The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. [1] The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). [2] A fire naturally occurs when the elements are present and combined in the right mixture. [3]
Dragon's breath (sustained vertical breath without a torch in front of the flame) Fire art is a piece of art that uses active flames as an essential part of the piece. The piece may either use flame effects as part of a sculpture, or be a choreographed performance of fire effects as the piece burns; the latter being almost a type of performance art.
A fire is contained in a firebox or fire pit; a chimney or other flue allows exhaust gas to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantel , a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel , a lintel bar, an overmantel , a damper , a smoke chamber, a throat, a flue, and a ...
The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. [2] Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. [3]
A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic chemical reaction made in a thin zone. [ 1 ] When flames are hot enough to have ionized gaseous components of sufficient density, they are then considered plasma .
Flammability diagram for methane. Flammability diagrams show the control of flammability in mixtures of fuel, oxygen and an inert gas, typically nitrogen.Mixtures of the three gasses are usually depicted in a triangular diagram, known as a ternary plot.
Flame coloring is also a good way to demonstrate how fire changes when subjected to heat and how they also change the matter around them. [1] [2] To color their flames, pyrotechnicians will generally use metal salts. Specific combinations of fuels and co-solvents are required in order to dissolve the necessary chemicals.
There are four elements [38] needed to start and sustain a fire and/or flame: temperature, a fuel, an oxidizing agent (oxygen), and a chemical reaction. A fire can be extinguished by taking away any of the four components. [38] The fuel is the substance being oxidized or burned in the combustion process.
