Genuine MAPP gas can be used in combination with oxygen for heating, soldering, brazing and even welding because of its high flame temperature of 2925 °C (5300 °F) in oxygen. Although acetylene has a higher flame temperature (3160 °C, 5720 °F), MAPP has the advantage that it requires neither dilution nor special container fillers during ...
The constant volume adiabatic flame temperature is the temperature that results from a complete combustion process that occurs without any work, heat transfer or changes in kinetic or potential energy. Its temperature is higher than in the constant pressure process because no energy is utilized to change the volume of the system (i.e., generate ...
An air-fed torch's maximum adiabatic flame temperature is assumed to be around 2,000 °C (3,600 °F). However, a typical primary flame will only achieve 1,100 °C (2,000 °F) to 1,250 °C (2,250 °F). Oxygen-fed torches can be much hotter at up to 2,550 °C (4,600 °F). [8]
The flame temperature is high, about 2,000 °C for hydrogen gas in air at atmospheric pressure, [11] and up to 2800 °C when pre-mixed in a 2:1 ratio with pure oxygen (oxyhydrogen). Hydrogen is not used for welding steels and other ferrous materials, because it causes hydrogen embrittlement .

The state Forest Service has banned outdoor burning in 30 Western North Carolina counties in the wake of a spate of wildfires that have burned thousands of bone-dry acres.
Burn rate (typically expressed in mm/s or in/s) is the sample length over time at a given pressure and temperature. For solid fuel propellant, the most common method of measuring burn rate is the Crawford Type Strand Burning Rate Bomb System [ 3 ] (also known as the Crawford Burner or Strand Burner), as described in MIL-STD-286C.
