  2. Boiler explosion - Wikipedia

    en.wikipedia.org/wiki/Boiler_explosion

    Oil fumes, natural gas, propane, coal, or any other fuel can build up inside the combustion chamber. This is especially of concern when the vessel is hot; the fuels will rapidly volatilize due to the temperature. Once the lower explosive limit (LEL) is reached, any source of ignition will cause an explosion of the vapors.

  3. Flame lift-off - Wikipedia

    en.wikipedia.org/wiki/Flame_lift-off

    Flame lift-off in oil fired pressure jet burners is an unwanted condition in which the flame and burner become separated. This condition is most commonly created by excessive combustion air and often results in the loss of flame as the photoelectric cell fails to register the light of the flame, this in turn results in a safety lockout of the control box.

  4. Combustion instability - Wikipedia

    en.wikipedia.org/wiki/Combustion_instability

    Such a pulsating stream may well be produced by acoustic oscillations in the combustion chamber that are coupled with the fuel-feed system. Many other causes are possible. The fuel mixes with the ambient air in a way that an inhomogeneous mixture reaches the flame, e.g., the blobs of fuel-and-air that reach the flame could alternate between ...

  5. Diesel engine runaway - Wikipedia

    en.wikipedia.org/wiki/Diesel_engine_runaway

    Fuel and oil leaks causing engine runaways can have both internal and external causes. Broken seals or a broken turbocharger may cause large amounts of oil mist to enter the inlet manifold, whereas defective injection pumps may cause an unintentionally large amount of fuel to be injected directly into the combustion chamber.

  6. Combustion chamber - Wikipedia

    en.wikipedia.org/wiki/Combustion_chamber

    Considering the definition of combustion chamber used for internal combustion engines, the equivalent part of a steam engine would be the firebox, since this is where the fuel is burned. [citation needed] However, in the context of a steam engine, the term "combustion chamber" has also been used for a specific area between the firebox and the ...

  7. Adiabatic flame temperature - Wikipedia

    en.wikipedia.org/wiki/Adiabatic_flame_temperature

    Because most combustion processes that happen naturally occur in the open air, there is nothing that confines the gas to a particular volume like the cylinder in an engine. As a result, these substances will burn at a constant pressure, which allows the gas to expand during the process.

  8. Boiler - Wikipedia

    en.wikipedia.org/wiki/Boiler

    In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas.In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used.

  9. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    65–97% for gas-fired heating; 80–89% for oil-fired and; 45–60% for coal-fired heating. [26] Oil storage tanks, especially underground storage tanks, can also impact the environment. Even if a building's heating system was converted from oil long ago, oil may still be impacting the environment by contaminating soil and groundwater.
