Lechler VarioJet nozzles atomize according to the principle of internal mixing. With this twin-fluid nozzle, the water is fed in axially via a bore hole. The liquid is split up into a thin liquid film. This thin liquid film is split into finest droplets by the atomizing air in the mixing chamber. The resulting two-phase mixture is then atomized a second time when exiting via several bore holes arranged in a circular fashion.
Thanks to the innovative design of the nozzle, a spray with a large outlet angle is achieved. This is characterized by an even liquid distribution as well as a fine droplet spectrum with a low specific air consumption. The large free cross-sections in the nozzle keep the risk of clogging and the maintenance effort to a minimum.
The fineness of the droplet spectrum is decisively influenced by the air/liquid ratio and by the pressure level of the two flow rates. As a general rule: the higher the air/ liquid ratio and the higher the pressure level of atomizing air and liquid is, the finer the droplet spectrum.
Nozzle lances ensure optimal spray placement and alignment in flue gas ducts. The consideration of local conditions and process-related matters means they can be individually adapted to the respective requirements.
The robust, high-quality stainless steel construction ensures a high degree of functional reliability. Lances are avialable in a variety of material to suit specific process requirements.
The nozzles themselves have a low-maintenance design and can be quickly cleaned or exchanged with minimal effort.
Nozzle lances are available with many options,including but not limited to:
