Abstract: The influences of the fly ash particle size and the concentration of dry/semidry desulphurized dust on the deashing mode of the bag filter for garbage incinerator were introduced, and the design details of the nozzle and the tubesheet were described. The method for selecting the filter materials in accordance with the flue gas characteristics of the garbage incinerator was expounded. By taking an engineering project as an example, the importance of design and type selection of bag filter for garbage incinerator on the basis of the flue gas characteristics were illustrated.

Key words: garbage incinerator, dedusting, bag filter, tubesheet, filter bag
