Explosion of gas–air mixtures in coke production

Аннотация

The combustion temperatures of mixtures of 43 highly inflammable and combustible liquids with air are determined at constant volume, at concentrations corresponding to the upper and lower limits on flame propagation in conditions of constant pressure. The results show that these temperatures are approximately the same for different materials. The combustion temperatures of air–vapor mixtures containing a safe (according to handbook data) concentration of retardant may exceed that of the limiting compositions. This raises doubts regarding the validity of handbook data obtained in tests in small chambers. The limiting combustion temperatures of mixtures containing air and the gases and vapor formed in coke production are calculated; these results are required for reliable determination of the retardant concentrations of inert gases.
