Why analyze the oxygen content at the inlet and outlet of the flue gas desulfurization tower
Thread Content
Dear teachers: In the flue gas desulfurization and dust removal system, why is it necessary to analyze the oxygen content at the inlet and outlet of the flue gas desulfurization tower, and what are the appropriate values for these indicators? Thank you! ! !
We don’t have much control over it, but it can help analyze the oxygen content in the regenerative system; sometimes the oxygen level in that system may be inaccurate, which in turn affects the main air flow rate
The oxygen content at the flue gas desulfurization inlet is generally not controlled, but the oxygen content at the flue gas inlet also cannot fully reflect the amount of main air used in the regeneration process. This is because there is a significant amount of air used for backblowing purposes from the regenerator to the boiler’s control systems, in addition to the air supplied to the boiler itself; it is therefore very difficult to determine the main air volume based on this parameter alone
The import content indicates whether the boiler is burning completely. For complete combustion, the oxygen content is 6%, with a standard of 9% as well. As for controlling the oxygen content, the main purpose is to convert the dust content at the outlet of the desulfurization tower.
Thank you! ! ! Dear teachers! ! ! !
