Deflagrations experimental production

Detonation limits have been measured for various fuel-oxidizer mixtures. These values and comparison with the deflagration (flammability) limits are given in Table 7. It is interesting that the detonation limits are always narrower than the deflagration limits. But for H2 and the hydrocarbons, one should recall that, because of the product molecular weight, the detonation velocity has its maximum near the rich limit. The deflagration velocity maximum is always very near the stoichiometric value and indeed has its minimum values at the limits. Indeed, the experimental definition of the deflagration limits would require this result.
