WebFlammability limits of methane{nitrous oxide{nitrogen mixtures show no pronounced dependence on small amounts of oxygen (<5%). Generally speaking, °ammable gases with large initial amounts of nitrous oxide or ammonia show a strong dependence of °ammability limits on ignition energy. 1 Introduction 1 1 Introduction WebThe rich flammability limit is about 4.8% by volume or partial pressure. Flammability limits are not absolute, but depend on the type and strength of the ignition source. Studies on flammability limits of hydrocarbon fuels have shown that the stronger the source of the ignition stimulus, the leaner the mixture that can be ignited.
