  2. Staged combustion - Wikipedia

    en.wikipedia.org/wiki/Staged_combustion

    The first stage of combustion occurred inside a hot bulb, where the hot gases were forced out into the cylinder. Then, when mixed with additional air, the second stage of combustion took place. During those times, staged combustion was used because it was a convenient method of ignition, and, likely, there was not much concern about air pollution.

    A non-combustible material [17] is a substance that does not ignite, burn, support combustion, or release flammable vapors when subject to fire or heat, in the form in which it is used and under conditions anticipated. Any solid substance complying with either of two sets of passing criteria listed in Section 8 of ASTM E 136 when the substance ...

    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. Air–fuel ratio - Wikipedia

    en.wikipedia.org/wiki/Air–fuel_ratio

    Typically a range of air to fuel ratios exists, outside of which ignition will not occur. These are known as the lower and upper explosive limits. In an internal combustion engine or industrial furnace, the air–fuel ratio is an important measure for anti-pollution and performance-tuning reasons.

  6. Air pollution - Wikipedia

    en.wikipedia.org/wiki/Air_pollution

    Outdoor particulate pollution was the largest cause of death (4.7 million), followed by indoor air pollution (3.1 million) and ozone (0.5 million). [5] A study published in 2019 estimated that, for 2015, the number was around 8.8 million, with 5.5 million of these premature deaths due to air pollution from human sources.

  9. Hot air engine - Wikipedia

    en.wikipedia.org/wiki/Hot_air_engine

    The term "hot air engine" specifically excludes any engine performing a thermodynamic cycle in which the working fluid undergoes a phase transition, such as the Rankine cycle. Also excluded are conventional internal combustion engines , in which heat is added to the working fluid by combustion of fuel within the working cylinder.
