In processing, transporting and storing combustible liquids and gases, people rank the flammability limits as a crucial safety index. Therefore, many researchers carry out experiments on or set up prediction models for them. In this research, we want to investigate the mixing of combustible gases and combustible gases of pure oxygen. Theoretical models to predict the upper flammability limits of mixtures that with two organic combustible gases and estimate the flammability limit in pure oxygen of combustible gases.
Mixture of combustible gases based on the ability to grab oxygen relationship, developed a model to predict the upper flammability limits of mixtures, through the literature experimental data of methane - propane, methane - ethylene, methane - acetylene, methane - Isobutane and propane - n-butane to regression analysis showed that the prediction flammability limit model is apply to the five combinations.
From the viewpoint of mass-energy balance and use adiabatic flame temperature of combustible gas of air to estimate flammability limit of pure oxygen, the results shown that the predicted value is close to experimental data, so this prediction model can be as a quick state to estimate the flammability limit of pure oxygen in Industry.
