Better solvent for KCl than water? In my experiment, I used an atomizer to generate $\ce{KCl}$ aerosols. I saw that the nozzle that was dipped into the 10% wt $\ce{KCl}$ solution got partially clogged after an hour. I then had to disassemble the nozzle in order to clean it, which I did by rinsing it with water and drying it with a stream of air.
 Is there any way to avoid the clogging?
This seems like more of an engineering problem than "chemistry problem." I'm not sure how long you want the process to run, nor how critical the 10% salt concentration is. 

I'd try adding a pure water bubbler in front of the salt solution to saturate the air being blown through with water.
