At what temperature will an ammonia air mixture ignite in an iron flask?

The ignition temperature of an ammonia-air mixture is a crucial piece of information when working with high-pressure piping and chemical processes. At 1204 degrees Fahrenheit, this is the temperature at which the mixture can spontaneously ignite when contained in an iron flask, facilitating a combustion reaction.

This specific ignition temperature is important for safety and operational protocols in industrial settings. Knowledge of this threshold allows engineers and operators to design systems that prevent conditions which could lead to an explosion or fire. Understanding the ignition temperature assists with the proper management of ammonia in air to ensure that it remains below this critical point under normal operating conditions, therefore reducing the risk of ignition and ensuring safe handling and use.

The other temperature options, while still high, are above the established ignition threshold for ammonia-air mixtures, which indicates they do not apply for ignition in proper contexts.
