Narrative:
I took off with engine anti-ice on after being deiced near the gate. As I lowered the nose to accelerate to flap/slat retract speed; I heard a loud banging several times and looked to the engine instruments where I saw the left engine N2 and EPR gauges 'bumping' to the left with each banging sound. I realized it was compressor stall and retarded the left throttle. Passing 1.4 EPR; the banging stopped and the engine stabilized around 1.3 EPR. I left it at that setting for the remainder of the flight since it was stable and desired to focus on getting the aircraft back onto the ground instead of wandering the skies. I declared an emergency and the tower gave us carte blanche so we stayed in a closed right pattern; landing without further incident. A postflt look at the left engine revealed several damaged blades and scarring or scraping of the inside of the engine case.

Title: AFTER DEICING AT THE GATE; MD80 EXPERIENCES SEVERE COMPRESSOR STALLS AND EVENTUAL DAMAGE TO L ENG INTAKE AND COMPRESSOR BLADES.
Narrative: I TOOK OFF WITH ENG ANTI-ICE ON AFTER BEING DEICED NEAR THE GATE. AS I LOWERED THE NOSE TO ACCELERATE TO FLAP/SLAT RETRACT SPD; I HEARD A LOUD BANGING SEVERAL TIMES AND LOOKED TO THE ENG INSTS WHERE I SAW THE L ENG N2 AND EPR GAUGES 'BUMPING' TO THE L WITH EACH BANGING SOUND. I REALIZED IT WAS COMPRESSOR STALL AND RETARDED THE L THROTTLE. PASSING 1.4 EPR; THE BANGING STOPPED AND THE ENG STABILIZED AROUND 1.3 EPR. I LEFT IT AT THAT SETTING FOR THE REMAINDER OF THE FLT SINCE IT WAS STABLE AND DESIRED TO FOCUS ON GETTING THE ACFT BACK ONTO THE GND INSTEAD OF WANDERING THE SKIES. I DECLARED AN EMER AND THE TWR GAVE US CARTE BLANCHE SO WE STAYED IN A CLOSED R PATTERN; LNDG WITHOUT FURTHER INCIDENT. A POSTFLT LOOK AT THE L ENG REVEALED SEVERAL DAMAGED BLADES AND SCARRING OR SCRAPING OF THE INSIDE OF THE ENG CASE.
