You may see it for a window air conditioner in a home or an air compressor in a shop. I put them in for refrigeration units. The receptacle does not have to be the single 20 amp 120 volt type, it could be a standard duplex receptacle if you want to change it. The 20 amp 120 volt single actually looks like the one on this page, it's a NEMA 5-20R:

Yes -- the type you show below.

Exactly so. If a 20A circuit has only one outlet, it must be a 20A outlet as shown. Note that a duplex receptacle is considered to be two outlets, and thus a 20A circuit is permitted to have a single 15A duplex receptacle.
