Boiler Combustion | CleanBoiler.org

As a safety factor to assure complete combustion, boilers are fired with excess air. One of the factors influencing NOx formation in a boiler is the excess air levels. High excess air levels (>45%) may result in increased NOx formation because the excess nitrogen and oxygen in the combustion air entering the flame will combine to form thermal NOx.

Boiler Operations That Affect Efficiency (Part 1)

Boiler Operations That Affect Efficiency. In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production). However, these two goals often have opposing outcomes.

Burner Combustion Control for Boilers | Eurotherm by Schneider Electric

Burner modulation. Modulating control is a basic improvement in controlling combustion. A continuous control signal is generated by a controller monitoring the steam or hot water line. Reductions in steam pressure or hot water temperature lead to an increase in firing rate. The advantages of introducing burner modulation in combustion control

Improving Boiler Efficiency - Energy Depot

Reduce Excess Air. Efficiency Improvement - Up to 5 percentage points. Properly operated boilers require a certain amount (10% to 20%) of excess air to ensure complete combustion. However, operating with too much excess air reduces boiler efficiency by heating up and throwing away this "cushion" of excess air.
