what is the temperature of a propane torch
Propane torch Oxygen-fed torches use the high pressure of the stored oxygen to push the oxygen into a common tube with the fuel. An air-only torch will burn at around 1,995 °C (3,623 °F), less if heat loss to the surroundings is taken into account. Oxygen-fed torches can be much hotter at up to 2,820 °C (5,110 °F), depending on the fuel-oxygen ratio. These are the theoretical maximum temperatures, in reality they will always be less due to incomplete combustion, heat loss etc.
Bunsen burner The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture of both.
Corona Spectroscopy measurements indicate strong ionization and plasma temperature in excess of 1,000,000 kelvins,[1] much hotter than the surface of the Sun.
Temperature coefficient Temperature coefficients are specified for various applications, including electric and magnetic properties of materials as well as reactivity. The temperature coefficient of most of the reactions lies between - 2 & 3
