The limits of dust explosibility
Fire Technology, 1967Over the past half century, the dust explosion hazard has been attacked from many angles. This paper examines the problem, briefly reviews past efforts, and discusses recent modifications and techniques for measuring explosibility limits.

Nature, 1931
IT was stated long ago that the kinetics of gaseous reactions do not submit to the laws of classical physical chemistry. In particular, deviations from the law of mass action are best of all illustrated by the presence of the pressure limits for a thermal ignition.

Explosion limits for combustible gases
Mining Science and Technology (China), 2009Abstract Combustible gases in coal mines are composed of methane, hydrogen, some multi-carbon alkane gases and other gases. Based on a numerical calculation, the explosion limits of combustible gases were studied, showing that these limits are related to the concentrations of different components in the mixture.

Structure of the thermal explosion limit
Combustion and Flame, 1988Abstract In a closed system an explosion limit is the transition region which separates the regions of slow and explosive reactions with respect to initial conditions. In the present paper the characteristic features of chemical reaction in the transition region are investigated for thermal explosion.

The determination of explosion limits
Recueil des Travaux Chimiques des Pays-Bas, 1937AbstractThe author proposes to accept the progressive reaction, which is possible in many gas mixtures (and mixtures of solid substances) when the reaction is started locally, as the criterion of explosivity. An explosion limit is then exclusively a property of the mixture under the given conditions and the confusing “influence of the ignition” can be ...

An analysis of the explosion limits of hydrogen-oxygen mixtures
The Journal of Chemical Physics, 2013In this study, the essential factors governing the Z-shaped explosion limits of hydrogen-oxygen mixtures are studied using eigenvalue analysis. In particular, it is demonstrated that the wall destruction of H and HO2 is essential for the occurrence of the first and third limits, while that of O, OH, and H2O2 play secondary, quantitative roles for such ...

The effect of stirring on the limits of thermal explosion
Combustion Theory and Modelling, 1997It is analysed theoretically how the stirring of an exothermically reacting fluid layer affects its thermal explosion limits. Analytical and numerical analyses reveal that, in accordance with the intuitive expectations, the short-scale stirring makes the thermal explosion more difficult through the increased heat transfer to the boundaries.

Upper Limit in Explosive Chain Reactions
Nature, 1933THE existence of an upper limiting pressure for explosion in thermal chain reactions has been explained in two ways. (1) The rate of branching of the chains, at the limit, is just sufficient to balance the rate of gas phase deactivation of the carriers ; (2) a sudden change in the nature of the absorbed layer of gas on the walls of the reaction tube ...

Detonation limits in composite explosives
Symposium (International) on Combustion, 1965Characteristic differences in the effect of density distinguish composite explosives (based on ammonium nitrate or ammonium perchlorate as oxidizer with an organic fuel) from molecular explosives like TNT or pure ammonium perchlorate. The behavior suggests that the reaction slows down when density is increased in composite explosives, while in ...

On limiting distributions in explosive autoregressive processes
Statistics & Probability Letters, 1998Let \[ Y_n= \beta'\widetilde{Y}_{n-1}+ \varepsilon_n, \quad\varepsilon_n\text{ i.i.d. } N(0,1), \quad n=1,2,\dots \] be the \(p\) th order purely explosive autoregressive process where \(\beta= (\beta_1,\dots, \beta_p)'\) is a real \(p\)-vector, which is unknown and \(\widetilde{Y}_j= (Y_j,\dots, Y_{j-p+1})'\).
