Burning pellets in a normal wood stove?

Sort of.   They would burn, no doubt, but they may not burn as well as wood
because of the configuration.  If you were to just pour a pile of them in
the stove and light it, the pile would not have good air circulation and the
pellets would smolder and maybe die out once the ash on top smothered what
was left.

It may be possible to mix in some along with the logs, but that would take a
little practice to get the right mix.
