This is when the glowing and smoldering (as opposed to flaming) phases initiate, producing more fuel gases and also char: a black carbon coat representing incomplete combustion. The all-important reaction zone-where oxygen and fuel gases engage with one another and split their chemical bonds-must eventually collapse to the solid fuel in order to keep the combustion going. As flaming combustion proceeds through the explosive, energy-releasing reaction of oxygen and fuel gases, enough heat is generated to convert the fire into a self-perpetuating one. This creates a waft of flammable gases above the fuel that the pilot heat can then set alight in the ignition stage. In combustionвЂ™s pre-ignition stage, a heat source (вЂњpilot heatвЂќ) ramps up the temperature to dry out the fuel, boiling away its moisture, and volatizing oils, resins, and other compounds. All three-in proper proportions, too-are required to set those flames happily dancing, and managing them is your M.O.

Perhaps you know the three fundamentals of combustion composing the вЂњfire triangleвЂќ: fuel, heat, and oxygen. The Fire Triangle, and Other Combustion Basics But your fire-building props can only be enhanced with a bit of knowledge of the science behind coaxing flame out of wood-not to mention some insider tips on fire-building in inclement conditions, cooking over fire, and being a responsible fire-maker. ItвЂ™s absolutely possible to achieve such skill level without ever learning about the chemistry of combustion. (Take that too far, though, and youвЂ™ve got one of those arenas prone to obnoxious contests and condescending tutorials by insecure campers compelled to demonstrate their outdoorsy and macho bona fides.) Really, thereвЂ™s no one formula that translates to the вЂњbestвЂќ campfire: There are certainly various options for fuel arrangement and materials, as long as you understand the basic principles of combustion.ДЇor some lucky souls, efficient fire-kindling is intuitive, their method honed through a lot of practice (or maybe some innate talent inherited from thousands of generations of fire-making ancestors). Building the perfect campfire: an indispensable skill for any outdoors enthusiast, given the life-saving properties of an emergency blaze-not to mention the fundamental bragging rights.
