Due to their different efficiency-related design methods, nozzles for flue gas desulphurization are differentiated according to the following criteria:
The most frequently used nozzles in Air Quality Control Systems (AQCS) are hollow-cone and full-cone nozzles. Hollow-cone nozzles produce a circular load; full-cone nozzles, on the other hand, distribute liquid over a circular area. Helix nozzles occupy a special position.
Hollow-cone and full-cone nozzles with tangential inlet flow do not have any internals. The hydrodynamic design results in a self-cleaning effect and thus trouble-free operation of the nozzles. However, axial full-cone nozzles of the various series also have the largest possible passage cross-sections due to a specific swirling design.
An important factor in nozzle assembly is the time required for installation and removal, i.e. the downtime of the system. Lechler therefore offers different mounting variants tailored to customers’ requirements, which help to save time and money. Lechler offers various fastening solutions according to the supply lines of customers system.
