Narrative:

On climb out at 800 ft, we had an engine overheat. We retarded the throttle slightly and the engines indications went to normal. At about 6000 ft, #3 engine fire indications sounded. Also, the #3 engine start valve light came on. We proceeded with the appropriate checklist, declared an emergency with tyo ATC. We fired both bottles with no results. The fire indications continued and we immediately returned to nrt (dumped only about 27000 pounds) and landed at about 730000 pounds. Brought the aircraft to a slow roll to clear the runway and had firemen check the engine, then slowly the fuse plugs melted, as we helplessly stood by.
