What types of flame are obtained in oxy-acetylene gas welding?
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
What alkynes produces the hottest flame when burned in oxygen and is primarily used as a fuel gas?
Acetylene (C2H2) produces the hottest flame when burned in oxygen. It is primarily used as a fuel gas for welding and cutting metal due to its high flame temperature.
Why does the reaction of hydrogen and oxygen gas excel in the presence of a flame?
The rate of this reaction is increased at high temperature.
What is the difference between a yellow gas flame and a orange gas flame?
Well like with any flame, the lighter the flame, the higher the temperature of the flame. If the flam is burning Yellow, it is at a higher temperature and is burning more oxygen than an orange flame is. That is your difference other than the color.
What gas bursts into flame when it reaches oxygen?
air will burst into flame in pure oxygen
Why air mix with the gas in the barrel of the burner before the gas is burned?
Air mixes with gas in the burner barrel to create the right ratio of fuel and oxygen for combustion. This mixture ensures efficient and complete burning of the gas, producing a clean and controlled flame. Additionally, the air helps regulate the temperature and intensity of the flame.
Does flame cutting use a neutral flame or slightly oxidizing flame?
Assuming that you are using the Oxygen-Acetylene cutting process; both, depending at what stage/phase of the cutting process you are in. What we encounter is a gas flow differential problem. With the cutting torch flame properly adjusted (the acetylene valve opened to the point where the un-mixed acetylene flame is burning without producing any smoke but still in contact with the cutting tip of the torch, the oxygen valve is slowly opened until you have adjusted the flame to a neutral quality or setting. Press the cutting oxygen lever; typically the flame will become slightly carburizing ("feathers" will appear at the ends of the pre-heat flames) this phenomonom occurs because of the drop in line pressure due to the high flow of oxygen through the cutting tube or orifice. With the oxygen lever remaining depressed, readjust the flame to a neutral setting. This will cause the flame to become slightly oxidizing when the cutting lever is released; since an oxidizing flame burns slightly hotter than a neutral flame the pre-heat of the metal that is being cut is faster. When the metal is at the proper pre-heat or kindling temperature (1600 F for pure iron - various steel alloys will be slightly different; beginning to turn bright red is a good indicator) depress the cutting oxygen lever, the flame will revert to "neutral" and the cut can then begin. Weld. Prof.
A gas that burns at a very high temperature?
which gas burns at a very high temperature
Which gas welding flame is the hottest?
It's called a Neutral flame. Enough Oxygen is added to the fuel to allow almost complete combustion. The remaing fuel is combined with the surrounding air and burned. This is the best flame for most cutting and welding operations. Too little Oxygen produces a Carburizing flame. It is yellow and produces smoke. A slightly Carburizing flame is used when welding Aluminum. Too much Oxygen produces an Oxidizing flame. It begins to sound louder and the inner flame comes to a point.
When the carbon dioxide gas was poured over the flame why was the flame extinguished?
Carbon dioxide is a heavy gas that displaces oxygen, which is necessary for a flame to burn. By pouring carbon dioxide over the flame, the oxygen around the flame is depleted, causing the flame to be extinguished.
Which gas extinguished the flame?
CO2 is th gas used, if you starve a fire of oxygen then it wont have anything to burn
What is the maximum temperature that can be achieved by the yellow flame of a Bunsen burner?
The maximum temperature that can be achieved by the yellow flame of a Bunsen burner is around 1,000 to 1,300 degrees Celsius. The temperature can vary depending on the air-to-gas ratio and the quality of the burner.
