oxygen content of flue gas in the boiler

When using flue gas from a main or auxiliary boiler an oxygen level of less than 5% can generally be obtained depending on the quality of combustion control and the load on the boiler. When an independent IG generator or a turbine plant with afterburner is fitted the can be automatically controlled within finer limits

Combustion Efficiency and Excess Air

A boilers excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy.

01/05/2017 · During the running of utility boiler, the flue gas oxygen content is one of the most important factors that affects boiler efficiency, and it affects each other with other thermal economic parameters such as flue gas temperature, unburned carbon in fly ash and slag and coal consumption of power supply. So it's a key parameter to optimize the combustion process of fuel in utility boiler through combustion control system.

Flue gas - Wikipedia

A package boiler operates more efficiently if the oxygen concentration in the flue gas is reduced. On the other hand, insufficient air intake causes incomplete combustion, resulting in increased smoke emission. Optimizing air intake for boiler operation requires continuous measurement of the oxygen concentration in
