Narrative:

Engine fire warning on climb out houston. 6000 ft declared emergency return to hobby. No problems. Callback conversation with reporter revealed the following information: the reporting pilot did not have a fire, just an overheat caused by the anti-ice ducting breaking loose ahead of the anti-ice valve allowing very hot air to be ducted inside the cowling and outside the engine. Most of the wires in a bundle that brings engine information to the cockpit were badly burned. His air carrier's procedures do not require an engine to be shut down if the warning light goes out when the throttle is closed. This was the case in this incident. The aircraft was a DC9-30 with JT8D engines. The engine was shut down after the aircraft landed. There was no other damage.
