The fuel range for pure Ammonia is _____% to _____%?

The correct fuel range for pure ammonia is 15% to 28%. This range indicates the lower and upper explosive limits of ammonia when mixed with air, meaning that ammonia can ignite and cause an explosion only when the concentration is within these percentages. Below the lower limit of 15%, the mixture is too lean to burn, while above the upper limit of 28%, it becomes too rich for combustion. Understanding these limits is essential for safe handling and operation in environments where ammonia is present, as it directly impacts the safety protocols and risk management strategies that need to be in place. Recognizing the correct explosive limits is crucial for preventing accidents and ensuring proper use in industrial applications.
