Hot heat exchanger surfaces can be covered with tar or coke deposits that are in fact products of a chemical reaction. This chemical reaction occurs near the hot surface and produces solid particles or very viscous tar that accumulate on the surface.
So rather than having a smooth and potentially slick surface like asphalt, the surface of tar and chip driveways is rough.
