  2. Phantosmia - Wikipedia

    en.wikipedia.org/wiki/Phantosmia

    Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, [1] is smelling an odor that is not actually there. This hallucination is intrinsically suspicious as the formal evaluation and detection of relatively low levels of odour particles is itself a very tricky task in air epistemology.

  3. Metal fume fever - Wikipedia

    en.wikipedia.org/wiki/Metal_fume_fever

    Metal fume fever, also known as brass founders' ague, brass shakes, [1] zinc shakes, galvie flu, galvo poisoning, metal dust fever, welding shivers, or Monday morning fever, [2] is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al 2 O 3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are ...

  4. Combustion - Wikipedia

    en.wikipedia.org/wiki/Combustion

    The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

  5. High-temperature corrosion - Wikipedia

    en.wikipedia.org/wiki/High-temperature_corrosion

    High-temperature corrosion is a mechanism of corrosion that takes place when gas turbines, diesel engines, furnaces or other machinery come in contact with hot gas containing certain contaminants. Fuel sometimes contains vanadium compounds or sulfates, which can form low melting point compounds during combustion.

  6. Thermite - Wikipedia

    en.wikipedia.org/wiki/Thermite

    Use of match heads enveloped with aluminum foil and a sufficiently long viscofuse/electric match leading to the match heads is possible. [ citation needed ] Similarly, finely powdered thermite can be ignited by a flint spark lighter , as the sparks are burning metal (in this case, the highly reactive rare-earth metals lanthanum and cerium ). [ 37 ]

  7. Sulfur dioxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_dioxide

    Sulfur dioxide is the product of the burning of sulfur or of burning materials that contain sulfur: S 8 + 8 O 2 → 8 SO 2 , ΔH = −297 kJ/mol To aid combustion, liquified sulfur (140–150 °C (284–302 °F) is sprayed through an atomizing nozzle to generate fine drops of sulfur with a large surface area.

  8. History of manufactured fuel gases - Wikipedia

    en.wikipedia.org/wiki/History_of_manufactured...

    The gas would smell of rotten eggs when burnt; The gas-works and adjacent district would smell of rotten eggs when the gas-works was producing gas; The gas, upon burning, would form sulfur dioxide, which would be quickly oxidized to sulfur trioxide, and subsequently would react with the water vapor produced by combustion to form sulfuric acid ...

  9. Polymer fume fever - Wikipedia

    Symptoms are flu-like (chills, headaches and fevers) with chest tightness and mild cough. Onset occurs about 4 to 8 hours after exposure to the pyrolysis products of PTFE. [ 3 ] A high white blood cell count may be seen and chest x-ray findings are usually minimal.
