Process for hot dedusting flue gasses, particularly for a waste incineration unit

摘要

Process for removing dust from combustion fumes by passing the fumes across a filter at high temp. (4) placed on the circulation trajectory of the fumes in a heat recovery unit (3) to filter in the heat fly ash contd. in the fumes. An additional flow (B) of unsticking material is superimposed on the flow of fly ash to be filtered. This additional flow has characteristics which raise the fusion temp. of the ash to form high temp. fusion eutectics. This process applies to an incineration unit for waste contg. a heat recovery unit in two parts, between which the filter is placed, or an energy prodn. unit, in partic. combustion under pressure.
