THE COMBUSTION OF MIXTURES CONTAINING POTASSIUM PERCHLORATE AS OXIDIZER AND METAL FUELS IN A VACUUM
Abstract
A study was undertaken of the individual stages of the combustion of mixtures containing potassium perchlorate and metal fuels in a vacuum because, by means of a vacuum test, it is possible to determine whether the initial combustion stage of the mixture takes place in the condensed phase or whether the mixture burns only in the gaseous phase. Stoichiometric mixtures containing KC104 as oxidizer and W, Zn, Mo, and Ti as fuels were used as research objects. Grains 5 mm in diameter were compacted to the maximum density. Tables present data such as results of the self-ignition temperatures of the mixtures in a vacuum and the sizes of the metal particles; surface temperatures of the mixtures during flameless combustion in a vacuum; results of the determined rate W of flameless combustion of the mixtures; results of the solid and gaseous phase analysis for flameless combustion in percentages of the initial batch. It was concluded that: The initial stage of combustion of every mixture occurs in the reaction layer of the condensed phase, i.e., on the surface of the fuel particles,with a total positive heat of reaction, and it ends in the generation of a smoke-gas combustible mixture which then burns in the region above the surface of the mixture until, under certain conditions, the final combustion products are formed. (2) Self-ignition of the mixtures occurs at a temperature at which the metal is in the solid state.
