Can I power things even after Zener breakdown?

I understand that Zener Breakdown occurs when the reverse current starts flowing in the junction because of which depletion region entirely vanishes. Can I power things using this reverse current ? Or will it damage the appliance?

Can you be more detailed in what you are asking, and post some schematics?

Zener diodes are usually used in shunt configurations, to provide crude voltage regulation. You can use them in series with a load if you want to drop some voltage (the Zener voltage) between your voltage source and the load. Your Zener diode needs to have a power rating sufficient to handle the $I_s V_z$ (series current * Zener voltage) power dissipation, of course.

I am referring to reverse current in zener breakdown. I am referring to this part.

Of course. That's how a Zener diode works.

Image link is not working for me. Maybe just paste in the image into a reply? (You'll need to be sure the little Edit icons are not red, but clicking the "[ ]" toggle BB icon if needed)

Or are you not referring to a Zener diode, and are referring to some other semiconductor device?
