Reproducible flame setting

For M.A.S. burners the important factors for flame shape adjustment is the setting of:

Scale number (long or short flames),
M.A.S. air pressure (sharp or soft flames)
and pressure of central air

Scale number

Scale number on flame setting device

increase or decrease
by actuation of a crank

long to short flame

Pressure of central air

Pressure-flow setting of central air

increase or decrease
by valve setting

combustion quality

Pressure of M.A.S. air

Pressure-flow setting of M.A.S. air

increase or decrease
by valve setting

sharp to soft flame

The simplicity of the adjustment function provides a high degree of reproducibility even when a lot of different fuels are fired or conditions out of any reason would change.

The operator only has to adjust:

pressure (flow) of M.A.S. air
scale number (deflection of M.A.S. nozzles) on the scale of the flame setting device
pressure (flow) of central air
