What is the fuel range for pure ammonia in terms of its concentration in air?

The correct answer pertains to the fuel range of pure ammonia in air, which is understood to be between 15% to 28%. This range is significant because it defines the concentration of ammonia in the air that is flammable and can support combustion.

Ammonia is a type of fuel that requires a specific concentration in a mixture with air to ignite and sustain a flame. Concentrations below the lower limit of this range (15%) do not have enough fuel for combustion, while those above the upper limit (28%) are too rich for ignition to occur.

Understanding this range is essential in safety considerations and managing the use of ammonia in various applications, such as in chemical processes or energy production. Providing this knowledge aids in preventing unsafe handling and storage of ammonia by ensuring it remains within the defined safe concentration parameters.
