Those that do produce acidic oxides. Burning Sulfur Compounds Sulfur compounds such as hydrogen sulfide (H2S), methyl mercaptan (CH4S) and sulfur (S) burn in the presence of oxygen to produce sulfur oxides (SO2 and SO3) in the flue gas. Your teacher will not demonstrate this reaction, because the sulfur dioxide that forms is a poisonous gas that you and your classmates should not be exposed to. Flue gas always (almost) contains substantial water vapor (hydrogen in the combustibles combines with oxygen in the combustion air to form H2O). There is formation of new bonds in products and breakage of older bonds. The technology burns fuel at temperatures of 1,400 to 1,700 °F (760 to 930 °C), well below the threshold where nitrogen oxides form (at approximately 2,500 °F (1,370 °C), the nitrogen and oxygen atoms in the combustion air combine to form nitrogen oxide pollutants); it also avoids the ash melting problems related to high combustion temperature. 29K subscribers Subscribe Burning sulfur is defined as the process of atomizing molten elemental sulfur in a hot furnace and oxidizing the resulting droplets with excess dried air, producing a gas mixture that primarily contains sulfur dioxide, oxygen, and nitrogen, which is essential for subsequent sulfuric acid manufacture.
