Removal of potassium chloride

  1. Aug 13, 2013 #1
    I have some problem with potassium choloride(KCl) which got stuck on metalic nozzle at high temp.(above 750C)

    how could I get rid of KCl with minimum expense?

    Plz help!! thanks.

    Dissolve it in warm water.

    Thanks. Baluncore.
    While the process is in operation above 700℃, there is no way to dissolve KCl by water. Steam injection might help?

    Is it a biproduct of the process, or can it be removied prior to being heated to 700 C?

    The “got stuck” in the OP suggested the past tense.

    What is the temperature and cycle time of the jet?
    Is this an ongoing problem?
    What industry?

    Molten salt baths used for heat treating metals may have similar problems.

    Welding flux is naturally released on cooling. If the metallic nozzle had a different temperature coefficient to KCl then it would shed the KCl as it cooled below 770°C.
