Primary Air Feeding

Primary air is internally divided in M.A.S. air and Central air. Cooling air for any application (cooling of fuel oil lance, coal or gas channel ...) is taken from the burner's central air channel.

Standard execution

is to equip the bruner with
one single radial fan for all purposes.

(internal splitting of M.A.S. air, Central 
air and Cooling air's)

M.A.S. burners are designed to obtain a specific primary air momentum of 5 - 12 N/MW. Operation experience with M.A.S. burners show that small air pressure losses and deep air penetration into the kiln does not require a stronger momentum than 5 - 8 N/MW, for best operation result. Nevertheless we supply burners with higher momentum, more than 8 N/MW on request.
Such kind of burners are either equipped with radial fans or rotary piston blowers for primary air feeding.
