Flue gas desulfurization issue: How to put the SCR ammonia injection system into operation at startup

As the title suggests, could the experts explain this in detail?
Does the expert have an attachment? Could you send it to me?

A brief description: When the temperature of the catalyst bed reaches the specified value, the dilution fan is started to inject ammonia; the amount of ammonia injected is adjusted by measuring the nitrogen oxide levels in the exhaust gas and the ammonia escape rate, so as to ensure that the emission levels meet the required standards. (It would be even simpler if there are automatic control systems for the chimney emission standards and the ammonia injection system.)
