Narrative:

Departed from gate with a completely full aircraft. Taxied south on taxiway K for runway 36R departure. As soon as we turned onto B we were chimed from the cabin and received a report of smoke in the cabin. I pulled the aircraft onto the ramp area of the a terminal and stopped. I had the first officer opened the door to see the situation. He reported significant smoke. I decided the best action was to make an expedited taxi back to a gate to get the people off while requesting the emergency equipment. We did declare an emergency. I wanted to try to get to a gate as it was 100 deg OAT and an evacuation had it's own hazards. We turned the packs off which did stop the smoke from getting worse. We reached a gate very quickly and deplaned the people without incident.

Original NASA ASRS Text

Title: An MD-82 pack overheated during taxi-in and filled the cabin with smoke; so the crew declared an emergency and returned to the gate where passengers were removed on the jetway.
