Application

The CALDYN quenching system comprises cooling/conditioning of hot flue gases to a defined temperature, especially before inlet of electro- or bag-filters. CALDYN systems are installed in:

  • chemical, glass or copper industry

  • zinc recycling industry

  • aluminium recycling industry

  • waste incineration plants

  • steel and cement industry

  • power plants

  • biomass plants and wood incineration

Main advantages

CALDYN uses lances with several nozzles. A peculiarity providing many advantages for you:

  • several small nozzles allow considerably shorter evaporation distances and thus smaller tower or duct dimensions

  • low capital investment and operating costs due to optimum individual design

  • the wide range of regulation (1:40) of our plants is excelling other systems especially during start-up and shut-down.

  • little maintenance is required as compared to other systems, using a CALDYN quenching system means:

    • tower and duct walls remain dry

    • lump formations are avoided

    • small temperature variations at gas outlet

  • As the CALDYN atomization system is plugging-free waste water or industrial water can be used without problems.

  • In CALDYN systems the balancing of water flow to the lances necessary when using serveral lances is realized as a standard.

Principle

Flüssigkeitstropfen werden mittels Water droplets are atomised into the gas stream by CALDYN two-phase nozzles CSL. The water droplets evaporate using the heat out of the flue gas.

Lump formations at the tower walls are avoided by using a CALDYN flow equalizer MULTIWIR. MULTIWIR provides a uniform gas flow parallel to the tower/duct axis.

The outlet temperature variations can be reduced down to +/- 5 K by optimal coordination of atomizing technology, temperature measurement, temperature controller and the water regulating system.
