Effect of fine ash particles on formation mechanism o

A part of fine ash particles tend to deposit on the heating surface and plenty of the relatively larger particles are flowing downward with flue gas. Thus, a part of acid condensation in fly ash particles is flowing away with flue gas and the other part around fine ash particles is sticking to the heating surface.
