From an efficiency standpoint, the excess O2 means there is more air in the combustion stream than there needs to be. That air also contains moisture, and it all is heated and then lost up the stack. The amount of excess O2 is about directly proportional to the efficiency lost; that is, 3% excess O2 means 3% efficiency …

Combustion Efficiency and Excess Air - Engineering …

2020-3-20 · 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 heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels:

Boiler Combustion | CleanBoiler.org

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. Thus, increased stack losses and reduced boiler efficiency occur.

Understanding Combustion Efficiency and …

The entire system (furnace/boiler, ducting, and piping) must be evaluated to determine the true efficiency of the system. Combustion efficiency is a valuable part of the system evaluation, but it is only one part of the evaluation process and cannot be used as the sole reason or justification for keeping or replacing existing equipment.

improving combustion efficiency by incorporating co

Improving combustion efficiency by incorporating CO

2001-5-18 · By adjusting the combustion air level so that the CO concentration lies just above the minimum level (typically 100 to 200 ppm) the boiler efficiency can be optimised. Even where considerations other than maximum efficiency are paramount, knowledge of the CO concentration can be an important indicator of the combustion conditions in the boiler.
