The simplest control scheme would set the fuel flow to meet the demand for steam and set the air flow in ratio to the fuel. However, this scheme has a problem when the boiler is operating at the optimum air-to-fuel ratio, which is where the combustion air rate is just sufficient to provide complete combustion.

Steam Boiler Questions and Answers

Combustion Air: Fuel/ Air Ratio Burner air-fuel ratio plays a critical role in achieving maximum efficiency out of fuel-fired process heating systems such as furnaces, ovens, heaters, and boilers. If the amount of air supplied is less than required, the burner will run "rich" i.e. not all fuel will burn inside the furnace.

air fuel ratio in boiler

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).
