Common Boiler Excess Air Trends and Strategies to Optimize

the stoichiometric air/fuel ratio, AFs. For natural gas, AFs is about 17.2 lbm-air/lbm-ng. The quantity of air supplied in excess of stoichiometric air is called excess air, EA. Excess air can be written in terms of the stoichiometric air/fuel ratio, the combustion air mass flow rate, ma, and fuel mass flow rate, mf.

1.4 Natural Gas Combustion - US EPA

Natural gas is considered to be one of the cleanest of the commonly used fossil fuels. The emissions from natural gas-fired boilers and furnaces include nitrogen oxides (NOx), carbon monoxide (CO), and carbon dioxide (CO2), and trace amounts of sulfur dioxide (SO2), particulate matter (PM), organic compounds, and other greenhouse gases.

Why is atomization with steam done in oil-fired boilers

Answer (1 of 2): Fuel is atomized so that it will readily mix with the air and burn fully and quickly. If you shot a solid stream of fuel into a boiler, it would take a long time for all that fuel to burn completely, if you could get it to do so. If the fuel doesn't atomize properly, it won't hav

Natural Gas Fired Boilers - innovativecombustion.com

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and
