ABSTRACT:
A filtering method of flue gas of a boiler employing a filter apparatus integrated with ceramic filters and provided with a control mechanism for regenerating the ceramic filter by reverse cleaning and a detecting mechanism for detecting directly or indirectly unburnt component. Valves of a compressed gas are operated by a signal from the control mechanism when flying-over of the unburnt component is detected to thereby start at once frequent reverse cleaning wherein the compressed gas is blown into the cleaned gas spaces and thereafter the frequent reverse cleaning having a period shorter than four minutes continues until the flying-over of the unburnt component decreases to a small quantity.
