WebFlammable mixtures of hydrogen in confinements such as pipes or ducts, if ignited, will readily result in accelerated flames and conditions that can lead to transition to … WebThe lean flammability limit is 3.2% H2, 76.5% Ar, and 20.3% 02. This is slightly lower than the value of4% hydrogen in air. The rich flammability limit is 76.4% H2, 18.6% Ar, and 5% 02 which is exactly the same oxygen content for the case of hydrogen in air. For practical purposes the rich limit of 5% 02 is the
