Picture No. 7 Burner
The burner body – is a hollow weldment made from highly legated material with a bottom transversal fuel inlet.
The fuel is delivered by a built-in
F2 feeder
driven by an electric motor with a gearbox.
A set of slit and round jets in the burning grill ensures inflow of air in order to facilitate controlled full burning of
delivered fuel during its stay in the burner chamber. The burned out fuel is subsequently pushed over the edge of
the chamber into the ash receiver.
The inner space of the burner body is connected to an
air fan
, whose revolutions can be regulated within a large
range depending on the required boiler output or the type of fuel being used. (See MENU 11.9 Fans – chapter
9.4.9).
Impulse revolution sensor
The gearboxes of the F1 and F2 feeders are equipped with impulse sensors, which ensure safe operation of the
boiler.
Connecting hose to the F1 feeder made of inflammable material connect Feeder F1 and Feeder F2. It is part
of the transfer fuel lines. It must meet strict installation rules:
It cannot have significant folds, which would block smooth fuel movement and must be built with an
inclination of minimum 50º (in a relation to horizontal plane).
