The
FIB constant mixer is a static device that operates in combination with a
BZR gas governor to automatically provide a mixture of air and gas. The ratio
between the two constituents remains constant over a range of flow rates varying
from 1 to 15.
Acting only on the flow of air, it automatically mixes the gas in the correct
proportions over the entire range of flows.
The FIB constant mixer is also a proportional mixer that furnishes a mixture
of constant composition , independent of the pressure in the collector supplied
by the mixer and of the cross – sectional output of the burners, or
of the number of burners supplied by this collector.
As a result:
- The “Constan mixer” can operate at any mixing pressure. Thus,
there is no constraint to the operating pressure;
- With the “Constan mixer”, a number of burners and variations
in the flow rates to those burners can be accommodated, without the need to
adjust the proportions of air and gas that remain constant;
- The proportions of air and gas supplied by the constant mixer are not affected
by the variations in pressure that may occur in a furnace.
