Pic.6. Feeder’s auger installation.
Fuel dosing is done automatically. Feeder operation is cyclic and is operated by outer controller.
Feeder should be positioned at maximum 45º angle in relation to the floor. Flexible, antistatic
polyurethane pipe must not be directed vertically above the pouring chimney of burner, but at
least 30 cm away from it. In case of pipe overheating (back burning) or its melting, pellet fuel will
not be falling onto burner. Lack of fuel supply will cause burning off. It prevents against spreading
fire on fuel hopper and on the rest of boiler room.
NOTE: Before starting the burner, fill the hopper with pellets and fill the feeder until
pellets will start falling into the burner.
3.5. STB protection
In case when oven or boiler does not have its own STB protection, a thermostat with a
capillary on clips is added to the set. Capillary sensor should be permanently mounted in water
coat of the boiler. After reaching critical (95
o
C) temperature of boiler, fuel feeder is cut off. In case
of restarting the burner the switcher on cover should be reset, before that the cause of
switching off due to boiler overheating should be checked, assessed and right steps to solve the
cause of the problem should be taken.
3.6. Boiler temperature sensor
Burner is provided together with boiler temperature sensor. Its task is to control firing up and
burning off process in burner.
It does not refer to burner version destined for bakery
ovens.
