In the case of certain gas-cleaning processes, particularly in the cement industry, it may be necessary to cool down the gases prior to the cleaning process or to condition the gases to the most favourable physical state.
The operating principle of an evaporative cooling tower system is simple. By injecting water in very fine droplet sizes which are subsequently evaporated, the temperature of the waste gas is lowered to the necessary level and its volume and the specific resistance of the dust in the gas is reduced. Optimal dimensioning of the individual components of the installation provides top efficiency.
General operating data for evaporative cooling towers:
•    Temperature range inlet: 250 - 1000 °C
•    Temperature range outlet: 120 - 300 °C
A "feedforward" control can be used if a 'constant as possible outlet temperature in combination with rapidly changing conditions of entry temperatures' is required.


The essential components of an evaporative cooler are:

1 Gas inlet cone with gas distribution internals 
2 Cooling tower casing in which the exhaust gases are cooled and conditioned by evaporation of water
3 Integrated mixing zone in the cooler which, in special cases, is attached to the evaporative section
4 Dust collection hopper
5 Water spray system with spill-back nozzles or, alternatively, air atomising nozzles    


The perfect design of the evaporative cooler and its adaptation to the target specifications of the installation are decisive elements in reaching the maximum degree of efficiency and a long life of the entire plant.
