What should be noted when operating the ammonia-based desulfurization system?
The problem of sulfate AN clogging the pipelines.
For ammonia-based desulfurization, pay attention first to the temperature inside your desulfurization tower – it should not exceed the decomposition temperature of sulfurous acid； Secondly, pay attention to the water balance issue ； We previously used the ammonia-based desulfurization method, but its operation was unstable; later we switched to the alkali-based desulfurization method, and now the operation is stable. The levels of sulfur dioxide and dust are both below 10, while nitrogen oxides are below 50 ；
Corrosion, ammonia escape, unstable emissions,
The unstable emissions – what causes that? Is it because the amount of ammonia added cannot be controlled properly?
Regularly flushing the pipelines should not be a problem, right?
Where is the blockage mainly concentrated?
As long as there are fluctuations in the sulfur production furnace and the exhaust gas furnace, the parameters will exceed the specified limits; more importantly, changes in the components of the acidic gases can also cause these parameters to exceed the limits
