Catalytic cracking flue gas desulfurization and dust removal device
Thread Content
On our end, flue gas desulfurization is in place for catalytic cracking, but denitration is not. Currently, the nitrogen oxide levels are within acceptable limits when the main fan is operating, but they become extremely high when the backup fan is used. I’m not sure what’s going on; could Haiyou help analyze it?
With high host power or short channels, the flow rate is high, the combustion temperature is low, and less nitrogen oxide is produced.
The channels are more or less the same; the bed temperature controlled by the main unit and the backup unit has remained similar, as has the combustion efficiency. The power of the main unit is indeed higher, but each time a backup unit is activated, the processing volume and the pressure on the two devices decrease, which has little impact on burning.
Let’s consider it from the perspective of operating conditions; it is closely related to combustion temperature and oxygen content
