Under ideal conditions, what is the ignition temperature of natural gas?

  1. 800 degrees F

  2. 1,100 degrees F

  3. 2,500 degrees F

  4. 3,500 degrees F

The correct answer is: 1,100 degrees F

The ignition temperature of natural gas is typically around 1,100 degrees Fahrenheit. This is the temperature at which natural gas can ignite and sustain combustion in air. Understanding the ignition temperature is crucial for safety and efficiency in gas heating applications, as it provides a benchmark for when gas appliances can properly operate without the risk of explosion or incomplete combustion. In practical terms, knowing this temperature helps technicians set up systems and troubleshoot potential ignition issues, ensuring they maintain safe working environments. In contrast, the other temperatures listed are either too low or excessively high for the ignition of natural gas, which can lead to potential misunderstanding about safe operating conditions.
