What is the flame temperature of oxygen with natural gas?

The flame temperature of oxygen with natural gas, which typically includes methane as its primary component, reaches approximately 4,600 degrees Fahrenheit. This temperature is achieved because the combination of oxygen and fuel gas generates a highly efficient and intense flame. When oxygen is used to enhance combustion with natural gas, it allows for a more complete burn, producing higher temperatures than would be possible with air alone.

In the context of oxyfuel cutting, this high flame temperature is critical as it enables the efficient heating and cutting of metal materials. Although other flame temperatures are listed, they exceed the accurate value for the combination of oxygen and natural gas under normal operating conditions. Therefore, 4,600 degrees Fahrenheit is the correct answer, reflecting the specific characteristics of the oxyfuel cutting process using natural gas.
