Narrative:

On landing rollout, mem tower reported smoke coming from right engine. We exited runway 36R on taxiway S3 and cleared runway. Set parking brake and ran 'engine fire on ground' emergency checklist. Fired 1 halon bottle into engine. Requested the crash fire rescue equipment equipment. Tower advised no more smoke from engine observed. Crash fire rescue equipment guys did a close-up inspection while I made a PA to the passenger just before crash fire rescue equipment got there. We taxied normally to the gate and had the trucks follow us to the gate until the people had deplaned. A mechanic later told me we had a broken fuel manifold internally in the engine. He said we were lucky we did not have a full blown engine fire. The event actually went quite smoothly and I don't think I would have made any decisions differently.
