What is the hottest oxy acetylene flame?

approximately 6,000 °F
The inner cone is where the acetylene and the oxygen combine. The tip of this inner cone is the hottest part of the flame. It is approximately 6,000 °F (3,300 °C) and provides enough heat to easily melt steel.

What temperature should a cutting torch be?

A cutting torch diverts the oxygen and mixes part of it with the fuel gas to create the preheat flame, forming the ring of flame around the cutting tip. This preheat flame will reach a temperature of 4400°F to 6000°F, depending on the fuel gas used as well as the ratio of oxygen to fuel gas.

Is acetylene hotter than Mapp?

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 transport, allowing a greater volume of fuel gas to be transported at the same given weight, and it is much safer in use.

Is oxy propane safer than acetylene?

Acetylene will ignite at mixtures from 2.5 percent to 82 percent, while the range for propane is 2.1 percent to 9.5 percent. Based off of these numbers, it’s easy to argue that propane is much safer to use than acetylene. However, keep in mind that these are both flammable gases, and both need to be handled with care.

At what temperature can an oxygen cut first be started?

around 960°C
Before cutting, the cutting torch has to pre-heat the steel to ignition temperature at the starting point. At this temperature of around 960°C (depending on type of alloy), the steel has lost protective properties against oxygen and is still solid. Pure oxygen is then directed through the nozzle at the heated area.

How hot is a butane torch flame?

2,610 °F
Consumer air butane torches are often claimed to develop flame temperatures up to approximately 1,430 °C (2,610 °F). This temperature is high enough to melt many common metals, such as aluminum and copper, and hot enough to vaporize many organic compounds as well.

What is the temperature of oxygen burning?

1.4. 2 Practical Considerations

Fuel	Oxidizer	Temperature (K)
Heptane	Oxygen	3100
Hydrogen	Air	2400
Hydrogen	Oxygen	3080
Methane	Air	2210

What is the coldest fire?

A cool flame is a flame having maximal temperature below about 400 °C (752 °F)….Parameters.

Compound	CFT (°C)	AIT (°C)
Isopropyl alcohol	360	400
n-Butyl acetate	225	420

Can you use MAPP gas instead of acetylene?

“MAPP gas” is also widely used as a generic name for UN 1060 stabilised methylacetylene-propadiene (unstabilised methylacetylene-propadiene is known as MAPD). MAPP gas is widely regarded as a safer and easier-to-use substitute for acetylene.

Is propylene hotter than acetylene?

Using propylene for cutting results in more BTUs of heat for more effectively heating large parts and thick metals. Also, the chemistry of propylene results in better heat transfer properties than acetylene which means you can increase productivity by producing faster cuts.
