tnePatAdvanced Technology for efficient
Flue Gas Desulphurization■ Increased desulphurization■ Increased efficiency■ Decreased operating costs■ Decreased maintenanceTwinAbsorb®-EVEquilateral
Full Cone Nozzle

TwinAbsorb®-EH
Equilateral
Hollow Cone Nozzle

The proven equilateral Full
Cone Nozzle TwinAbsorb®EV generates two fullcones by using one single
supply.

The proven equilateral
Hollow Cone Nozzle
TwinAbsorb®-EH generates
two hollow cones by using
one single supply.

Advantages■ Provides smaller Sauter
diameter (SMD d32) causedby dual cones.
■ Particularly advantageous
not only for high flow rates
per nozzle.
■ Improved mass transfer
caused by increased
specific surface area.
■ Supports an even gas
distribution over thescrubber cross-section.
■ Rotation impact onto thegas flow is compensatedwithin the nozzle.
■ Better coverage of scrubber
wall section.
■ Reduced slurry loss at thescrubber wall in comparison
to hollow cone nozzles.
■ Reduced stress at scrubber
wall in comparison tohollow cone nozzles.
■ Reduced torque onto thepipe branches.
■ Keeps the advantages ofLechler tangential flow fullcone nozzles- completely self draining- large free passages- non-clogging designed

Advantages■ Provides smaller Sauter
diameter (SMD d32) causedby dual cones.
■ Particularly advantageous
not only for high flow rates
per nozzle.
■ Extra overlapping area forhighly intensive secondary
atomization.
■ High efficient generation of
new stimulated reaction
surface without additionalenergy input.
■ Increased turbulence within
the drop achieves reactivity of reaction surface.
■ Improved mass transfer
caused by increased
specific surface area.
■ Rotation impact onto thegas flow is compensatedwithin the nozzle.
■ Better coverage of scrubber
cross-section.
■ Reduced torque onto thepipe branches.

TwinAbsorb®-HBi-directional
Hollow Cone Nozzle

The proven bi-directional
Full Cone Nozzle
TwinAbsorb®-V generates
two counter rotating fullcones.

The proven bi-directional
Hollow Cone Nozzle
TwinAbsorb®-H generates
two counter rotating hollow
cones.

Advantages■ Improved mass transfer
caused by higher relative
velocity of liquid to flue gas.
■ Rotation impact onto thegas flow is compensatedwithin the nozzle.
■ Increased turbulence within
the drop for highly active
reaction surface.
■ Increased residual time ofdrops during the process.
■ Duplication of hydraulicspray level in comparison
to single spray nozzles.
■ Reduced pressure loss incase of counter current gasflow.
■ Reduced slurry loss at thescrubber wall in comparison
to hollow cone nozzles.
■ Better coverage of scrubber
wall section.
■ Provides smaller Sauter
diameter (SMD d32) causedby dual cones.
