Narrative:

Denver TRACON is now using procedures to radar vector arriving aircraft to bfree or south of it to intercept final for 34R when triple ILS approaches are in use. We had a 30 mile turn to final at 170 kias. This caused us to have extended time in icing conditions; added fuel burn of 1000-1400 lbs and we had a TCAS traffic from centennial 700 feet below us and climbing which might have produced a RA event had we not turned base leg. Having talked to a TRACON supervisor I was told it is the procedure to have 34R aircraft at 10;000 feet turn onto final this far south. At the time it was VFR and we saw the runway [around] 24 miles. We had 6 miles of separation with the [traffic] in front of us and he cleared the runway when we were at 1000 AGL. I feel all 3 of these issues are a safety concern.
