Analysis of the effect of boron-containing compounds and combustion catalysts on paraffin combustion rate in an oxidizer flow

Abstract

Abstract The paper addresses to the experimental investigations of the combustion of test samples of solid fuels based on paraffin and boron-containing compounds and combustion catalysts in the gaseous oxygen subsonic flow. Tests were carried out at the atmospheric pressure and oxygen flow velocity from 27 to 31 m/s. The mass combustion rate of the samples increased by 28% when ammonia borane was added to paraffin, and by 16% when sodium borohydride with a bit of solid oxidizer was added. The biggest amplification of the mass combustion rate using the catalyst reached 5%.
