4 Function
The burner control unit opens the gas and air control valves.
Gas flows through the gas connection flange and air flows
through the burner housing as far as the nozzle-mixing burner
head.
The combustible gas/air mixture is produced downstream of
the burner head. Slots and holes in the air disc vary the degree
and manner of twisting of the combustion air and determine
the flame geometry. Depending on the gas type, the geometry
of the gas nozzle varies.
The gas/air mixture is electrically ignited directly by an ignition
electrode or an ignition lance. A flame forms which is
monitored using an ionization electrode or optionally using
the UV sensor.
The choice of the respective combustion chamber material
and geometry is primarily determined by the process.
Using burner quarls, almost any flame shape and outlet velocity
can be achieved.
For low-temperature applications, a combustion chamber
made of heat-resistant steel can be used. The flame burns
inside the metal burner attachment tube.
