Properties and Advantages of the ROCKTEQ Multi Channel Burner system

Venturi-Effect
The high exit velocity of the primary air at the burner tip (Venturi effect) guarantees a very
good
interference of the secondary air - approx. 85% of the whole combustion air - and
a high external recirculation.

Optimal Combustion

An optimal combustion of coal is achieved by mixing oxygen into the flame core.
Due to the position of the coal pipe, which is located between axial and swirl air.
Therefore coal as supporting fuel for the solid secondary fuels guarantees a hot
and short flame.
   

Less heat load

The high axial air proportion improves the flame shape and reduces the heat load in
the kiln outlet area. Thus the fire-resistant wear of the kiln lining is also reduced.

High residence time

Central air and swirl air generate an optimum internal recirculation with correspondingly

high residence time for the combustion of solid secondary fuels.

Supply and flame shaping

Concentric supply of all fuels and primary air. The primary air (axial air, swirl air and
central air) is supplied
by three separate concentric ring channels, is measured and
effectively regulated by simply adjustable flaps
– thus a reproducible flame shaping
can be realized. The triple supply of the air allows an optimum
setting of the flame
shape. By means of the good mixture of air/oxygen and fuels a short turbulent
flame
will be achieved.
