Ratio with Cross-Limiting Override Control of a …

In its most simple form, the air flow SP is the greater of the boiler master and the actual fuel flow PV (%) and the fuel flow SP is the lesser of the boiler master and the actual air flow PV (%, after it is run through the FAR PWC and O 2-trimmed). This forces air to lead on firing rate increases, and fuel to lead on decreases, and ensures that if the system ever runs out of air, it will never add too much fuel.
