Narrative:

Departure from ord while setting climb power, #1 engine froze at approximately 80% N1. Could not increase or decrease power by throttle movement. Returned to ord and made a precautionary landing. After landing I shut down #1 engine. ATC was very helpful in getting us back into ord as quickly as they could.
