S: (n) deflagration (combustion that propagates through a gas or along the surface of an explosive at a rapid rate driven by the transfer of heat)
S: (n) fire, flame, flaming (the process of combustion of inflammable materials producing heat and light and (often) smoke) "fire was one of our ancestors' first discoveries"

S: (n) combustion, burning (a process in which a substance reacts with oxygen to give heat and light)
S: (n) nitrification (the oxidation of ammonium compounds in dead organic material into nitrates and nitrites by soil bacteria (making nitrogen available to plants))
