An improved solids incineration process and system are provided of the type wherein the solids are combusted and the resulting combustion gases are separated from combustion ash, the ash is quenched and neutralized with a quench liquid, heat is removed from the combustion gases and the combustion gases contacted with a scrubber liquid in a wet scrubber to remove fly ash therefrom. By the present invention, the spent scrubber liquid from the wet scrubber is utilized as at least a portion of the ash quench liquid.
