Calculation of the Excess Air of Combustion Process

Apr 16, 2018 · Calculation of the Excess Air of Combustion Process. Generally, coal fired boilers use excess air as much as 15% to 30%. For boilers with gas or petroleum as its fuel, requires less excess amount of water. Gas-fired boilers require excess air of 5% to 10%, while petroleum-fired boilers require excess air of 3% to 15%.

Industrial Combustion Boilers - IEA-ETSAP

water-tube boilers, tubes containing water are heated by combustion gases that flow outside the tubes, while in the fire-tube boilers hot combustion gases flow inside the tubes and water flows outside. Key design parameters to determine the boiler size and power are the output steam mass flow rate, pressure and temperature.

Performing a Combustion Analysis - ACHR News

Mar 03, 2008 · As a safety factor, to ensure complete combustion, appliances are fired with excess air. One of the factors influencing NOx formation in a furnace or boiler is excess air. High excess air levels (>45 percent) 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.

Combustion Process Analysis and Diagnostic Using Optical

The combustion process analysis and diagnostic has a crucial influence on boiler effectiveness, especially in high variance of load demand, which is nowadays a top challenge for coal-fired power plants. The first indicator of combustion inefficiency is flame stability, which can be observed as variation of flame intensity.

1.3 Fuel Oil Combustion

Two major categories of fuel oil are burned by combustion sources: distillate oils and residual oils. These oils are further distinguished by grade numbers, with Nos. 1 and 2 being distillate oils; Nos. 5 and 6 being residual oils; and No. 4 being either distillate oil or a mixture of distillate and residual oils.

Calculation of the Excess Air of Combustion Process

Apr 16, 2018 · Therefore, when the boiler is below full load, the amount of excess air required increases to ensure a complete combustion. In coal-fired boilers for example, at 50% load, takes two times excess air than when the load is 100%. Although the excess air is important to ensure complete combustion, excess air has a negative impact on boiler efficiency.
