How Do Burner Combustion Control Systems Work? - CrossCo
So we want to control O 2 at its ideal amount for the load. The burner manufacturer should provide an O 2 trim SP curve – this should be plugged into a PWC with the output running through a bias station (always in auto!) to set the SP of the O 2 trim PID loop. Operators should NOT have the option to set the O2 Trim SP – they can put the ...
