Spraying ammonia into desulfurization flue gas has no effect.

1, the atomization effect of ammonia water has a great correlation with desulfurization efficiency. The better the atomization effect, the larger the contact area between ammonia water and flue gas, and the higher the removal efficiency of sulfur dioxide, which will lead to the ineffective spraying of ammonia water on desulfurization flue gas.

2. Ammonia desulfurization technology generally has some shortcomings, such as high consumption of desulfurizer, serious ammonia escape, difficult elimination of aerosol and slow oxidation of ammonium sulfite, which will lead to the ineffectiveness of injecting ammonia water into desulfurization flue gas.
