Lechler Laval nozzles atomize liquids as a fine full cone. These twin-fluid nozzles work according to the supersonic principle. A dual-phase mixture is created from atomizing air and liquid in the mixing chamber inside the nozzle.
The shape of the nozzle causes this mixture to be accelerated to supersonic speed, resulting in an extremely fine atomization of the droplets. By changing the air/liquid ratio, the droplet size and the droplet spectrum can be adapted within a wide range.
The large free cross sections of the nozzle also allow atomization of viscous or solids-laden liquids. Choosing the right material prevents wear even where abrasive media are present, and enables use at high temperatures.
The compact and handy design of the nozzle lances makes them easy to assemble. The nozzles themselves have a low-maintanance design and can be quickly cleaned or exchanged with minimal effort.
The nozzle lances are manufactured of high-quality stainless steel and depending on process-specific requirements can also be made of chemical and high-temperature resistant material.
The nozzle lances ensure optimal spray placement and alignment in flue gas ducts. The choice of nozzles and the consideration of local conditions and process-related matters means they can be individually adapted to the respective requirements.
Lechler nozzle lances are available with many options, including but not limited to:
