Abstract In this work, by a de-NO_x and dust removal device, the effects of ammonia on temperature of dust deposition, water content of dust, and properties of flue gas dust were investigated. The results showed that, with the increase of the concentration of ammonia, the temperature of dust deposition increased obviously, at the same time, the water content of dust increased too, the average water content in the dust is in the range of 7%~8%. Based on results of SEM and granularity distribution, when the concentration of ammonia reached 710 mg·Nm^-3 in flue gas, the boron oxide ammonia hydrate was found in the dust, particle accumulation occurred, and average size of particle increased, which was helpful for the removal of dusts.
