B737-300 CREW RPTS AFTER THOROUGH ACFT AND ENG DEICING THE ENGS WERE NOT DAMAGED AT DEST.

Narrative

WE FLEW FROM DEN TO DSM. I (FO) PERFORMED THE WALKAROUND INSPECTION; DURING WHICH I REALIZED THE ACFT WOULD HAVE TO BE DEICED DUE TO A BUILDUP OF RIME ICE ON THE LNDG GEAR FROM INFLT ICING. A DEICING CREW INFORMED ME THEY WOULD BE DEICING THE LNDG GEAR AND ENGS AT THE GATE. I COMPLETED MY WALKAROUND INSPECTION; NOTING THAT THE DEICE CREW HAD DEICED BOTH ENGS AND THAT BOTH FANS TURNED FREELY. WE STARTED BOTH ENGS; TAXIED FROM THE GATE ON TXWY; TO AWAIT OUR TURN IN THE DEICE PAD. WE DEICED IN THE PAD; DURING WHICH WE SHUT DOWN #1 ENG; RAN THE APU FOR THE L PACK; AND RAN THE #2 ENG FOR THE R PACK (MY ESTIMATION ON ELAPSED TIME FROM THE GATE TO COMPLETION OF DEICING IS APPROX 12 MINS). WE STARTED THE #1 ENG; I COMPLETED A WING INSPECTION; AND WE TAXIED FOR TKOF ON RWY 34. APPROX 4 MINS ELAPSED FROM TAXIING FROM THE DEICE PAD TO TKOF ON RWY 34. WE ACCOMPLISHED ALL COLD WX OPS (ENG HEAT; IGNITERS; TKOF RUNUP) AS PER THE FLT MANUAL. WE DID NOT NOTICE ANY ABNORMAL INDICATIONS IN EITHER ENG DURING ANY OF THE DENVER GND OPS; TKOF RUNUP; TKOF; DEP; ENRTE; OR ARR PHASES INTO DSM.
