A process and apparatus for removing flue gas cleaning residues in a combustion system. The combustion system includes a combustion chamber; a hot gas filter located downstream from the combustion chamber; and washers located downstream from the hot gas filter which employ a washing liquid. The hot gas filter includes filter elements and an inlet chamber located below the filter elements. Contaminants present in flue gas are precipitated in the washing liquid. Then, the washing liquid is neutralized, thereby enriching the washing liquid with salts. Next, the enriched washing liquid is injected into the inlet chamber, whereby the washing liquid evaporates and the salts contained in the washing liquid are deposited on the filter elements where they can later be removed and mixed with ashes from the combustion chamber.
