How is the main fan of the sulfur recovery unit controlled?

Here, we manually control the inlet valve and outlet pressure!
How is the exhaust at the fan outlet controlled? When operations experience fluctuations, can manual control keep up?
The exhaust at the fan outlet is also under manual control; adjustments are made on a small scale depending on the inlet pressure. Because the control here is relatively stable; even in the event of an accident, manual adjustment can still meet the requirements!
Our sulfur production fans are controlled by adjusting the frequency conversion. Under normal circumstances, when the opening degree of the fan inlet reaches a certain level and frequency conversion adjustment can no longer meet the production requirements, the inlet is manually opened to an appropriate extent. The relief valve is usually closed; however, when the processing load is low, it is opened to a certain degree to prevent fan surging and ensure its proper operation.
Only the venting is manually controlled, while both the coarse and fine adjustments of air distribution are controlled by the central control system.
If the fan is equipped with an outlet pressure regulator, it is recommended to set the regulator to automatic mode, as this will help maintain a stable outlet pressure for the fan
Is your relief valve controlled manually or automatically? What signal is used for automatic control?
The air conditioning throttle is manually controlled.
