Gas conditioning towers are found above all in the cement industry, where they are used to cool hot process gases from the preheating tower to a filter acceptable temperature.
Flue gas is cooled by injection of extremely fine droplets distributed as evenly within the gas flow. Water injection is carried out by specifically designed nozzle lances, which spray water using one of the following principles: High pressure water pulverised by its own pressure, or medium pressure water pulverised by compressed air.
Gas conditioning tower outlet temperature can be controlled by just controlling the injected flow water. AAF-International may supply a complete turn-key installation, including complete mechanical and electrical installation, water injection and control system.
