The air/fuel ratio is also configured so that on increasing loads the combustion air flow leads the fuel flow and conversely on decreasing loads the fuel leads the air. Many Ultra-Low NOx burners will require what is described as a "double cross-limited" system, which requires a very tight control of the air/fuel ratio during load swings.
