Firing Rate vs Boiler Load - Energy engineering

Can anyone explain or is there a graph on how firing rate relates to boiler load? I'm wondering on how does combustion efficiency relates to boiler efficiency. On my perspective, a boiler with a burner turndown of 4:1 (25% lowest firing rate) will have 4 different efficiencies ( to 25%) but it does not take into account the boiler load.

Steam Calculators: Boiler Calculator

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Air-fuel ratio, lambda and engine performance – x

How stoichiometric air-fuel ratio is calculated. In order to understand how the stoichiometric air-fuel ratio is calculated, we need to look at the combustion process of the fuel. Combustion is basically a chemical reaction (called oxidation) in which a fuel is mixed with oxigen and produces carbon dioxide (CO 2), water (H 2 O) and energy (heat). Take into account that, in order for the
