Combustion ( /kəmˈbʌs.tʃən/) or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of heat can produce light in the form of either glowing or a flame. Fuels of interest often include organic compounds (especially hydrocarbons) in the gas, liquid or solid phase.

Famous quotes containing the word combustion:

    The night has been unruly. Where we lay,
    Our chimneys were blown down, and, as they say,
    Lamentings heard i’ th’ air, strange screams of death,
    And prophesying with accents terrible
    Of dire combustion and confused events,
    New-hatched to the woeful time.
    William Shakespeare (1564–1616)

    Him the Almighty Power
    Hurld headlong flaming from th’ Ethereal Skie
    With hideous ruine and combustion down
    To bottomless perdition, there to dwell
    In Adamantine Chains and penal Fire,
    Who durst defie th’ Omnipotent to Arms.
    Nine times the Space that measures Day and Night
    To mortal men, he with his horrid crew
    Lay vanquisht, rowling in the fiery Gulfe
    John Milton (1608–1674)
