Abstract
The 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.
