2020-2-10 · To prevent this, burner CCSs implement cross-limiting. 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
