The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1,950 °C (2,220 K; 3,540 °F). [citation needed] This is mostly because the heat of combustion of these compounds is roughly proportional to the amount of oxygen consumed, which proportionally increases the amount of air that has ...
Dicyanoacetylene, a compound of carbon and nitrogen with chemical formula C 4 N 2 burns in oxygen with a bright blue-white flame at a temperature of 5,260 K (4,990 °C; 9,010 °F), and at up to 6,000 K (5,730 °C; 10,340 °F) in ozone. [10]
The blue fire is ignited sulfuric gas, which emerges from cracks at temperatures up to 600 °C (1,112 °F). The flames can be up to five meters (16 feet) high; some of the gas condenses to liquid and is still ignited. [9] [10] Ijen is the largest blue flame area in the world. Local people refer to it as Api Biru (Blue Fire). [11]
"Blue lava" is an electric-blue fire that burns when sulfur combusts, producing a neon-blue flame. Sulfur burns when it comes into contact with hot air at temperatures above 360 °C (680 °F), which produces the energetic flames. [2] Actual lava is red-orange in color, given its temperature.
The yellow flame is considered "dirty" because it leaves a layer of carbon on whatever it is heating. When the burner is regulated to produce a hot, blue flame, it can be nearly invisible against some backgrounds. The hottest part of the flame is the tip of the inner flame, while the coolest is the whole inner flame.
Colored fire. A campfire burning with blue and green flame colorants. Different colors of natural flame from a bunsen burner, without additives. Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and ...
Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.
The maximum neutral flame temperature of propane in oxygen is 2,822 °C (5,112 °F). ... The two parts of this flame are the light blue inner cone and the darker blue ...
