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)

Scale number on flame setting device

increase or decrease by actuation of a crank

long to short flame

M.A.S. air pressure (sharp or soft flames)

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

increase or decrease by valve setting

sharp to soft flame

Pressure of central air

Pressure-flow setting of central air

increase or decrease by valve setting

combustion quality


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
