Fuel Vaporization 1947 Chemistry of Fire US War Department

Vapors in the process of combustion are the gaseous substance given off by the material that is burning. In burning wood, heat causes the resinous substance in the wood to vaporize. The vapors combine with the oxygen of the air, and the flame from the kindling ignites the combustible vapor-oxygen gas.

This is clipped from the 1947 film The Chemistry of Fire from the US War Department. The film describes chemical processes occurring during combustion, using many interesting demonstrations: describes the vaporization of burning articles, demonstrates flash and fire points of various substances, describes how phosphorus burns, oxygen requirements for burning, the operation of an oxy-acetylene torch, and the perils of gasoline vapor, explains ignition temperatures, shows fires caused by static electricity, combustion, bomb explosions, shrapnel piercing fuel lines, and ignition of paint and bedding, describes the use of carbon dioxide, steam, and foam to extinguish fires, fires are extinguished by high-pressure streams of water, by immersion in water, and by flooding. The entire 45 minutes film is available at the US National Archives in College Park, Maryland
