Flame temperature refers to the maximum temperature reached by a flame during combustion. It varies depending on the type of fuel being burned and the conditions of the combustion process. For example, the flame temperature of natural gas can reach around 1,960 degrees Celsius, while that of propane can exceed 1,980 degrees Celsius. The flame temperature is important in various applications, including industrial processes and safety assessments. Higher flame temperatures can lead to more efficient combustion but may also increase the risk of damage to equipment or surroundings. Understanding flame temperature helps in optimizing combustion systems and ensuring safe operations.
