bimetallic sensor (placed
at the boiler water temperature sensor) cutting off power supply to blow-in fan and
fuel feeder, if temperature is higher than 90°C (pump still working).
TEMEPERATURE PROTECTION
The controller is equipped with additional temperature protection (electronic
one), for the case of bimetallic sensor is faulty. If temperature of 95°C is
exceeded, cutting off power supply to blow-in fan and fuel feeder is executed.
FUEL BUNKER PROTECTION
A controller is additionally protected against
flames getting back into fuel
bunker (hopper). Boiler is provided with sensor measuring temperature around
hopper’s vicinity. If temperature raise is significant (flames back) an alarm is
launched and fuel is pushed out into combustion chamber.
SAFETY VALVE
Boiler is provided with safety valve being an additional protection against
pressure raise due to water freezing in part of installation, especially in the pressure
vessel.
Commercially delivered boilers are assembled and supplied with complete set
of tools for maintenance together with the technical-start-up documentation. Before
connecting a boiler to a heating installation, make check if all boiler’s components
are in good working condition, and that the boiler is fully equipped.
NOTE: Boilers need to be transported in the vertical position!
