Three mornings ago I noticed that the flames on my gas stove burners were different. They used to be all blue; it became small blue tongues with large orange-ish flame above. I lit the oven, and ditto. That evening, when the boiler fired up, I examined its flame color and it also had changed. What used to be nice blue tongues, with larger blue flames above and occasional whisps of yellow, had become small blue tongues with long dirty orange-color flame above. Adjustment of the air control made no significant change.
Is this "dirty gas"? I've never seen anything like this.
