PCT No. PCT/FR96/00984 Sec. 371 Date Jun. 26, 1997 Sec. 102(e) Date Jun. 26, 1997 PCT Filed Jun. 24, 1996 PCT Pub. No. WO97/02453 PCT Pub. Date Jan. 23, 1997The method consists in causing the flue gases to pass through a filter placed inside the recovery boiler so that the fly ash contained in said flue gases can be hot filtered out. An additional flow (B) of a material is superposed on the flow of fly ash to be filtered, which material has characteristics such that it increases the melting point of the fly ash by forming high melting point eutectics so as to facilitate unclogging by preventing viscous bridges from forming between the particles of fly ash. Application to hot scrubbing of flue gases generated by burning household refuse.
