With feeding burners there is a connection, created by the transport path, between the
burning material in the boiler and the fuel store.
With the PYROMAT DYN heating boiler, the feed auger is also the dosing screw and is
therefore always completely filled with material during operation.
To prevent back burn the following safety devices must be installed, according to the
country-specific regulations:
If the temperature sensor on the feed auger detects an increased temperature then the
supply to the feed auger is interrupted and the material in the feed auger is fed into the
combustion chamber.
Closes when the system is shut down, if there is a danger of back burn or if there is a
power outage (spring return motor).
Engagement of the slide valve in the silo with pressure application.
The burning material connection is broken by a vertical drop.
This device, which operates independently of electrical power, floods the fuel material
in the feed auger.
