Approximately 20% of acetylene is supplied by the industrial gases industry for oxyacetylene gas welding and cutting due to the high temperature of the flame. Combustion of acetylene with oxygen produces a flame of over 3,600 K (3,330 °C; 6,020 °F), releasing 11.8 kJ/g. Oxyacetylene is the hottest burning common fuel gas.

Oxygen is industrially produced by electrolysis of water or by liquidation of air and separating oxygen. The gas produced is compressed and charged into cylinder with 40 liter capacity to a pressure of about 15.4MPa at 21ºC temperature. Calculates the adiabatic flame temperature when n-butane burns in 100% excess air at 1.0-bar pressure. Both air and n-butane gas are fed at 25°C. Heat capaci Densities and molecular weights of some common gases - acetylene, air, methane, nitrogen, oxygen and others ..

Abstract. Experimental apparatus and test procedure for determining ignition temperatures of acetylene both in air and oxygen are described. Results indicate that minimum ignition temperatures of acetylene-air and acetylene-oxygen mixtures are lower than those reported in the literature.

For example, an acetylene/oxygene flame may be neutral (equal mix: complete combustion, white rounded cone); carburising (excess acetylene: large smoky yellow flame); or oxidising (excess oxygen: short, sharp inner cone, deeper purple hissing flame). The rate of acetylene reduction by detached nodules of Alnus and Hippophaë was found to be correlated with temperature between 4 and 20°C, and with oxygen tension between 1 and 15 per cent O2. No further increase in rate occurred in nodules of either species when the oxygen tension was increased to 20 percent. Alnus continued to reduce acetylene for at least 20 hours after detachment When oxygen and acetylene are supplied to the torch in nearly equal volumes, a neutral flame is produced having a maximum temperature of 3200°C.

First, at 1 atm for pure oxygen the temperature rises about 37%; at 20 atm, over 50%. The rise in temperature for the methane–air system as the pressure is increased from 1 to 20 atm is only 2.7%, whereas for the oxygen system over the same pressure range the increase is about 14.2%.

Oxyacetylene welding, commonly referred to as gas welding, is a process which relies on combustion of oxygen and acetylene. When mixed together in correct proportions within a hand-held torch or blowpipe, a relatively hot flame is produced with a temperature of about 3,200 deg.C. Acetylene produces the highest flame temperature of all the fuel gases.

If a flame is formed the temperature is about 2,800-3,000°C. 2019-03-11 Acetylene when combined with oxygen burns at a temperature of 5600 °F to 6300 °F, highest among commonly used gaseous fuels. As a fuel acetylene’s primary disadvantage, in comparison to other fuels, is high cost. Chemtane 2 Acetylene produces the highest flame temperature of all the fuel gases. The maximum flame temperature for acetylene (in oxygen) is approximately 3,160°C compared with a maximum temperature of 2,828°C with propane.
