Studies in acetylene flames. Part I. Extinction

Abstract

The extinction point of acetylene was determined by burning a vertical he under constant pressure and in an atmosphere consisting of O2 and N2 of constant composition which could be altered at will. The length of flame, the diameter of the combustion chamber, the velocity of the gas mixture through the combustion chamber, and the percentage excess air all affect the extinction point. The results under specific conditions are given in the conclusions. The presence of CO2 in the inlet gas mixture increases the value of the extinction point but to a lesser extent then that previously found for other hydrocarbon gases, e.g., methane.

Combustion

“…They investigated the ignition limits corresponding to the n and t2 regimes and contributed extensive discussion to the mechanism. Other investigations contain additional data on hydrocarbon oxidation and deal with the problem of reactivity of hydrocarbon molecules (181,229,768,802). A series of papers was published by French investigators that deals with the explosion limits of mixtures of hydrocarbons or related compounds and oxygen (255, 266, 296, 297, 606, 637).…”
