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 ...
MAPP gas can be used at much higher pressures than acetylene, sometimes up to 40 or 50 psi in high-volume oxy-fuel cutting torches which can cut up to 12-inch-thick (300 mm) steel. Other welding gases that develop comparable temperatures need special procedures for safe shipping and handling.
A propane torch is a tool normally used for the application of flame or heat which uses propane, a hydrocarbon gas, for its fuel and ambient air as its combustion medium. Propane is one of a group of by-products of the natural gas and petroleum industries known as liquefied petroleum gas (LPG).
Limits vary with temperature and pressure, but are normally expressed in terms of volume percentage at 25 °C and atmospheric pressure. These limits are relevant both in producing and optimising explosion or combustion, as in an engine, or to preventing it, as in uncontrolled explosions of build-ups of combustible gas or dust.
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.

The justification for using oxy-fuel is to produce a CO 2 rich flue gas ready for sequestration. Oxy-fuel combustion has significant advantages over traditional air-fired plants. Among these are: The mass and volume of the flue gas are reduced by approximately 75%. Because the flue gas volume is reduced, less heat is lost in the flue gas.
The adiabatic flame temperature of a given fuel and oxidizer pair is that at which the gases achieve stable combustion. Oxy–dicyanoacetylene 4,990 °C (9,000 °F) Oxy–acetylene 3,480 °C (6,300 °F) Oxyhydrogen 2,800 °C (5,100 °F) Air–acetylene 2,534 °C (4,600 °F) Blowtorch (air–MAPP gas) 2,200 °C (4,000 °F)
