You mean you let it sit at idle for 15 minutes? If you do this regularly (ie let it warm up just by idling) then you will damage the engine.
It smells like its burning because at low (idle) speeds the engine runs rich (high fuel/low air mixture) whereas normal driving within the rev range it runs lean (high air/low fuel mixture).
The engine is struggling to draw air through so the cars' management systems are revving it to 3000rpm to prevent it stalling. If you drive the car normally (from cold) then it will not do this.
