The utility model discloses a flue gas emission device of a bagasse biomass fuel boiler using dry dust removal. The flue gas emission device comprises a dry dust remover and an induced draft fan, theinduced draft fan is distributed behind the dry dust collector; the bagasse biomass fuel boiler is further provided with a fire grate and a boiler barrel, the fire grate is provided with an air inlet,and a cold water preheater and/or a heat energy converter are/is further distributed behind the dry dust remover. A water outlet of the cold water preheater is communicated with a water inlet of theboiler barrel; and an air outlet of the heat energy converter is communicated with an air inlet of the fire grate. According to the utility model, boiler heat energy loss can be reduced, bagasse boiler efficiency is improved, and blockage rate of an exhaust pipeline is reduced. 本实用新型公开了使用干法除尘的蔗渣生物质燃料锅炉的烟气排放装置，包括干法除尘器、引风机；所述引风机分布在所述干法除尘器的后方；所述蔗渣生物质燃料锅炉还设有炉排、锅筒，所述炉排设有空气入口，所述干法除尘器的后方还分布有冷水预加热器和/或热能转换器；所述冷水预加热器的出水口与所述锅筒的进水口连通；所
