A gas burner is a device that produces a controlled flame by mixing a fuel gas such as acetylene, natural gas, or propane with an oxidizer such as ambient air or oxygen provided, and allows for combustion and combustion.
Flame is generally used for heat, infrared radiation, or visible light that it produces. Some burners, such as flare gas, remove flammable or non-combustible gases. Some burners are operated to produce carbon black.
The gas burner has many applications such as soldering, brazing, and welding, the latter using oxygen instead of air to produce a hotter fire, which is needed to melt the steel. Chemical laboratories use Bunsen burner fueled by natural gas. To melt metals with melting points up to 1100 ° C (such as copper, silver, and gold), propane burners with natural air drag can be used. For higher temperatures, acetylene is commonly used in combination with oxygen.

Fixed gas and fuel temperatures
The above data are provided with the following assumptions:
- Adiabatic flames
- The air around it at 20 ° C, 1 bar atm
- Perfect burning (no soot, and more blue flame is the key) (Stoichiometry)
- Peak Temperature
- Burning Speed ​​(no effect on temperature, but more energy released per second (adiabatic) than normal flame)
- The spectrum band also affects the flame color, such as parts and elements of burning
- Black radiation (color appearance only because of heat)
- Atmosphere - affects flame temperatures and colors due to atmospheric color effects
