Air Fuel Ratio Effect on Combustion Efficiency - Sage Metering
Air-to-fuel ratio defines the amount of air needed to burn a specific fuel. The conventional fuels used in a combustion process are: oil (#2, 4 and 6), diesel oil, gasoline, natural gas, propane, and wood.
Optimal Combustion Process - Fuels and Excess Air
Even so-called "on-ratio" combustion, used in boilers and high temperature process furnaces incorporates a modest amount of excess air - 10 to 20% more than needed to burn the fuel completely. If insufficient amount of air is supplied to the burner, unburned fuel, soot, smoke, and carbon monoxide are exhausted from the boiler.

Air–fuel ratio - Wikipedia
Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion, gas or vapour explosion or in a thermobaric weapon).

up to four actuators to maintain optimum fuel/combustion air ratio and ßue gas recirculation (if so equipped) on a boiler/ burner package. A. Major Components 1. Fuel Air Ratio Controller (P/N 833-2801) Controls the relationship between fuel, air ßow and ßue gas recirculation (FGR), if used. The controller (see Figure 1-1) is
How to Calculate the Stoichiometric Air-fuel Ratio
The stoichiometric air-fuel ratio is an important parameter of fuels. When designing an engine for a particular fuel, it's important to know how much air is needed to completely burn a certain amount of fuel. This article describes this ratio and presents an easy way to calculate it when the composition of a fuel is known.

Best Practices for Combustion Efficiency/Fuel Air Ratio
The fuel/air ratio curve is the lowest excess air level (measure in percent of oxygen 0 2 ) in the flue gas; at a set firing rate without the carbon monoxide (C0) being produced.
Boiler control - Plant Services
Continuously matching fuel and air rates to demand. Closer steam pressure or water temperature tolerances. Improving boiler efficiency. Reducing the weighted average flue-gas temperature. Air/fuel cross-limiting. A cross-limiting combustion-control strategy ensures there can never be a dangerous air/fuel ratio in the system.
