Hey Guys,
I work in a waste to energy plant.
Basically we burn waste and recover the heat to produce steam.
We have a flue gas treatment system that uses lime to neutralize the acid in the flue gas.
The flue gas passes through a lime reaction chamber and lime is fed into the chamber to neutralize to acid.
Currently, the controller measures the HCL concentration at the flue gas stack and controls the amount of lime being fed into the chamber.
However, the waste is very random, we don't know the amount of Cl content in the waste. And we do not have a transmitter to measure HCl content before the chamber.
I would like to ask for advice on what method can I use to tune the controller? Currently, the PV is very random, sometimes high and sometimes low.
