Generally, during the combustion process the sulfur, which is present in the fossil fuel, reacts to form about 95 to 97% sulfur dioxide (SO2) and the remainder sulfur trioxide (SO3) . SCR technologies may generate an additonal quantity of SO3 through catalytic conversion of SO2 to SO3 even at low temperatures. There are twoGet A Quote
When fossil fuels are burned, about 95 percent or more of the sulfur is generally converted to sulfur dioxide ( SO. 2 ). Such conversion happens under normal conditions of temperature and of oxygen present in the flue gas. However, there are circumstances under which such reaction may not occur. SO.Get A Quote
Emissions of SO2 from natural gas-fired boilers are low because pipeline quality natural gas typically has sulfur levels of 2,000 grains per million cubic feet. However, sulfur-containing odorants are added to natural gas for detecting leaks, leading to small amounts of SO2 emissions. Boilers combusting unprocessed natural gas may have higher SO2 emissions due to higher levels of sulfur in the natural gas.Get A Quote
Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the …Get A Quote
