…Every time that I do something on a picture in Photoshop the size of the Photoshop temporary file on the hard disk scratch partition grows…
Perfectly normal, expected behavior.
Photoshop always uses a scratch disk, from the very instant you open an image file or create a new document. Always. No exceptions.
…I have set a hard disk partition as a primary scratch disk…
If that's a partition of your boot drive, it's futile and you're much better off leaving the boot drive unpartitioned so as to not limit either the Photoshop scratch disk or the OS swap files. There's nothing to gain because the OS swap files and Photoshop's scratch disk are still competing for the use of the one set of read/write heads.
Bad move. You're just potentially limiting either the Photoshop scratch disk or the OS swap files.

It seems that my Photoshop uses the hard drive as the scratch disk.
correct... PS uses a harddrive as a scratch disk...
Though written for video editing, this ARTICLE on Partitions will have much, that will apply to work in PS with Images too.
Partitons are basically a hold-over from a time, when the OS's could not address larger HDD's. With the possible exception of a dual-boot system, or a very few automatic backup schemes, they actually cause more problems, than they solve.
Separate, physical HDD's will improve things all around, and should also contribute to the life-span of your HDD's.
Right… partitions, shmartitions!

As I mentioned in your other thread, are you finding something wrong with just using the 64 bit edition oF Photoshop, which can make use of all that RAM directly?
Perhaps you could describe what you're trying to accomplish?
Yes, the primary location of Photoshop's memory is the Smart disk, usually, an hard drive.
But the info is cached on memory (for faster access)
Even if the info will be replicated on the hard drive, Photoshop will still use the memory as a cache (a temporary, faster location), 13 gigs in your case.
As scratch files can grow to become huge, the hard drive is used, and could fit as big a scratch as the location you give it.
If you want to speed up Photoshop scratch disk, if you cannot add more memory, adding an SSD as a scratch disk might help, as described in the document linked by R_Kelly.
