Narrative:

We started out with a fuel leak on the #2 engine. Maintenance came out and we ran the engine at idle power. The mechanic signed off the logbook and we deiced the aircraft; then pushed 13 mins late. Early in the takeoff after thrust was set (maximum power due to deicing) we saw a bleed trip light. I elected to continue because thrust was set and there was no other indication of problems. At about 2000-3000 ft; we heard a series of pops/bangs from the left side of the aircraft. Engine indications were erratic so I retarded the #1 thrust lever until it appeared to stabilize. The flight attendant rang the cockpit and we did not answer immediately because we were a little busy right then. When we answered the flight attendant call; she told us the left engine was on fire. We checked the fire warning system and it tested good. I decided to shut down the engine and blow the fire bottle based on the reported fire. We proceeded to intersection for one turn in holding to run checklists; check performance and talk to dispatch. Performance was good for a flaps 15 degree landing at ZZZ (117000 pounds) so we decided to return rather than go to a longer at ZZZ2. We told the flight attendants to secure the cabin for a normal landing; then made a PA to inform the customers. We did an uneventful flaps 15 degree landing that was; I might add; quite impressive.

Title: B737 HAS ENG FAILURE SHORTLY AFTER TKOF AND RETURNS.

Narrative: WE STARTED OUT WITH A FUEL LEAK ON THE #2 ENG. MAINT CAME OUT AND WE RAN THE ENG AT IDLE PWR. THE MECH SIGNED OFF THE LOGBOOK AND WE DEICED THE ACFT; THEN PUSHED 13 MINS LATE. EARLY IN THE TKOF AFTER THRUST WAS SET (MAX PWR DUE TO DEICING) WE SAW A BLEED TRIP LIGHT. I ELECTED TO CONTINUE BECAUSE THRUST WAS SET AND THERE WAS NO OTHER INDICATION OF PROBS. AT ABOUT 2000-3000 FT; WE HEARD A SERIES OF POPS/BANGS FROM THE L SIDE OF THE ACFT. ENG INDICATIONS WERE ERRATIC SO I RETARDED THE #1 THRUST LEVER UNTIL IT APPEARED TO STABILIZE. THE FLT ATTENDANT RANG THE COCKPIT AND WE DID NOT ANSWER IMMEDIATELY BECAUSE WE WERE A LITTLE BUSY RIGHT THEN. WHEN WE ANSWERED THE FLT ATTENDANT CALL; SHE TOLD US THE L ENG WAS ON FIRE. WE CHKED THE FIRE WARNING SYS AND IT TESTED GOOD. I DECIDED TO SHUT DOWN THE ENG AND BLOW THE FIRE BOTTLE BASED ON THE RPTED FIRE. WE PROCEEDED TO INTXN FOR ONE TURN IN HOLDING TO RUN CHKLISTS; CHK PERFORMANCE AND TALK TO DISPATCH. PERFORMANCE WAS GOOD FOR A FLAPS 15 DEG LNDG AT ZZZ (117000 LBS) SO WE DECIDED TO RETURN RATHER THAN GO TO A LONGER AT ZZZ2. WE TOLD THE FLT ATTENDANTS TO SECURE THE CABIN FOR A NORMAL LNDG; THEN MADE A PA TO INFORM THE CUSTOMERS. WE DID AN UNEVENTFUL FLAPS 15 DEG LNDG THAT WAS; I MIGHT ADD; QUITE IMPRESSIVE.
