Oct 30, 2019 · This boiler design results in a fast mix of air and fuel and encourages rapid heat transfer. The burning environment gives a cleaner burn with reduced quantities of NOx and SO2 in the flue gases. SO2 emissions can be reduced further by introducing pulverized limestone into the combustion chamber.Get A Quote
CO2, CH4, and N2O emissions are all produced during natural gas combustion. In properly tuned boilers, nearly all of the fuel carbon (99.9 percent) in natural gas is converted to CO2 during the combustion process. This conversion is relatively independent of boiler or combustor type. Fuel carbonGet A Quote
In addition to SO2 and CO2, other variables were also mea-sured for reference, such as stack temperature, NO*, O2 and fuel consumption rate. Figure 2 is a condensed plot of correlation between SO2 and CO2 measurements from a two-pen recorder output. Typical results of the boiler emission during Sept. 10-22, 1974 were: Cartridge filter SO2 CO2 =Get A Quote
fuel and are not affected by boiler size, burner design, or grade of fuel being fired. On average, more than 95 percent of the fuel sulfur is converted to SO2, about 1 to 5 percent is further oxidized to sulfur trioxide (SO3), and 1 to 3 percent is emitted as sulfate particulate. SO3 readily reacts with water vapor (both in theGet A Quote
In layman's terms, the oxygen in the air and the hydrogen and carbon in the fuel are oxidized (combined) in the combustion process and the result is heat and CO2 (carbon dioxide) and H2O (water vapor). In real-world conditions, two major byproducts are also produced: NOx and CO (carbon monoxide).Get A Quote

The level of SOx emitted depends directly on the sulfur content of the fuel. The level of SOx emissions is not dependent on boiler size or burner design. Typically, about 95% of the sulfur in the fuel will be emitted as SO2, 1-5% as SO3, and 1-3% as sulfate particulate. Sulfate particulate is not considered part of the total SOx emissions.Get A Quote
