air fuel ratio effect on combustion efficien

Air Fuel Ratio Effect on Combustion Efficien

Oct 23, 2013· In the combustion zone, it is challenging to measure excess air. In the stack, however, it can be easily measured using Oxygen analyzers. When operating with 5%-20% excess air, it would correspond to a 1% to 3% oxygen measurement in the stack. The ideal air-to-fuel relationship will vary at different operating loads.

Combustion Efficiency and Excess A

To ensure complete combustion of the fuel used combustion chambers are supplied with excess air. Excess air increase the amount of oxygen to the combustion and the combustion of fuel. when fuel and oxygen from the air are in perfect balance - the combustion is said to be stoichiometric. The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the …

If some carbon molecules cannot find some oxygen molecules, they will partially convert to CO (carbon monoxide) rather than CO2 (carbon dioxide). All burner/boilers are designed to have some “excess air” to reduce the amount of CO made. Why it’s controlled: In its gaseous form, CO is a poisonous substance. In solid form it is commonly referred to as soot, an unhealthy and dirty substance.

Wood fired boilers are significant air pollution emission sources in the region whose emissions can be exacerbated by lack of proper operation and maintenance. New wood boilers greater than 90 bhp are required to equip the boiler with an emission control device such as an electrostatic precipitator or a fabric filter to achieve an emission limit of 0.03 lbs/MMBtu of filterable particulate matter.
